    I am very impressed. cost effective, very low car friendly, good build quality, good fitment, deep and aggressive tone, and not raspy.

    Isr really nailed this product as far as single exit exhaust go for the G37. The fitment is very good and leaves plenty of clearance especially if youre lowered. And you cant beat the price either. Ive personally been waiting on this product for awhile and im happy to say it was worth the wait. Sounds really good too just gets a little raspy between 3-4k if youre running test pipes but other than that im very satisfied
