you guys thihnk FI sounds nicer than gthaus ? Gthaus sounds more "obnoxious" i guess but not in a super bad way if that makes sense lol. So hard to judge by video clips

They both nice. GThaus is even louder.

I am running the tomei exhaust (z1 headers and tomei TP)
youtube: ZAtlanta exhaust competition I'm around 4 mins I believe

I had both and personally I feel GTHAUS sounds much better, they are both nice though.

FI non resonated here. So glad I waited for this amazing exhaust!!!

Hks

I recommend GTHAUS.

Sorry to revive an old thread, but I was curious if you guys noticed much of a gain over the stock NISMO exhaust. I saw that F.I. (for example) claims a 20hp gain with their TDX exhaust, but that's on a base model, right? Just wondering how much of a gain there is over that NISMO exhaust.

I also think this is the best sounding exhaust. F.I. is second, but too loud for me.

Well I can officially chime in and say not the ARK from my opinion. Heard one the other day as the guy took off and it truly sounded like a Civic...with bees...in a coffee can. Once again, just my .02

Was contemplating on an Ark CBE, until you mentioned the angry bees.

He probably had test pipes as well. I had the Ark DT-S exhaust with stock cats and it sounded great.... no rasp or tin can angry bumble bee sound at all. Put on some test pipes, hated the sound and ended up selling it

I just ordered atheist SS FI with 18" resonators. Think I'm going to call Toney tomorrow to change my order to CF non-resonated. Hardest decision I've made all year!

I had FI longtubes, FI 18" resonated x-pipe, and FI SS canister cat back when I had my Nismo Z. The sound was amazing and very deep for a V6 engine. Even my drag racer camaro friend complemented me on how it sounded. Only problem I had was after a few miles my car turned into a rattle trap. First the trunk lid and then the dash. Im sure it wouldnt take much to cure those problems though. For power and sound go with FI

FI to me sound awesome!

My wife drove the Nismo the other day and when I heard her pull up I was amazed how dam good it sounded
