Glad I run a TBR. Almost went with the HPI for way more money. Goes to show you don't believe the hype. Thanks fellas I'm feeling good about my choice.

[@grimeyhonkyracing3938]

Tbr looks better too imo

[@darrengysbertsen2169]

Tbr sound like shit hpi sounds incredible hands down my buddies tbr is garbage

[@ecrusch]

Thank you for doing this. It really helps guys figure out what to go with, without having to lay out ridiculous amounts of cash. DAMN dude, almost 1/2 a MILLION subscribers !!! (Well Deserved).

[@shane8493]

I absolutely love these comparison vlogs & I really can’t wait for the D&D

[@RawDawgRandy]

I'm about to pull the trigger on a sawicki but now I'm gonna wait for this vlog to come out. Perfect timing.

[@timbutler3213]

I went with Freedom Performance 2to1 for my 21 Fat Boy and although their customer service completely sucks once they fixed the problem I’m stoked with the pipe. Looks and sounds awesome and have me a bit of extra pep too.

[@HOLYSHIFT]

Great info . Thanks. That puts the end to my dilemma if to go on a 28 week wait list !

[@ericalmager9085]

Glad I made the decision I did, very happy with my TBR. Made the decision off the stage 2 117 Vid y’all made. Thanks for the honest content guys!

[@JakobKaizen]

Is it as loud as everyone says?😁

[@slayer04031974]

I always loved the parts with the knowledge and wisdom of the show when it regarded to enjoying life..Making the show more about living your life outside the battle and surviving

[@chriss19827]

Great video as always! I'm still rocking the sweepers on the fxbb, but these 2 to 1s be calling me.

[@Yahmomma]

Great video , cant wait and see the d&d up for comparison.

[@Bskullz99]

I am excited to see what you guys get out of the D&D exhaust. I have 2020 Street Bob with a 128 Stage 4 and recently had the D&D bobcat put on and wound up with 149hp and 154tq. And that is with A1 performance heads and a fueling 592 cam. Im hoping you guys blow those numbers out of the water.

[@stevendebay1291]

😮😮😮😮😮

[@Sean-yk2cf]

TBR rocks. I also like the shorty pipe. Looks very clean and simple, but strong.

[@nancyweems5270]

Glad you mentioned octane and weather 👍

[@fallenyolo]

Just bought a 21' FXBBS and have been looking for an exhaust couldn't decide between 2-2 and 2-1, my friends have convinced me that 2-2s just really aren't worth it so I've been looking at 2-1s and Couldn't decide between a turnout or comp-s. Perfect timing!

[@Torch114]

Hells Yeah! Gotta give it to TBR for the win and I think they sound much better. Great video Blockhead. It’s all for science.

[@zacharyfett2491]

I had a TBR on my Low Rider S and I thought it was great. I also didn’t ride with a passenger, nor was it a turnout version, so there weren’t any complaints from people around me.

[@dylans7742]

Even if the new Horsepower pipe has partial gains, the TBR pipe is still the winner for price point and availability in my mind. People swap pipes and intake because it’s the biggest gains per purchase note anyhow. Nice job guys!

[@tgkelly5828]

For Science! Excellent as always, add the Fuel Moto Contender to the list!

[@ericalmager9085]

Y’all should also do an SP Concepts pipe as well.

[@dfc193]

Thank you for making this video! Guess I'm keeping my TBR... 131 builtFeuling with 140/160

[@ericnay7733]

Throw a Bassani road rage mid length in there too! I’m just curious about it because I threw one on my 107 road glide with a zippers rs 468 cam tuned with the screamin eagle tuner (for now) I got 106hp and 118ft/lbs torque. Not sure if that’s concerned a good gain. I personally love it, it’s a blast. I just think it’d be cool to see where that pipe falls in the mid length shoot out on goldzilla. Regardless, I’ll be back for every video!

[@alaingroenen8505]

Can’t wait for the Sawicki, I have the long version for my 2020 street Bob and planning on doing a star racing 30/30 cam

[@billiardbago7500]

I'd like to see bassani in the mix. I really liked mine. But either way I love these comparisons.

[@montrussell]

Great video!

[@KyleStanfield]

I don't know if D&D will do the best, but I will say you definitely need a hopped up engine to get the most out of the Fat/Low/Bob cat pipes. I got the Low Cat with standard louvered baffle on my 80" Evo that's a stage 3 (10.2:1 comp, Woods W6H .590 lift, Zippers Max Flow air cleaner, headwork/ported intake with 1.9 intake" and 1.61" exhaust valves, though still using the Keihin 40mm CV carb with 195 main and 45 pilot jets) and it makes great peak numbers but the lower end suffers a little (though not much, and nothing like it would with a drag pipe) compared to other pipes simply because it's still 80" and it can only move so much. I went ahead and got that one though because once I wear that engine out, I plan to replace it with a worked S&S 111" or 124", which I think is where it'll really shine. The D&D sound with that aggressive cam is great though-sounds like butt cheeks clapping on a wet fart, just like that low gruble you get with a properly worked 1970's muscle car.

