Nismo catback vs aftermarket

joey gerein

Mostly sound. Would and after market catback make more power gains as well?

Yes but so little you would only know theirs a difference on a dyno. (>3%)

I tried the FI catback, too loud and DRONING (flame suit on) couldn't even carry on a conversation with passenger, switched to OEM Nismo $280, just perfect sounding now,,,,,some of this may depend on how young U are.

Oh and I sold the stock sport CB to the local Nissan recycler for $185.it was brand new 3K miles

are you referring to the complete nismo exhaust or just the rear muffler?

I was under the impression that only the mid pipe was different between the nismo and the regular Z. I imagine the nismo muffler is probably very similar to a non-nimso muffler.

If mostly sound as you stated and no other planned engine mods, an axle back should be fine.

If you are looking for sound with a slight performance increase go with a NISMO (less expensive) or aftermarket mid pipe and keep the stock muffler (it's louder than the NISMO muffler). This will make the car sound significantly better without the cost of a full cat back.
