I hope sincerely that you either shorten the length of the exhaust pipes or slide them deeper into the muffler? They are sticking out way to far for stock. IMO of course.

And those clamps I would be weary about. I had them on my GTX with the SLP Catback exhaust and had them removed and had the mufflers welded on. They are gonna leak no matter much you tighten them down. And then they rust? Good luck in getting them off. They had to torch cut them off.

Just some food for thought.
