Race car sound? I think so!
 

I've been a proud owner of the AAM S-Line Short tails for a little while now, about three months, and have enjoyed every minute...

But naturally, because I am young and dumb and have plenty of hearing left (that could be disposed of), I decided to gain some horsepower and also get some more sound.

Inspired by Road America's VSCDA event in early September (somewhat), I bought AAM test pipes and an eBay Y pipe.

I must warn those who want a loud exhaust, this is almost as loud as it can possibly get. The only resonated portions which remain are the two 12" resonators on the stock midpipe, after the Y pipe section.

The majority of the rasp occurs at the common point of ~3000 to 4000 RPM. There's a bit of rasp if you're under 1700 and giving it more than maybe 50% throttle. I'm sure those who want to eliminate this rasp would use (R)HFCs, res'd test pipes, or perhaps the motordyne Y-pipe with the resonated or cat section.

I have found a few videos where the exhaust is mostly straight piping, but most seem to be custom fabricated. This "solution" is easily made with 500 dollars and all off-the-shelf components. The lack of a tune, however, means that I have lost a lot of the bottom end torque, until I hit 3000-3500 RPM, at which point, even the VDC has trouble controlling the power.

The following are some Youtube videos which may help some people who want a loud exhaust. You might have a light wallet or just want to get a specific sound. No offense to anyone, because my wallet is always light.

Time for long tube headers and a newly developed midpipe section...

Videos in the spoiler.

To funny ..man that has some serious rasp and drone..but love the drive by..not my taste but pretty cool to know this type of set-up..

Sounds GREAT!

congrats on your thousandth post! lol

I'd like to see if yours is louder than mine lol I'm runnin non-red cbe and non-res test pipes. Only thing on mine to kill the noise is carbon fiber cans that's it lol

depending on your cat back, I'm pretty sure the volume might be the same, just different sound. I'm all pipe now, not even any muffler sections.

Fast intentions tdx cat back no resonators and fast intentions test pipes non res as well. It's super loud and mean lol

thanks

LTH is where it's at then...

that scream is what I'm after

I guess it's time to buy some long tubes and fab some piping for the midpipe! I gotta be even louder!

I've been thinking about taking my exhaust off and running just test pipes lol

do it!

connect them and put a cones/megaphones out the passenger before the rear passenger tire ala viper!

I hate to be a downer, I thougt it sounded horrible. It's way too raspy and the drone is probably worst in person. It's more Honda Civic with a busted muffler than a race car.

I was just gonna put 90 degree turndown on them but I gotta find out if it hurts the engine doing that

Nice setup, a little to raspy for my taste

It is indeed raspy as hell, and that's how I feel; I'm on that divide between thinking it's just fart can instead of race exhaust.

I feel that's also where the long tubes will come in and fix that issue.

I think you'll just eliminate way too much backpressure. You'll have to find a way to do that properly, not to mention that much noise is pretty questionable in terms of "legality."

pretty cool you that you least tried it out. I just don't think I could drive with that much noise everyday. Don't get me wrong, I think loud exhaust is pretty cool, but it definitely needs to scream like that car in the other vid instead of a loud fart.

I feel like the cats are pretty much the only things that keep the rasp out. At least with LTH's you get more of a scream than a rasp. The only thing keeping me from getting long tubes at the moment is due to the fact that I need a tune pretty desperately before I lose all my usable power for regular driving. Running my current combo has me hankering pretty badly for torque before the rasp range. With a tune and dyno time running around 600 dollars these days, it will be a while before I can even get the long tubes at 900+ dollars.

Lol I have the short tails and have been thinking of getting test pipes. That's loud as hell. My girlfriend hates the rasp now. I'm hoping to get stillen g3 soon to help. I like though man! I may have to ;)

Legality doesn't matter to me since in PA and modification to the exhaust is technically makes it illegal. I want more noise lol

Not like your current sound level is "legal" anyway. :icon17:

I'm not sure from the videos whether I like the sound or not. Sometimes I love it and others it seems too raspy. I'd like to hear this setup in person though.

You heard mine at the meet I thought? And mine is super loud and I love it. If I could post vids from my phone on here I would but it won't let me.

