It allows my GTI to sound the way it was meant to. And $50 less expensive than OEM

Installed in an hour an half by local mechanic. Perfect fit. Had to open hangers a bit but thast it. Talk about a difference she rumbles like she should and the the sound through the 8 gear run up is great. I feel a little more tork and power as well. Pipes are a bit wider and look beautiful. MagnaFlo is no joke. Go with the best forget the rest. Michael Anthony

Bout both upstream and downstream cats for my 2001 tacoma they fit properly in the factory locations all I had to do was weld them in and had zero issues passing smog. Great product. Now I need a muffler

So far everything working great,no engine light

Accurate description of the muffler which fit as it was described. Nice sound.
