Rating: (see review/s)

" was not able to install them to the Headers/Exhaust port. The flanges they use were too big, and did not allow bolting up to the exhaust manifold. The flange and pipe flare were too long, and they would not allow me to thread up any bolts to the exhaust manifold. Since the exhaust manifold has studs that are only 1 long (see photo cat1), there is limited room to thread bolts. The pipe were cut and flared with about a half inch, then the flange was over 1/2 inch, then the gasket, which meant that I could not bolt them up. Removing the gasket there was still not enough room, since the flange is very thick. I did not have a shop to remove the additional space needed for the bolts, so had to return them.

"I ordered this catalytic converter for my 4runner. I had it professionally installed. Within days, my check engine light came on. This part was defective from the start. I am extremely inconvenienced because even though it is under warranty, I will have to pay another $300 for the new one to get installed since labor is not included in the warranty. I will never purchase this part again!" posted by: Casper on December 11, 2014 view all 2 reviews
