[@KevinBaxter]

I left it to the Road Dirt crew to handle their own video, content, etc. They pulled me in toward the end for a 5 min interview about tuning. Thought you guys may want to see it. More indepth tech on the subject from me coming in the future.

[@kevinblane5281]

Tech Tip... tighten the rear fender tip/right hand Rhinehart muffler... also you can hear the compensator on shut down...Kerker 2:1 works for me!

[@joshbrook6849]

Great video Kevin, would you be able to cover some quieter slip ons and baffles? I have had to remove my Rinehart slip ons as they drone at freeway speeds

[@freebird3190]

Kevin I'm 52 yrs old been riding motorcycles sense 1977 ... Recently found your Channel. Love it man Great videos

[@getoffmygrass6974]

I love exhaust videos but I’m a controlled fuel leak kinda guy myself but injectors are ok too, I’ll never turn away a beautiful sounding Harley-Davidson. Murica! 🤟🏻🇺🇸

[@gdubbsmotolife9713]

Fun and different little video. Rineharts have been a great option for many different motors over many years. Very high quality. Looking forward to seeing that Chevelle

[@KevinBaxter]

Right on

[@jaypino2642]

I have a 2014 Street glide and I put on the 4 in. Rineharts. I love the sound

[@eugeniustheodidactus8890]

I want that 4.5" DBX ! Well done!

[@loupuleff571]

I have Rinehart on my 99 road king it sounds and runs great looking forward to another great video Kevin is the man for doing these videos poor guy looks tired from working all these hours !!

[@KevinBaxter]

tired for sure. they shot the video and handled the content other than a 5 minute interview with me at the end regarding tuning, i was pretty much hands off. thought you guys would enjoy seeing it nontheless.

[@loupuleff571]

@@KevinBaxter always a good thing to learn more even if it seems it doesn't apply to our particular situation not to mention your a good teacher that's not a easy thing to do, get some sleep man !!

[@bluidog2]

My 2013 FLHTK came with some VH slip ons. I’m installing Decatted head pipe and 4” RH slip ons. Also SE high flow breather. Then off to H-D for SE tuner and tune. Done ✅

[@razzrasmussen5773]

Thanks for sharing. I do use Rhinehart slipons with a PM aircleaner. Dealership used Screaming Eagle tuner for Stage #1. Hooah

[@KevinBaxter]

Thanks for sharing!

[@iabsoriw433]

Thats the sound my dude's

[@michaelmorgan5714]

I liked the video as I have every other but I would have liked a comparison at the end on all three sounds one right after the other and maybe a decibel level differences.

[@mikekellam365]

Damn, I can't believe I missed THIS! But I was trying to make the MONEY!!

[@travisgray3331]

nice review...appreciate the insight....I have a 21 CVO RG with the Rinehart 4.5 with dbx and have been told with the phase 1 air cleaner already on the CVO...my tuning should be good. true or False or is it that cut and dry?

[@robertperry1780]

I worked for BUB when they had Rinehart. It is good to see the Rinehart still going after BUB.

[@KevinBaxter]

That goes back quite a few years. I recall Dennis reaching out to me when he was first working on the very first 2-1 from Bub for Rinehart. That was around 2004 or 2005 I believe. We made some design changes and worked with Dennis to show that the true duals back then could back then could perform as well as the 2-1. I haven't spoken to Dennis since the split. Judd has done wonderful things with Rinehart as well since he bought it from Gerald. Great company.

Thanks sir

[@outboundteam8298]

Hey Kevin, Just became a subscriber of your channel after watching just a few of your vids, very informative. I have an 09 street glide with a stage one Hi-flow air intake from Harley other wise it is stock. I am going to install Rine harts DBX 45 slip ons, Can I use a Power vision tuner in place os having it put on a dyno to tune it and map it? Thanks for you r attention to this, Pop's

[@paulrevere4326]

Kevin- I took the converter off my factory header, upgraded the air filter, and a set of neighbor hater slip on muffler. I have a 468 Redshift cam installed as well. Do you have a tune for my Power Vision tuner? I have lost a lot of back pressure and the low end torque is now weak.

