Well, there would be a picture attached, but I am not very motivated to look through the FAQ and figure out why I am not allowed to post attachments.

Either way, the power increase was felt by my seat of the pants. Seems like the engine revs to redline (where the CVT locks in at WOT) quite a bit faster. With the Megan Racing CBE, I noticed only a very slight difference in sound over 4000rpm. My best description is that the engine feels much smoother under load. It really brings out the high end on the VQ. Totally worth the $292 and highly recommended!

you have to LINK the pictures, not post them as attachments

 

Can you take a video? I'd like this setup just worried it's too loud.

 

nice review makes me want to get one now lol

 

It's not so much a sound increase issue with the y-pipe. It's more about using the silencers or not with Megan CBE.

 

That's EXACTLY correct. Megan did a good job with this exhaust. It sounds wonderful, but when I made a 5-hr drive to Vegas (with stock y-pipe) and forgot to put the silencers in, it was really obnoxious. Lots of highway drone and it did get annoying. With silencers in, it is just barely louder than stock...just enough to hear.

The y-pipe doesn't change the volume. The only way I can describe it is that it sounds smoother...not louder, though. It revs much more freely in high rpms.

You can hook this y pipe up to stock exhaust also?

 

Does the Racingline y-pipe maintain the same exhaust pipe diameter as stock?

By the way, what is the stock exhaust pipe size?

 

hey i got mine installed this week 2.. with megan CBE... i had to reuse the stock gasket that connects the ypipe to the exhaust becuase the one megan brought was too narrow and leaked.. i put the other one and problem solved.

 

yes guys.. you van hook it up to the stock exhaust as well

 

Waiting on the pics.

 

There really isnt any pics to post. A y-pipe is a y-pipe. Stock y-pipe brings each bank into an oval shaped pipe that shapes into circular pipe which leads to the downstream catalytic converter. The RL y-pipe maintains a circular pipe all the way. The biggest difference I can see is that the rear bank of the OE pipe has a longer run than the RL y-pipe. They join sooner. Oh yeah....and no cat in the RL pipe. The RL ypipe is exactly same size as OE. So no difference in fitment between aftermarket and OE exhaust.

You think it'd be possible to get the same results by a custom fit with mandrel bent fittings and a cat delete?

Companies like Dynomax sell y-pipe fittings and various lengths of pipe as well as bends.

Not trying to knock RL's product, just askin.

 

Just installed mine yesterday (RL Y-pipe) with all the rest of the exhaust system being stock. The sound seems more G37 (seems) in low rpm (below 3500) and the tranny gets to the redline a lot faster.

Very nice upgrade for less than 300$...!

 

After having a couple hundred miles behind the wheel, I can officially say this was a much more worthwhile mod than I expected. Living in rural Arizona, the secondary roads are 98% of driving anywhere around here. All 2-lane roads at 65mph and passing vehicles requires lots of 60ish to 80/90ish sprints. I dont like wasting time in the lane of opposing traffic at those speeds. So the biggest difference is much improved high speed acceleration. It just doesnt run out of steam as you start approaching triple digits. That combined with the fact that I'm always at 4500-7500 ft elevation means that sealevel acceleration would be even better. Lovin it!

we demand on having the PICTURE :P

 

link for rl ypipe ?

 

http://racinglineperformance.com/sho...&idcategory=22

 

Any issues with sensors going off or not passing typical US smog tests? RL does say it will pass but curious on everyone else's experiences.

Looking to install the RL y-pipe with current stock exhaust but then upgrade to AAM when the time is right, and when I have the $$$'s.

Does anyone know if there will be any issues with the RL y-pipe into the AAM exhaust? Thanks!

 

There should not be any issues with the CEL or emissons test for that matter.

AAM will not guarantee correct fitment to the RL Y-pipe.

 

The third catalytic converter in the stock y-pipe is not directly monitored. The other two cat's have sensors directly monitored by the ECU.

I would strongly suggest installing all your exhaust components at the same time. This will allow the installer the most flexibility in putting your exhaust back to together.

The guy who did my cat-back hooked it up to the stock y-pipe. I told him about fitment issues between RL and AAM exhaust components but he assured me, with a devilish grin, he could make it work if I wanted.

I'm reluctant to buy the RL y-pipe because of this and the previously described fitment issues. Not sure I wanna deal with that (potential) headache just yet.

 

I've read the thread you're talking about and familiar with that particular issue. I can tell you from experience installing my own RL y-pipe that it shouldn't be a concern for you. If there are fitment issues, then either the y-pipe or the catback was built incorrectly and wouldn't work with the stock pieces either. We're talking about a flange from each piece that mate together, and two bolts to hold it in place. And there's enough flex that (+/-) .5" difference isn't going to mess anything up. I'm certain that the case you read about a one-off mess up. Don't let it deter you.

