So i'm new to mustang forums but currently own my third Mustang. It is a 2007 GT and when i bought it, it already had BBK LT headers installed but has a catted xpipe and of course i want to go with an off road xpipe. My question is; i know Dr. Gas used to manufacture X-pipes which bolted right up to BBKs LT headers and performed MUCH better as well as sounded better than BBKs xpipes did. I am wandering it anyone knew of any other company or companies who still did the same now as Dr. Gas has unfortunately closed the doors to its exhaust division. Thank you in advance to all who respond.
