Would buy again by longjohn, March 17, 2012

I would buy this again, no need to spend $300 extra on one of the other converters that are offered. There was two things that did not go as smooth as they could have. The converter and manifold are to be bolted together by you, which is okay, but they do not supply you with the 4 nuts to do so. I also had to remove the heat shield from this new convertor as it was making contact with the block and causing a vibration noise. No big deal, other than an hour extra time. The install was fast and the product seems of good quality. I would recommend it, and would buy again.

fit perfectly into the other part. so much easier to install the new one than it was to take off the old one.

Ease of installation with all parts included to complete it. It took between 1 to 2 hours to install without a professional installation specialist. Works well with no complaints.

the exhaust manifold is very easy to install. i recomend blaster spray to remove old bolts and anti sieze for installation of new ones. one bolt for the exhaust to catalytic converter only had threads on one side. had to purchase a bolt and cut off the head to make it work. what started the project was changing the o2 sensors and saw the header was cracked at the wye, but not leaking. apparently this is a common problem
