Just picked it up - and wow what a difference! No longer do I feel like I'm being followed by angry bees, this thing sounds like a V8 now. Low, great rumble, but far quieter than the RM I replaced. Note that with the new cats that flow about 4x more than the stock ones, and completely open tube design (a plum would roll right through the mufflers) there is the absolute minimum of restriction, with only the 2.5" pipe bends in the system.
Initial drive feel is excellent, throttle response seems better, no drone at all - but again, its so much quieter, perhaps its just the lower tone compared to the higher pitch of the baffle type exhaust.
Now I didn't do a 'before and after' on the sound because when I brought it in I was going to have a pipe cut and moved initially, and as these things tend to do - morphed into a new header back system. I'll get it put together for Cars & Café on Saturday and do some sound vids then. I've got a bunch of work to get it together: Front splitter, Difflow install, etc.
The system is made up of all stainless 2.5" pipe,
Magnaflow Spun Cats and
Magnaflow Mufflers.
I love the look, the sound is totally different than any NSX I've ever heard, and doesn't appear to be loud enough to draw a crowd of cops. I call it a WIN!
More details soon...