I can very much tell you that the gen 3's will only increase the sound, by adding all that engine noise to the mix with your exhaust noise. The short tails are pretty crazy on their own, and if your girlfriend really does hate the rasp, I'd stick to HFCs or resonated test pipes.

In the first fly by video, I shifted into sixth when I passed by my buddy. That's the worst the rasp pretty much gets, WOT at 3-4K. Even to me, it's practically unbearable. Everything after that range is just beautiful, but 3-4K is pretty much considerably "cruising." Unless I'm really on it, I normally don't go above 4500, so I hit that range a lot. That's the only thing really turning me off from this current set up.

then get LTH, Y-pipe , 3.5'' single exhaust with only 1 race muffler .. big cam also change the sound.

You should be able to get the sound you're looking for without LTH. A Y pipe to single 3.5 exit will do it, however you're going to have alot of rasp still. Unless you get a resonator I doubt you will kill the rasp. I've found though that given enough seat time you learn where your rasp RPMs are and get pretty good at avoiding it... takes some time though.

I heard it a little bit when you left, but you didn't really get on it so I could hear the full sound :shakes head:

well we were in a little park so not alot of room to move if i would have gotten on it lol

My single side seems like it's a little louder than that... but without the rasp.

vq's with a single is my all time favorite. may look awkward but it sounds the absolute best. What does your exhaust set up consist of?

I love it... I have wanted a single ever since I bought the car.

I've got a surewin Y pipe, 3 inch tubing to a vibrant quiet resonator through a 3 inch buddy club race spec muffler. I wasn't crazy about the muffler when I got it, but after putting it on the car it looks good.

The downside is that it's so low to the ground...

3 inch piping really doesn't like to fit under the rear diff, especially with my car being so low. I'm about to re-do it soon though as I have a Zele kit coming. It's also about 30lbs lighter than a full Stillen CBE.

oh yeah single for sure will be much lighter. Very impressive! all mandrel bent? what about cats? stock cats?

How much did that cost you all together?

Can't say I'd be able to do a single exit. I have always loved duals, and with the stock rear bumper having two cut outs for tips, my OCD symmetry would get the better of me.

That single exit sounds great. Doesn't seem all that raspy at all, although we aren't seeing much load on it. As for volume, can't really say unless it's in person. That's the only problem with buying/building exhausts. You get the note but not the volume.

If I could, I would retitle this thread as "How To Get a Race Car Sound." So far we've got good contenders!

Of course this is just my opinion, but I have the FI LTH and non res CBE with the cf mufflers, and I LOVE IT. For me it's the perfect mix of smooth deep note and a roar when you get on it. The fun starts at 0:40 :)




Sent from my iPizzle using magic and new-fangled science stuff

this is where i like my TP better then the LTH. yes i know not as much HP as the LTH but its a slightly higher note well atleast i think so lol and my NR TP and NR CBE mix is def what i wanted.....now just wanna go louder!!

Sounds great. I would want a bit more of high rpm scream, but that is pretty close to my goal.

The car has Berk HFCs.

I used all mandrel bent tubing, I don't have any sort of that at my shop, so I had to pie cut some pieces to get the angles I wanted. Tacked it all up and then hit it with the tig.

Cost me close to $700 in supplies after buying all of the SS flanges, muffler, resonator and tubing, ect.

It sounds pretty exotic, I have had a lot of people tell me it doesn't sound like a Nissan. haha.

that off throttle, in between shift, hiss, if only there was a way to cure that with LTHs

i personally like the hiss. mine has a real mean hiss with the TPs :tup:

now you guys are making me wanna buy a gopro to show you what mine sounds like. i dont feel my iphone videos do it justice. i do have a 4S so its good video but idk lol

funny you say that because my buddy has a g37, stillen headers, tps, stillen cbe, and it has a major hiss but my dumb iphone4 can't capture that frequency for whatever reason haha his car sounds amazing through my phone but like butt in person

he recently just added a 1 in 2 out muffler right at the Y pipe, it quiet it down a lot but still has a hiss

I don't mind the hiss at all. It's not like rasp where it's just drone and resonance and your head feels like it's vibrating, or when you can almost feel your eardrums beat to the drone. The hiss isn't that apparent to me, and it sounds pretty cool!

The hiss is pretty quiet, and since most cameras without a separate sound input will normalize, you'll hear the exhaust over everything, because it's the loudest thing.