[@bigfootgarage2201]

The TBR exhaust is my favorite sounding exhaust in the M8

[@michaelmitchell5909]

I dig the tbr for the sound, hpi got the look...be cool to see u guys get a new vance and hines 2 into 1 stainless mid pro pipe they just come out with....they have the stainless air filter too looks damn good.

[@willyafg]

U have links to these?? I dont see em on VH website. Funny thing I noticed while searching is they put cats into their dresser duals. Communist epa mustve been breathing down their necks

[@ashpunting]

My man, Chris, always looks smooth. Will BLOCKHEAD be doing in-house clothing in the future 👌🏾

[@johndough5346]

Great video. Thank you guys. Would love to see thunderheader #s

[@soldier09r]

Eye opening test for sure.

[@michaelmiller9966]

Thanks Dr Wideglide for you cool information! Block peace!!

[@streetglide_bum]

I got great results with a bassani 2 into 1 so it's worth comparing

[@duffy1298]

Love my hpi. I wish it cleared 14s but it’s still sick

[@delallum5654]

Hey guys! Is great to see how good your garage has grow and so good jobs are you doing there! ❤👍👑👏🏻👏🏻👏🏻👏🏻👏🏻

[@palmettolowlife1996]

How about SPC vs Horsepower inc ? That would be very interesting to see

[@VPCustoms]

Lookin good, soundin good! 🤘🏼

[@journeyofjerry820]

For a $900 dollar difference TBR all day unless you just got money to throw away. great video and information.

[@509Jedi]

You guys though about doing a Thunderheader or RedThunder Exhaust just for the old school two into one numbers? 🧐

[@TechnoRoxNG]

I'd love to see the Bassani Road Rage 3!

[@OkDude7861]

I’ve loved TBR on both my harley and street bikes, but I do think the HPI sounds the best in person. Up there with Stealth Pipes it just gives it that little bit more character you can’t hear over a camera mic 🤌🏻

[@JakobKaizen]

Is the TBR as loud as everyone says?😁 I’m stuck between the TBR Turnout and the Stealth Turnout. I want LOUD without the sound being weird and cracky if that makes sense..

[@yamaha450man]

@@JakobKaizenI don’t feel like my tbr comp s is that loud. Maybe I just can’t hear

[@Yargilfist]

Man, I keep hearing DnD exhaust, but keeping thinking for a plsit second that you're talkingt abour Dungeons and Dragons xD Both sound pretty dang awesome on the 'Zilla. Was awesome seeing some of the more techincal stuff again.

[@patrickcaudill2939]

Quite informative 👍🏼 Would be noce to have decibels for the pipes as well Not going to test the Bassani, 2 into 1?

[@InfamousCreep]

The pipe looks cool

[@tommyjusz]

I went with a Bassani 2into1 on my fxlrst. I just cant justify spending any more money on an exhaust considering I'm not doing any other engine mods for the foreseeable future. This proves my hypothesis We ended up with 97hp and 117 torque with a screamin' eagle tuner

[@wiseives]

I prefer the TBR look on GoldZilla, HPI sound might have a slight edge. Good ep

[@BEARDofAWESOMENESS1]

I have a relatively short V&H upsweep and I thought it would cost me power because of all the hype I read online. My tuner said it performed better than he expected. Slight torque dip early but still hit 121hp with just a cam

[@jonnymac8925]

I had the same pipe on my Sporty and I absolutely loved it!

[@wareethan]

I’m running that on my 21 fxlrs and was wondering if I was losing power with it. Little reassurance reading your comment lol

[@DLeeJ]

Can't wait to see the D&D video

[@gncbyron]

Great video, Got a 22 Street Bob with just a Stage 1 that I could drop off and you could do the comparisons on that if you wanted to, Im not far just here in East Orlando.

[@nathanh.9882]

dope video🤙

[@dougwilson7334]

I’d love to see a comparison to a Freedom Performance Combat exhaust. It appears similar to the TBR but with a big sound difference

[@RG-zi6zv]

You should also do a stealth exhaust as well, they are out of Florida! Price is right around 1k

[@joesainato8051]

Good comparison. That’s about dead even numbers and like Chris said the TBR actually took the HPI down low. There’s no doubt if I was buying one of these two I would go TBR and either put the grand in my pocket or use it on other parts. I don’t really think it matters if you have it on a big build like yours or a stage 2 the pipes should still perform the same way just with far lower power numbers. Can’t wait to see the next ones. What I would really like to see is trying a thunderheader or D&D full length Or kromewerks to see what the difference might be.

[@Chris-Devine]

I really would like to see how the stealth pipe compares to all of these too

[@throttleandgrind]

Please do the Bassani Road Rage as well… mercury

[@shawn9922]

Who did the welds? They look amazing.

[@CactusJack252]

You guys should do the high output fab28 pipe next.

