I put em on and the ROCK!, I really like how they sound, Yep, they were tight to get aligned, I needed to get some persuasion behind it, but I knew they would go. Glad I went this direction. I'm never going back to stock, It sounds Soooooo much better. No more lawnmower sound and not to loud like the guy here in town with the Cobras (Sounds like a louder lawnmower).
