Hey guys! I just got back from my first drive with the Mac O/R pipe and BBK shorties. (Did it yesterday.) Wow! I love the sound! (Already had a Flowmaster cat-back on it.) I know, most of you guys will say there's no reason to do a header swap (Oh man, I HATED IT!!!! I hate any exhaust work.) but Holy Crap!!! It sounds like a Mustang, now! Woo-hoo!!!! Now for some more mods! Just thought I'd share.
