Ok so I know there is and official exhaust thread with clips and all that but it just doesnt help me enough. Originally, since im a pretty new mustang owner, I was just looking for a simple upgraded exhaust. 6er then I 8er showed me a great one that I planned on getting. But Ive been browsing the clips and watching youtube videos and I realized, I definitely want more. Plus I just found out there is a shop that specializes in exhaust down the road from my house, so I said screw it im goin all out. So if you guys want to help me out im looking for dual exhaust coming out the back. I dont have a GT bumper but I have seen alot of videos with the pipes just coming out under the bumper and it looks pretty good too me. I open too alot of suggestions for mufflers. I still am a fan of the thrush welds ever since 6er showed em too me. But really i open to your suggestions since im pretty new to this. My one rule is I dont want to have to deal with something that wont pass emissions, because I dont want to have to deal with all that ****. So your suggestions are welcome here and I really appreciate it.
