Hi guys, I purchased gaskets a few months back for my upgraded ct off of ebay, I recently went to the track (ennis) to have some fun with the 3s crew at the texas 3s gathering, The first pass, I lined up against a G35, I knew I had the race in the bag, I got the tires cleaned up a bit and setup at the lights. I knew I was going to smoke him, I had a pretty smooth launch (street tires) and got them to bite and as soon as I hit second the exhaust note got EXTREMELY loud. I glanced at my gauge and it was at 3psi... Needless to say, I lost an easy race. 15.5 at 89 :nono: . A month went by before I got the balls to tear into it and found the gasket between the housing and the manifold was GONE(I left it at the track with my ego). Please learn from my mistake, buy Toyota exhaust gaskets, you wont be sorry.
