I currently have SD headers no cat and the SLP non-resonated cat back (Proflow mufflers). It is annoyingly loud and drone for days. Based on searching the best solution is the 30" glasspack. The car is embarrassing to drive right now as it sounds like a beater that lost its exhaust and no one bothered to fix it.
So i think the Cherry bomb 87516CB is what i am going to do.
Any other suggestions?
