exhaust: how loud?
 

i just ordered some HKS 2.5" inlet 3.5" tip mufflers and im gunna run custom piping back from my rb header/cat. is this gunna be a really loud setup? i have a older style hks cat back on the car now and its got a really nice tone...atleast it did before i got an exhaust leak somewere.

If you have a catalytic converter and mufflers, that shouldn't be TOO bad.

Removing that exhaust collector on the side of the engine does cut down on the noise, but with full headers (vs pre-cat replacement pipe) you should just get a bit more volume without ruining the exhaust note / tone.

i have a 86 N/A Rx-7 with no caty. conv. and dual 3.5 inch outlet exhaust, it LOUD, good sounding loud though:)
