Nothing better than a mechanic that lets you watch his every move ;o)

[@turbogeoduck1]

Sounded nice! You could've introduced the mechanic, though. Come on, kid! Otherwise, a great video.

[@JesusIsGod222]

" we got the 02 sensors out , now we working on the upper bolts " no your NOT . HE is doing the work . give him all the credit !

[@Slow370Z]

Oh stfu who cares. He clearly can work on his car.

[@JesusIsGod222]

Grant l But clearly is not humble enough to give some 1 working on your car credit on the video. Is something you learn early . Is too late now.

[@jarule7703]

He's right son, saying "we did" is a psychological flaw. Also having his ugly ass face in every thumbnail like a lil girl doesn't help. Also the dude must be so annoyed that he was just hanging around.

[@stevornrichards1380]

He did give him credit. He said he's glad to have an actual professional do it. Y'all a bunch of girls coming on his channel just to hate. Nitpicking everything and quoting shit, makes me wonder if y'all bend down to pee

[@CallMeGodlyPvp]

Ja Rule what car do you drive? Lmao.

[@killabandit]

You need to get your car tuned now by UPREV. My NISMO 350Z with High Flow Cats, and MotorDyne Shockwave Exhaust, and AEM Dual Intakes, did 295 RWHP which was high for the HR engine in that year 2007. Get the tune and you will easily see around 20-30 to get all the mods work together nicely.

[@blademanx]

KillaBandit hes at 313 whp

[@killabandit]

Dumb ass. He has a newer generation Z. You can't compare 295 rwhp to his gen which I said. He needs a tune still to put him up to 330ish.

[@r3dRoVeR247]

I have a 2012 nismo. I have berk HFCs with armytrix exhaust and stillen gen 3 and after my uprev tune I only made 309 whp

[@killabandit]

Something is not right especially if this one in the video made more than yours without the tune.

[@pherron7471]

[@reidspencer]

should have gotten a ART pipes bru

[@cristobalmartinez1142]

Where can I get them n will the clear the check engine light..

[@shuura]

Be cautious with breather mods on the '15+ Nismo's without a tune. I'd installed an FI CBE in mid August and Stillen Gen 3 Intakes almost a month later on mine, and went limp mode after going WOT. I was just a week away from tuning when it happened, and thought the intakes were the cause. While tuning with Sebastian (Specialty Z), he mentioned that it's common with Nismo's as they're tuned aggressively from the factory for the stock parts. When you increase airflow, the factory tuning does not compensate well. After my tune, all was perfect!

[@nemesisc4926]

shuura that's with the G too. It happened to my g37

[@CleanCarbonZ]

Nismo is not tunes any different. Lol

[@IggyFresh]

[@angelm5888]

Indeed

[@mizzle04]

Just goes to show you don't always need 600$ art pipes to accomplish a simple task of freeing up airflow. His numbers are good for the money spent. I've seen new Z/Gs here do 320whp after installing CAI, TB, plenum, LTH, full exhaust, and uprev/ecutek tune. That dyno could also be a bit flattering.

[@sneak916]

mizzle04 art pipes are known to free up more mid range torque though

[@IScoreUnderPressure4]

The 350z also has a carbon fiber driveshaft.

[@_baller]

That looks like a second muffler not an H pipe....

[@dropful2347]

tommy d u b b s so he removed his catalytic converter right ?

[@Chris-gi1yx]

Did you consider Art pipes? What made you choose the AAM? Sounds great btw.

[@louisvazquez2904]

Chris because they gave them to him I’m sure. Everything else on his car is aam. In my opinion and not because I have them on my z but ART pipes FTW.

[@nukexD]

I read that the Cats and the suitcase muffler are the most restrictive things on this car, good thing you got rid of those! And I know you’re and AAM guy but I wanted your opinion on Art pipes by Motordyne. Great video btw!

[@BrosFOURRSpeed]

nukexD I've only used AAM on my Z's. So that's all I know lol. No complaints with their products

[@ahumm8280]

@@BrosFOURRSpeed that brand is sold at nissanraceshop.com which is a nissan dealer in CA so it must be compatible with the stock tunes.

[@Nismotosh]

@brosfourrspeed did you have to get a tune after getting hfcs installed?

[@matthewnyden]

Art pipes produce the most power, hands down. They are test pipes though. If you don't want the smell from the exhaust don't do aam, go with fast intentions resonated hfc's. This kid obviously doesn't do any of his own work on his car.

[@pierrevezina7531]

Hi . What would be the best exhaust to buy ...buck for the money . I dont want to spend $1200 . I there anything that would give a nice sound ( not too lound) without being expensive .thank you for your advice .

[@VerisimilitudeDude]

Look on Amazon. There's a sweet exhaust on there for only $308 that looks and sounds just like an HKS exhaust. It's from Auto Dynasty.

[@nickestopinal5549]

I would look into the Manzo exhausts. I have a Manzo V2 exhaust for my G37 sedan and I'm very pleased with it. It's not too loud, just a lower register than stock. Quality of welds are good and fitment was just about perfect. I got it for around $350. With the Manzo Y pipe, I'm just over $500. There was also a noticeable increase in HP and torque.

[@dropful2347]

Go with resonator and muffler delete.

[@3819oli]

Really pleased you're happy with your modifcations dude! Im hoping that the latter part of the video was dyno session and tune, because despite being a learning ECU you really need a good remap now! I had very similar modifcations and was running lean as hell before my uprev

[@BrosFOURRSpeed]

Olly W my car is actually running on the rich side. Still up in the air on a tune or not tho

[@3819oli]

Bros FOURR Speed honestly was the same as you, was very much on the fence. That was until I had it done. Now I sing it from the roof tops bud. Just a night and day difference, the throttle response and it all working in tandem has made it a beauty to drive. From one guy to another, dont worry about pub dyno figures, just get it done!

