What Mac catbacks do you guys have on your cars and where did u order them from? Do they come with stainless tips like the flowmaster kits? I'm in the market for a new catback and want something similar sounding to 2 chambers but just a bit louder. I had flows with a catted H, sounded okay but too quiet, now i have a catted x with bullets, sounds like ass except for WOT. I'd be running the new catback with an o/r H.
