Overal Grade- A

This exhuast is a lot of bang for the buck! Looks pretty nice, but the fitment does require some pretty minor tweaking. Also, there isnt any type of gasket between the muffler and headpipe. So far, as the exhaust is still brand new, there isn't any leaks, but dont forget the exhaust port gaskets (they aren't included)!

Mac 3/1 Chrome Megaphone Exhaust System

Great exhaust! Easy install with ni modifications. Had some concerns over ground clearance during right turns, and I have scraped once, but I did that with the stock exhaust. Great product. Great finish! Great look! Great sound. 5 stars. Paul
