Nismo vs Stock Axle Back only.

jwick · 02-01-2014, 03:08 AM

see if you can find a stock g37 muffler. its a bolt on and will procured a better exhaust note as it got grandfathered in before Japan changed the noise requirements. I sold mine to a Z owner for $50 a couple years back

Main reason i asked is because of the AAM Mid-Pipes i currently have.
Seems like the majority got it confused with the whole nismo exhaust. (i know it sucks)

Im interested on the Axle part only, is it less restrictive than the base muffler?
My interest sparked from the Nismo Dyno sheet.

NEW! AAM Competition S-LINE Midpipe (H-pipe/Intermediate pipe combo)

Reason for my interest, plan on adding a HFC later. Figured it will sound and preform better than having the Short Tails with HFC.

Or could the Nismo numbers be because of the nismo tune?

also the nismo exhaust that comes on the car is made by Autech. theres a little nameplate welded to it.

Sorry to bump the thread. But i still find posts provided a bit unclear as it led to midpipes or about the full nismo exhaust.

Short Tails got a bit annoying for the wife. So i plan on swapping those out by
adding back my base muffler. I posted this thread to see if anyone knew if the Nismo Muffler (axle part only) is less restrictive than the base muffler. I want to maximize my chances of keeping better gains between those two.

Thanks!

There's a DIY where a guy cut open a Nismo muffler to make it less restrictive (and louder). From the looks of the internals, it looks like a pretty standard muffler design so my GUESS it that the Nismo muffler is not any less restrictive than the Base muffler.

I had the OEM Nismo cat back on my Base for a couple months. At WOT it honestly didn't sound much louder than stock. I noticed more of a difference while cruising / lower RPMs. It's a tad louder and has a slightly deeper tone to it. I read one thread suggesting it was the dual pipe design of the Nismo that attributed to the sound difference, not so much the muffler. Hope this helps.

the nismo muffler is a better flowing muffler than the base Z, you can google around for the flow pattern, it just isnt louder than base
