i got tired of the noise my car too. so i threw in a dynomax super turbo muffler. i use a thrush 28 inch glasspack as a resonator no rasp at all. hopefully it wont be too loud if i go catless. i have msds headers and y,with full 2.5 inch exhaust. the resonator was liek $20 from jeggs and the muffler was just $42 at advanced auto parts. most peopel say teh dynomax superturbos suck but it works good for keeping the noise down and flowing good, i dont feel any power loss either.
