Rating: (see review/s)

"The part comes with no instruction other than "With air tube" and "without air tube" stamped to the heat shield. The flanges, although they spin and have larger holes gave me little problem, but my concern is that the converter is installed backward. The emission figures significantly increased shortly after the install. (Immediately after install, the figures were the same as with failing stock converter)." posted by: Phil on October 14, 2010 view all 2 reviews

"If you have never put a converter in and are google impaired then you are doomed with this product anyways. What I have found on google that will help with installing this is point the extra stem hose thing that sticks out towards the engine. I passed emissions so I figured that it was the right way to put it on." posted by: monkey on August 28, 2012 view all 4 reviews

"was a bit smaller than ordiginal, but fit into space provided quite well. Required some modification to the exhaust system, like using reducers to fit into the intake fiottings. I had to go from a 2" to a 2 1/2" by using 2 coupl;ers and brazing them together and then brazing to the cat." posted by: Feldspar on July 23, 2011 view all 2 reviews
