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.

DIY - Modified NISMO Exhaust - better sound, better power
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.
