I've been driving around with an svt header, glasspack, and dump for about a month.. I fear I have lost 75% of my hearing. Yesterday I drove down to BAT and picked up a pacesetter catback for around $200. Put it on thismorning, WOW! It's actually quieter than my stock exhaust was with the header. I can finally hear intake noise again (which, at full throttle, compliments the exhaust quite nicely). I had my doubts, but I'm VERY pleased/impressed with this exaust. I'd reccomend it to anyone who is looking for a nice deep, quiet exhaust.
