I installed the Borla Singer on my 2004 Cobra last night. Sounds great. My question is: Has anyone had any problems with the tips not being the same on both sides. I mean one lower that the other? On mine the passenger side is a little lower than the drivers side and also not centered. I'm probable going to stop by a muffler shop and let then fix it. Heat up the hanger and move it. Also how much exhaust tip did you leave exposed? Thanks in advance.........
