I have raptor 660 with a fmf megamax slip on exhaust. I want to get a full system performance exhaust that will be good at the track and trails and won't **** my neighbors off. I am looking for a good exhaust under 96db, any suggestions? Would it be better to keep my slip on and get the powerbomb headers or sell my slip on and get a complete system. Thanks for your input

 

Not really, throwing an aftermarket exhaust on and then choking it up with a 96db capable quiet core will cut a healthy percentage off your power gains.

Yoshi, HMF, LTE and others claim close to those db specs, but have no numbers that I know of with the quiet cores in.
