Going through the building process on my MY06 race car. I am looking for some advice on exhausts. I am looking for a cat back(rules state that this only can be changed). The decibel requirement for the SCCA is 103dB. I was thinking about the j's 70 mm titanium, the t1r 70 mm titanium, going with custom 3" tubing with no muffler. I run the custom tubing setup on my 2000 Civic Si SSC car and made about 96dB ewverywhere I raced. So what do you guys think????? Thank you in advance!

 

No muffler will not pass. For whatever reason the S2000 is really noisy. I run a t1R 70mm with resonator and it barely passes.

 

Yeah man, the stock exhaust is 98db. A Mugen exhaust with stock cat is barely under 103, and a Fujitsubo exhaust is at 104 according to s2000library.com.

So far the ones they say are under are Mugen & Blitz, and possibly the ARC or Amuse Euro Dual. The J's 70mm hit 129db by comparison.

 

I have a Js 70mm and it is loud.

 

^WHAT?
