i have a custom exhaust (2 1\4) with a high flow catback and dc headers and a apexi muffler. it sounds good but i want something a lil quieter and smoother. some people say to put the resignator back on . will a bolt on catback system sound better. if so what kind would be good.

 

Putting the resonator back on will make it sound deeper and less raspy but it will still be loud..

And some bolt on catbacks will sound better and some will sound worse..The queitest aftermarket system is the hks sport...A little pricey if you have a crx..It costs like $200 less if you have a hatch..