 

They're actually trying to get me out there to do some test fitting with my RL Y-pipe to see if they can get at least a set of steps down for how to make it fit with this part

 

Yeah, when I was under the car with the guy from the exhaust shop we were looking at the stock y-pipe and the two cats. I was trying to figure out how feasible it would be to rip that stock crap out of there and put in HFCs. And that's when things started to sound like more money and time than I wanted to invest.

I think I will pull the trigger on the y-pipe eventually. The guys at the place I went to really liked the AAM cat-back. Definitely brought a smile to everyone's face when we fired her up.


Are you thinking about ditchin' the Borla and making the switch?

 

Yeah I've always wanted the AAM just had a list of other things I want to do first. At this point I'll probably just be helping with test fitment but I'll pick one up eventually.

 

Guys with the RL and AAM, what sort of fitment issues are you all speaking of?

I have the RL Y pipe on my car and the AAM, but the AAM is still sitting in the box, though in the next week or so I should have it installed on the car. I would like to know what problems are incurred in the installation ? So I can let the exhaust shop know ahead of time.

 

Gents, thanks for the advice! Def looking to put on y pipe and AAM exhaust, time to start saving!

Ghozt let us know what you find out! That's awesome you are close to them.

Sounds like from Serpent it's not an issue. I was going to put them on in a 2 stage process but I guess there is no point if I want both anyway.

 

Remember, I still have the stock exhaust. I just installed the RL y-pipe, and it fit exactly the same as the stock y-pipe. Exactly. No stretching parts to make it fit, therefore, if the AAM would bolt up to the stock y-pipe without problems, it would do the same to the RL y-pipe.

 

I have my RL ypipe installed
And now my next task is to figure out how to mate up the AAM exhaust to it!

 

that's what id think too, but for some reason some people with the RL y-pipe have reported fitment problems. i dont know specifically what type of fitment problems though.

 

I remember what a difference the Warpspeed y-pipe made on my 4th gen. It has me wondering about this one .

 

I should be going in next week for this test fitment + the install of my new AAM exhaust.

 

Please let us know how it goes Ghozt. Just got my y-pipe finally I stalled!

 

Sweet Deal!


I think some of these companies should be paying you for doing all these different type of mods to your max. Talk about free press! heheheh...

 

Got mine... Runs Great!!

 

so here's the deal with the RL y-pipe fitment - there are fitment issues with the AAM exhaust. the RL y-pipe is slightly longer than the stock y-pipe. other exhausts have smaller piping and less exact measurements so have more "play" in their fitment. the AAM is very precisely fit to the 7th gen with the stock Y-pipe. because of this, if you have the RL y-pipe what is recommended is to modify it (instead of your $1400 exhaust) and have a half inch section cut out from the area where the stock cat normally is (where it bolts to the cat-back) and re-welded, which shouldn't cost much. this will create the space you need for perfect install like OEM. also it may be possible to have your exhaust customized to fit before it is shipped, contact Khoi to see if this is a possibility.

I spoke with Khoi about the possibility of making an AAM y-pipe, and after speaking with their team the answer unfortunately looks like no at this time. due to the curves/bends in the y-pipe it would be difficult to produce an affordable product, especially compared to the pricing the RL y-pipe is currently at. the best answer right now is a modified y-pipe, which is definitely worth it to get this badass sounding exhaust on the 7th gen.

ill post up some videos of the sound soon. i am in love with my car all over again.

 

i started up my car this morning to goto work and had totally forgotten about the new exhaust until i heard it start up. all i can say is wow. I just want to cruise around all day now and skip work...

 

Glad that there is actually some better proof to substantiate that (AAM-RL fitment) claim. It's actually pretty interesting to find out that that RL y-pipe doesn't actually have the same EXACT dimensions as the stock.

I checked RL site last night and it said the y-pipe was back ordered or something. Maybe they will read this and adjust the dimensions ... unlikely, but I agree, I'd rather hack up the y-pipe than the pipes from something that costs a grand more.

I knew as we were installing the AAM cat-back that it was a super tight fit. there's very little room (if any at all) to play around with fitment. in fact, i think the AAM installation guide that khoi sent me actually said something about cutting part of the stock heat shield. The only adjustment that had to be made on mine was a hanger for the mid-pipe.

i'll still prolly pull the trigger on the y-pipe in a few months, though. I hope my brother's welding skills are still sharp

 

haha! exactly why I took the (Fri)day off when I installed mine.

 

Haha #TeamAAM!!!! This is true!!

Damn I miss my car (never thought I would say this) it has been a long two weeks!!! Can't wait to start her up... Might have to take mine thru a couple of tunnels this weekend lol