[@skyfrogchief2351]

Love this! I have same setup but with Trask Big Sexy. I love it, however it is sooooo hot on the leg.

[@alexanderdouris2127]

How about a thunderheader high pipe? Curious to see how that stacks up against the competition

[@travismccarty515]

Correct me if I'm wrong but yall are running pump gas Correct? What is it in Florida 91 or 93? Also I'm so happy yall have the time and desire to put this kind of content out for us, cause let's be honest this really is the kinda shit we care about, what sounds good and goes fast! Looking forward to the D&D and Sawiki numbers.

[@BlockheadMoto]

All our test are done on pump gas, bc let’s be real, that’s what we use in our bikes! Here in FL, we run 93 👍🏼

[@benzoeller351]

Would love to see stock!!

[@sammyvices2547]

I would love to hear a Vance and Hines upsweep on your bike they still sell them on jp cycles but make sure you get the spacer kit for the rear brake

[@j.e.p8117]

That's wild

[@508knucklehead]

Love these style videos. I think at this point you pick what you like.. between these 2 pipes. HPI FTW for looks

[@journeyofjerry820]

A extra $900 for only looks? seriously?

[@508knucklehead]

@@journeyofjerry820 it’s a sick pipe, paint can cost thousands 🤘🏼

[@carlmcdaniel1946]

I have a 1994 ultra with a 127 ultima and i put true twins on it and it sounds really good a head turner i no i loose a little on the bottom end have put twins on a bike before

[@mikaldavid3760]

Spb fab makes a really good exhaust also

[@andrewsumner5388]

Nice work fellas crime scene investigation at its best!.. love the bike!…

[@brettlynch2707]

throw a thunderheader on that setup as well, its one the original performance pipes.

[@matt_wrx4775]

Full length shootout? Thunderheader vs d&d ?

[@shane8493]

The TBR is better because the torque is where you want it in rpm range PERIOD!

[@GamingLINC999]

Can you do the bassani Road rage plz for science

[@garyehrhardt3136]

Nice R & D content

[@sickunit2096]

These test comparisons are great. Has me wondering…would Bassani 2-1 mid length HP numbers be substantially different from the Slyfox “Ty-brid” 2-1 from Bassani. I just put one on my Bagger and love the look and sound. Titanium is nice and light but is it really worth it on such a heavy bike..?

[@Foothill_74]

I would like to see numbers on the SP Concepts 4.5 big bore

[@oldschoolmobile]

The D&D Fatcat makes great numbers with a smaller CR540 cam in a 131. That would be my 1st pick for power.

[@petecarvo9284]

How about a V&H Pro Pipe? Those are really popular in my area.

[@dwight072]

I was just talking about this the other day. That some independent shop dynoing different exhaust systems or any part for that matter

[@Two-Dads]

How about an SPB Fab and a Fab28, be great to see those bad boys too

[@anthonybongorno7285]

need to test a BURNS Stainless.. best pipe imo

I wonder how the Trask sets up. Hp wise vs 9ther pipes. That's what I run on my 22 low rider s

[@capecodbiker9902]

How about a fab 28 pipe. I just put a full length on my street glide I have not got it on Dino yet. For comparison but I feel like it’s better

[@Jake_RollinThrottle]

@Blockhead I've got a brand new 23 FXLRS if you happen to need a stock bike and want to put those pipes on for testing.

[@Silverdiablo1788]

Would love to know what flannel that is and brand, awesome flannel

[@harryhowell5644]

I wonder where the S&S and Vance and Hines 2 into 1 fit in with these.

[@robbyclark6915]

Does it shoot flames?🔥

[@Midnight-330]

Both are good looking exhausts. Every time there is an exhaust episode, I get the nostalgia of the "new exhaust in parking garage sound check "

[@BlockheadMoto]

Lol those were some great sound checks to perform 😁

[@youtubesux6361]

Cycle shack slash cuts. Hands down the best

[@ryanbeck8425]

I love my HPI 2 into 1. The quality, workmanship and look is incredible. Plus USA made by a great group of guys and gals/Company. Owner, Jimmy Light will personally tune your bike as well.

[@lexustech48]

I heard a 2" holesaw and long shank air chisel work well on stock exhausts....

[@badfxlrs]

Can you test a Jekill&Hyde 2in1 Exhaust? It would be intrested.

[@garyguiste]

…was thinking about the sword openers!!! Bring ‘em back!!!😁🤙😎

[@orthchris]

Glad I didn’t pop for the HPI, ended up with SPC Big Bore pipes for my M8.

[@223remington3]

I recommend Red Thunder 2-1 or Thunderheader 2-1

[@Mikey_556]

Weight difference between hpi setup and stock? Road glide stock vs hpi shorty weight?

[@per4mexbagger541]

Bassani or TBR for my 21’ Road Glide Special ?

[@joeplem5329]

I wonder how much power I'm leaving on the table having a v&h duel radius on my dyna street bob 110 tire shredder 🤔

Please test a SP concepts!!