[@BrosFOURRSpeed]

Olly W Really? I think part of me can't get over 'only' 10whp gain from a tune. But I guess there is more to feeling the power than peak dyno numbers?

[@manred6253]

[@krolsky4608]

AAM could have made the sensor placement angle a bit more parallel to the car's bottom. They seem to stick out quite a bit downwards.

[@BrosFOURRSpeed]

Yeah they did. I think I scraped it on my driveway once. But I ended up putting 90 degree extender in to clear the CEL. And that got them out of the way

[@shootinblanks007]

I know this vehicle is no longer in your possession but damn those wheels were awesome

[@BrosFOURRSpeed]

Yeah man this was such a sick setup!! I really like dit! Ended up selling the wheels after they were on my GTR for 2 weeks. They went to another Nismo Z!

[@brettvoorhees]

You think it's too loud to daily? Cause I really like the sound but hesitant on doing high flow cats

[@BrosFOURRSpeed]

Brett Voorhees It's louder with the HFC installed. It's still bearable, but 1800rpm the drone is a bit loud. So if I'm going 45mph, I leave it in 5th gear. Other than that, it sounds really good. Still need to fix the plastic trunk liner so it stops rattling. Cold starts are loud!

[@josephgarcia6007]

I just bought my first car a Nissan 370Z sport. Any recommendations for an exhaust ?

[@BrosFOURRSpeed]

These resonated short tails was the best setup I had! Gave it a great sound without the drone!

[@nadsenec8512]

3.7 v6 321hp only ? stock have 344hp hm ?! nice car brutal sound !

[@hartsickdisciple]

321 wheel horsepower. The stock 350hp is at the crank. They put down about 280 to the wheels, stock. So he's gained about 40 horsepower at the wheels from these bolt-ons and tuning. That's equivalent to about 45-50 horsepower gained at the crank. So his car is now making close to 400 horsepower at the crank.

[@FerasDishli]

👍🏻👍🏻👍🏻👍🏻 Is this mode needs Tune ? Or I can run with OEM tune? Need you advice 🙏🏻

[@coreydukes5725]

Depending on what brand you go with you will get A SES or CEL. While you don't have to get a tune right away your mpg will probably be off i averaged about 20 beforehand with my g37 7AT after test pipes it's about 17.9. The tune is just beneficial imo

[@FerasDishli]

Corey Dukes I will weld MagnaFlow high flow (metallic core), but I don’t want have a tune.

Right when I hit 1k miles after this install the CEL came on. I put in the 90 degree 02 extensions for the bottom sensors and cleared the code. Ironically ended up sellout the next week for the GTR. But I never heard anything from the Nissan dealer about it. But I'd say try the 90 degree adapters. Or just plan on tuning the car

[@BrosFOURRSpeed]

A bit too much to be honest. This was too loud for my taste. I should have just left the resonated short tails. That was the perfect setup

[@quinnguyen4700]

@Bros FOURR Speed …i have your same setup on my 2016 nismo…but without the HFC. I am on the fence with getting the HFC. So with the loud drone noise, do you think i should just not get the HFC and just leave it be with the Resonated Short tail? Reason is…by adding the HFC, i will need to get it tuned after 1k miles cause of the CEL and load drone…and with just added 10 HP…is it really worth it in your opinion? Would love to know your thoughts on this. Thanks

[@stephenkeogh7548]

What size wheels fella

They were 20x12 in the back and 20x10.5 up front. Great setup!

[@GhillieDomain]

thats pretty good power man! thumbs up

[@72mlauer]

Sooo, did you end up passing NC emissions testing?

[@BrosFOURRSpeed]

Well after 1000 miles a CEL came on. I installed the 90 degree 02 extensions for the secondary sensors. But literally a few days later I traded the car for my GTR. Never heard anything from the dealer so I'd assume it worked. From what I've heard the Z is very icy on HFC. Half the time they work fine, the other half of the time a CEL pops up. So plan on tuning the car if you change the factory downpipes.

[@paulbowen3078]

I bought the same High Flow Cats. The O2 Sensors are angled down, I've replaced my sensors twice now. Are you having the same problem? I see from the video that these are angled down also.

[@dropful2347]

Any checking engine light ? Does it hurt the car ?

[@omarm.7707]

I know you mentioned the check engine light shouldn’t come on, but since you’ve had it installed and assuming you still have them on, has your check engine light come on?

[@BrosFOURRSpeed]

Check engine light came on after 1000 miles actually. The 370Z is a picky car with cats. So plan on tuning the car if you do any sort of HFC or test pipes. I ended up trading this in for my GTR right when that happened. So I put in 90 degree 02 extensions and cleared the codes. Traded it in at a Nissan dealer and never heard anything from them about it

[@BrosFOURRSpeed]

In this video I did a dyno run after we installed the part. Never tuned this car, but already had a baseline from when I bought it

[@studiovulcan4411]

This exact setup probably won't differ in sound on a non nismo, right?

[@BrosFOURRSpeed]

The only difference would be your lack of a dual midpipe. So they might be slightly different. Not sure if the different mid pipes have different diameters or resonators. But AAM does have a dual midpipe you could get

[@Austin-yb7ec]

[@BrosFOURRSpeed]

I didn't want to deal with CEL and those would be even louder. The extra 2-3 HP wasn't worth it for me

[@hashims1981]

the additional 10hp came from the installation ? no tune is required?
