Replacing nismo exhaust with?
 

I have a 2011 nismo and I am looking to get a new exhaust.
I've been looking at a few options and the most common route seems to be Fast Intentions.
The obvious issue is I don't want to get an exhaust that has less gains over the regular stock exhaust than the Nismo. I don't want to make less power haha..I guess the FI was dynoed at +20whp and the Nismo is around 20 crank hp?

Summary: So my question is.. Will the Fast Intentions exhaust have any noticeable gains over the nismo exhaust? What other options are there in that price range?

Thanks in advance

I asked the same question to FI about their catback before I ordered my stuff. They said that the NISMO dynos about 4-6 RWH higher than the base model.

I have a '12 NISMO, and I upgraded my exhaust to the Fast Intentions Resonated Test Pipes and their catback with 18" resonators. I didn't do any dyno runs, but the car feels more peppy and responsive.

I'm sure there are others with actual dyno sheets to prove the gains, but the gains are there.

Noticeable, no, just maybe the placebo effect maybe noticeable. The stock Nismo makes about 12-13WHP, so an additional 2% WHP will not be noticeable.

You would get more bang for the buck with test pipes and an intake.

I replaced my FI with a stock nismo exhaust, sounds way better(quieter) and no noticeable HP difference.

:ugh2:

I would replace with the FI CBE.

I noticed there is a deal online for ISR resonated test pipes for $95 (regular 180)
However it looks like there is only one o2 bung...???
Its a good deal considering FI resonated test pipes are $380..but I also don't want CEL...

my vote is motordyne art pipes and shockwave e370 exhaust!

Whatever you do, I suggest you go for full exhaust as opposed to a piecemeal approach.

I went with ART Pipes to replace my factory cats because that will probably get me the most power & tq per dollar while still retaining the nismo exhaust for now. Plus it won't be raspy like regular test pipes (or so I've heard), and won't lose a bit on bottom end like some test pipes
Eventually I will either get Fast Intentions or Motordyne catback but It's not a priority anymore
