"light weight inexpensive unit. loud, flanges slightly offset(poor/difficult) fit. unit rubs against under carriage. welded bracing does not line up(need to drill hole in brace to secure). would not purchase again. recommend you spend a few extra bucks for better quality unit. i know i will." posted by: WTH on January 4, 2015 view all 6 reviews

"Installed on my 2000 forester S model hardest part is getting the old one off used dremel and angle grinders takes quite a while but worth it as the car has 130k miles and the dealership wants over $2000 for the parts and labor. Gets it through the inspections and keeps it on the road. Used the same eastern catalytic brand with my 1999 subaru legacy sedan which helped me keep it on the road for over 320k miles before retiring it." posted by: rustybolt on April 27, 2014 view all 12 reviews

"While it is necessary to adapt to pipe size on vehicle, the rear requires leaving part of the previous converter on. i.e. The very end of the old converter. That will be the same OD as the new converrter. The old fitting has to be ground down, or as I did, filed. I might better have used a coupling. When I do the left bank, I may try cutting the old portion off, and adapt down. I shall try the coupling. You must have a local supplier who stocks a wide variety of fittings! They are inexpensive. Remember, the adapters can be shortened to allow slippage while installing. They can always be shortened, but cannot be lengthened once cut off, so measure carefully. Think ahead. Procrastinate. As it is, I am still going to have a friend braze the rear end joint, as it leaks a little. Using a coupling most likely would have avoided the leakage." posted by: suvguy on July 24, 2012 view all 1 reviews
