I just got a 99 with 4 inch straight exhaust on it. I need to put a muffler on it to pass a safety inspection in the state of Utah. What can I get that won't loose me much performance?

I put a hushpower on and it actually lowered my cruising egt's and boost and my turbo spooled up faster.

I have heard great things about the Hushpower, but personally, I like the sound of the RBP mufflers... Rolling Big Power makes some great SH1T