[@richardalvis4695]

Reminds me of Borla's exaust for auto. You know, the ones you can put disc in at the end tip?. Neat Idea this is with the bikes

[@KevinBaxter]

Like a Supertrap muffler?

[@richardalvis4695]

So no changing the p.c.m./ e.c.m tune with baffle changes?

[@michaeljkirschner7720]

Someone may have already mentioned this but... when y'all fire up the 4-1/2" the Right side slip on "walks back" about 3/4"-1" (right around 8:27 time). Might could have forgot to tighten something...

[@roberthicks3706]

Ha Kevin what size are the screws holding the tips are they standard or metric or both.

[@jdreneau744]

Hey id like more sound out of my rineharts. I have the true duel setup. 4 inch slip ons with performance baffles. Just real quiet not happy. What can i do to get louder

[@richardalvis4695]

I hear you about the Chevelle. My 57 Ironhead? Same way. Its the Christine of motorcycles. It keeps you aware. Goofy foot shift, hardtail, still running the mag. Stretched, lowered. Disc front and back. Springer and King-n-Queen seat. 9 foot wheelbase. Its the love of my life and one of the most " you better keep paying attention" bikes Ive ever owned. Sometimes Im in the mood for that. Know what I mean? Want to build it for show quality. Kinda the reason I hit you up on your last live stream about the ironhead rebuild. I'm a mechanic now and there's enough info out there that I think I could handle it. I just know you cant beat a man at his trade and think you just might be the shit

[@chrisrussell4738]

Can you drop a link on the baffles and where to purchase? Thanks

[@dw6506]

I have rhinehart slip on’s will I benefit using these baffles as far as sound, I tried ordering from a dealer yesterday but salesman left me with to many questions

[@Duey_diditGarage]

Yeah buddy

[@UsetoCud]

Kevin, you have mentioned heat several times when discussing exhausts. But I haven’t heard about ceramic coatings and it’s affect. There are some companies that claim a reduction of half the heat, such as Jet-Hot. Your opinion please.

[@KevinBaxter]

it can reduce heat a bit no doubt...especially if coated inside and out.

[@paulhorvath9784]

Hi,,Kevin you're talking bout Touring Bikes that have the Cat in the Header.. I run the Vance n Hinse Eliminators 300 Slip ons on my 20 M8 FXLRS and Bike Seems to Run Great ,with some additional power , better cooling and excellent mileage..No tune..It's my 3rd new HD part from other bikes..Do you agree with my Perception Regarding the Slip ons on M8 Softails ? Thanks.

[@KevinBaxter]

a little different on those. if the cat is removed, i feel strongly that the bike should be tuned...regardless of the format.

[@keithgriffith6002]

In my opinion nothing beats the sound of a CFR

[@ihatesjws669]

Any comments on how the different baffles would effect the power and torque curves?

[@KevinBaxter]

historically i have seen the standard baffle produce the best power averages for tq and hp in the 4" but this was their deal...a sound test. maybe power will come later.

[@carolinarider5237]

I can't find these baffles for a 2015 RK. It's all 2017 and up. I know you said that one is a 2014. Where can I find these baffles?

[@HOLMESLAMONT]

Less revving and more ilde. Nice video

[@KevinBaxter]

i agree...lol

[@1500frank]

Been searching for the DBX replacement baffle that was used on the second install . I can only find the HI-FLO BAFFLES FOR TWIN CAM HD AND INDIAN TOURING is this the one the guys used on the Street Glide in the video , Thanks, Cheers From Newfoundland Canada >>>

[@matthewgrant7867]

Try Fortnine. It’s where I got my dbx baffles for my 4” Rinehart’s

[@richardperry5880]

Hi Kev . I have got a tri glide 2015 with a stage 1 fitted from Harley uk . We have to mot out bikes every year and now the laws have changed with loud pipes . I have got Vance & Hines mufflers fitted with fiber glass baffles . To try and make it quiet . Will this do any damage to my trike if I do this . All fit original mufflers fitted from standard ??? 🇬🇧🇬🇧

[@KevinBaxter]

nah that wont hurt it at all. wrap around baffles isnt uncommon at all.

[@josephhebel6981]

What's the difference between the DBX and the Hi -Flo baffles?

[@bobgoes4129]

Like the different sound, but how this changes the tuning?

