i have had probably 3 or 4 of these cat back systems....i highly reccomend them. they are built well and i have not had any probs with them getting raspy. the last one i had was the ebay 3" exhuast...it was the best exhuast i had ever had. fit perfect, was $180 shipped for a full 3" catback. you cant beat it. i will never spend $700 or more for namebrand exhuast..not worth it.
