I have a 2015 black sho. Stock with 89k miles. Had it for 1 year and now the sunroof, trunk, and windshield leaks. Needs cats. Thinking about going with ppe catted downpipes. Already have a k&n. Was looking for a tune by ajp if he still does them. I heard he was the best. Any way to find out if he does? Thanks ahead of time. BTW this is my first time on a forum.
