where is a good well known site to buy an x-pipe? thanks

 

Ebay...

 

Just put on a complete exhaust system(cat back) and included an x-pipe in the process. My lightning now has a true duel exhaust system and is legal in Calif. too boot. My system is magnaflow and it sounds and works great. Do it right if your are going to do it.
Mark.

 

so why would someone remove the factory dual exhaust and install a single exhaust in the first place????