[@KevinBaxter]

it would some...but this video was their script. tuning may come later.

[@porkchopxpress3741]

Where do I fine those retaining rings for the baffles???? HELP I can not find them anywhere...

[@KevinBaxter]

Rinehart should be able to get them for you.

[@DarkHorseParatrooper]

Mine were super hard to slip back in...

[@Bacon75420]

Phil, we want to hear it at idle too

[@ardyrides834]

The discontinued Rinehart 3.5" slip-ons sound best.

[@Cwra1smith]

Great! Now stick a cam in it!

[@emanuelwalls3534]

Where can I purchase the DBX’s40?

[@emanuelwalls3534]

Nvmd

[@lostsoul8806]

It would help if you tighten the clamps on the slip ons.

[@CapnDrift]

I realize this channel is all about Twinkies and M8s, but... Some of the older folks might recall the Alphabet 2 into 1 from back in the Pan Shovel days. Man, those things were bolt on performance. Of course, carb tuning (remember carburetors? ;^) was required, but back then it weren't no thing. We built a replica for my Pan/Shovel: with the duck cut end even. Mine has a baffle in the can rather than packing, but it too made a world of difference. I thought I'd have to jet down after the change, but I had to go up! It's not quiet, but it's not obnoxiously loud either. Yeah, I understand that with a cat, the cat is the tail wagging the dog. Bad, cat, bad, bad... Heh. I'm looking forward to the M8, Twinkie builds. Some of my friends ride Twinkies and I like to stay abreast of the new fangleds.

[@KevinBaxter]

Oh im right there with you....not all about TC and M8 at all. Just happens to be the series im running now. Heres a few others though that might interest you. There will absolutely be evo, pan, and shovel stuff coming...building several right now in fact.

Hey Kevin does your shop have like a showroom? I am local and thought about a swing by and picking a T-shirt that you do for charity if you still are doing them? I know I seen that in one of your videos? Oh you look like a little guy? Do you carry them in mens sizes? or should I say fat mans sizes?

[@KevinBaxter]

Showroom? not really....i have to use every square inch for bikes and equipment lol. yes we have shirts here and i believe i have a few 2xl and 3xl left. email [e-mail] and he can have a look. thanks.

[@richardalvis4695]

Ahhh, nevermind Kevin. Needed to watch all the video. My bad.

[@kevincollins9731]

Would have liked to have seen this on a Dyno , not to see motor numbers just to hear the difference in sound under a load.

[@vanislandsteve]

👍🏻🇨🇦

[@porkchopspapi5757]

I guess that's a m8 engine cause it sounds like a Japanese or European bike.

[@jameslanning8405]

Anyone want to buy an "04," Heritage Softail? All stock, nothing over built... Lot's of chrome, good tires, teal blue and silver paint. Good condition, new clutch cable, brake pads, spark plugs. about 12,500K miles, runs nice... I've decided to get out of the HD world... $5,000.00 firm...

[@fagen2222]

Must be me but all sound much the same to me ?

[@ericatanas2481]

Kevin, I’ve always have appreciated your videos as they are very informative. As a speed shop and specializing in performance engines, it’s disheartening that you are providing such content that holds no real performance. I think most are aware that this company doesn’t apply an engineering principles to this application. It’s sad to see this posted with your name attached.

[@greggriffin3242]

Did nt like the 4.5

[@ianwalker7934]

I don’t need noise , I need Horse Power and Torque

[@Thebwaller07]

Don’t believe the hype that 2 into 1 is better, true dual won’t make enough power. Don’t believe you need to omit 02 sensors. Find a real tuner that knows how to map and tune Harley’s. My 2020 RGS has reinhart DBX 4.5’s with true duals and a certain cam with a certain tuner. It sounds sick as hell and will kick a lot of ass. 😊😊😊

[@thomasobrien5976]

Please stop using button head screws they are awful

[@coronado1701]

You ruined an excellent video by constantly gunning the motor without getting good any idea how they sound at idle.

[@philmclamb1219]

I agree!

[@KevinBaxter]

So do i....i basically let them do the video...kinda their thing. i posted because it seemed to be good info, changing baffles, etc. more idle wouldve been great. lol.
