Loudest exhaust set up out there?
 

Hi guys, I just got a 370z and the exhaust set up is way too quiet for me. What is the loudest set up out there without bypassing the cats?

The AAM Short tails. Incidentally, they're also among the most overpriced exhaust products out there: muffler deletes that you have to pay $500+ for.

i have the greddy turbo tic exhaust and stock cats.... thing is loud

I guess they've lowered the price of the 'base model' tails down to $429. So at least sub $500 now... Still...

Was considered loudest thing in my city for awhile :p
But finally straightened out my A/F raios so shut her up :ugh2:

Best bet is probably GT Haus paired with some HFC's since you don't want to eliminate the cats. fwiw a Z34 with full GT Haus CBE is almost as loud as my Z with LTH's and F.I. non-res CBE.

My Non res- FI with no cats ans z1 headers was bone rattilng loud to say the least, glad I got this turbo to turn down the volume for me :) FI non res is essentially straight pipe with 2 inline mufflers at the rear, and still sounds good.

Depending on how much you want to spend, Meisterschaft is a great choice. Combining their axle back with the mid pipe and front Y pipe collector, will give you an awesome sound. I'll include a quick clip of a setup this setup.

Nissan 370z Meisterschaft GTHAUS Exhaust LAUNCH - YouTube

AAM Short Tails paired with the AAM S-Line Mid Pipes. Would range about $1100. Just get a deal worked out with the vendor.

That is misleading.

AAM short tails + headers + a midpipe = WAY louder than short tails alone.

The GTHaus sounds stupid loud in the videos. And they look sexy as f*ck too!

Can't go wrong with fi non-res and LTH!

Just buy a x pipe and go to a shop to weld up 2.5" straight pipes. This is basically that but I have 2 18" resonators in the mid pipes. The 5k rev maxes out my db reader at 130 db from about 4 feet away. I never tested at further distance. In the car with windows up or down under wot the meter reads 113 db. I do have an ART type catless test pipe setup though.

PS, play this through your tv speakers :)

:eek:

Dear God. Do you drive with hearing protection? On a track that's going to get you black flagged, isn't it?

He said without getting rid of his cats...

I doubt changing the mid pipe will change the loudness very much.

Man, those make my setup sound relatively quiet. Until the wastegates open that is........

Lol no but I have in a jeep wrangle on the highway because of wind noise. If you listen at start up after a second it's very quite. Only WOT is it loud. It's pretty tame just normal DD around town. The cars gutted anyways so you hear everything! On the highway at 70mph with no real exhaust noise its like 90 db I think just from wind, rocks, motor, and tires.

Depends on the track. My bike was 106 db which was the limit per rules at 4 feet from the tip at half throttle at a 45* angle. At WOT at 16,000rpm I'm sure it was pushing 140+ and never flagged at mid ohio, Nelson's ledges, VIR, beaver run, or summit point.

Hell the ctsv's at mid Ohio during the Pirelli challenge makes your ears bleed!

Just run open dump straight from the cats. ;)

If not then have a muffler shop custom fab a 3" pipe straight from the cats to the rear of the car.

GTHaus is the loudest.
Fast intention is the best bang for your buck. no lie.

I think something a 1/3rd the cost would be the best bang for the buck.

Thanks for the input guys I really appreciate it. Any thoughts on a straight pipe set up?

Here yeah go. Buy these, weld up straights, done! You'll love it.

GTHAUS ftw !!!

Full CBE and it's ear shattering at over 3500 RPM.

That's just too loud. There was a member that did something similar and immediately took it off because it was just obnoxious.

I have AAM and I love them. They are loud and people will notice (also from miles away).

hey thats me!
yes GTHaus is loud but the tone is proper. theres loud and then theres obnoxious. if you have lots of drone its bad. the GTHaus is proper. Put it this way, i gutted my trunk so i could hear it more. You cant have a conversation at all but who cares, im here to drive. Anything less than 15 volume on the radio is also completely drowned out :P

Did someone say loud exhaust?



This is with stock cats :bowrofl:

straight pipe, or open headers, dont get much louder then that really

here is my setup though, its loud but not obnoxious, mods in my sig

I didn't say you had to get rid of your cats.
Headers do not eliminate your cats necessarily, neither does a mid-pipe.

And yes adding the mid-pipe to the short tails will make it significantly louder. I have heard with my own two ears :)

Any headers worth doing get rid of the cats. Shorty headers on this car are a waste of money and time. It's long tubes or nothing, and long tubes get rid of the cats, hence his comment.

Alrighty, semantics

Loudest exhaust with stock cats..shorty headers, mid-pipe, short tails

OP asked about the loudest setup. Not what makes more or less power.

Thanks

With the stock cats in place, shorty headers are going to make very little difference in volume. Where are you getting your info from?

Been around for 15 years in road course, drag, NA applications, hondas, turbo subarus - new here but not 'new' at all. But I am glad to be here, enjoying my 370z very much.

I'd bet you lunch a pair of shorty headers on an otherwise stock 370z exhaust would increase in DBs at WOT under load. And it would only be further amplified by a midpipe + short tails. Exhaust components tends to be synergistic especially when it comes to scavenging and cfms.

The thin wall tubing alone would add noise :)

But...yes I would imagine that the long tubes are always going to be superior, stuffing a clumsy collector closer to combustion rarely makes power unless there is a snail attached to it, but OP just wants noise :P

It's possible it would be a bit louder, but like you said- only from a change in tubing. The 370 has a really good set of manifolds as it is. If the OP still has the OEM cats bolted to a set of headers, it's going to cork the majority of excess noise right back up.

Never seen the stock headers, eh?

Take a peek behind the heat shield sometime. There's no "thick wall" metal in there. Shorties aren't gonna be measurably louder if they're going through the stock cats.

Yeah, these aren't crappy log-style cast iron manifolds like some cars have. The OE headers are damn good for a factory effort.

I just ordered AAM short tails for 398 shipped from conceptz. I dont find that too expensive

One of these would definitely make your car have the loudest possible exhaust.

HAHAHAHAHAHA Ill show you in a week! lol

why don't you go for nice expensive tone instead of obnoxious cheap loudness like every other ricey civic out there. Seems like most new comers to the 370z are basically asking how can i be the biggest douche bag by stancing my wheels almost horizontal and whats the cheapest loudest exhaust they make.

Loudest exhaust set up out there?
 

loudest exhaust set-up? yea i got that lol

Do full straight pipes win?
