i honestly do not know what version i have. i do know its a 3 piece and stainless. i actually ordered a UPR and got the Pypes, which is ok. the specifics when i ordered labeled the pipe 99-04 2v. i like the pipe but the leaks are driving me nuts. its not terrible, but noticeable inside the car under a load.
the generic crush gasket i got from advance auto parts fit well on the drivers side "collector". i had to do something because after the inital install the exhaust was beyond horrible. it still leaks some tho

. is this where that sleeve you speak of goes? what is it and how do i get one? how much is it? how do i install it?
where the legs connect to the X, we tried out best to eliminate the leaks but could not using the clamps that came with it. ordered some wide band clamps and installed these a few weeks ago ( i kept the clamps that came with the kit ). still leaks

. should i reinstall the clamps the kit came with and just absolutely tighten the pee-waasee out of them? we got them very tight but was afraid to go much more.
please understand im not unhappy with my x pipe, just not overly happy. IMO, there is not mid pipe out there that will fit absolutely perfect.
thanks for the info and any help. very much appreciated.
.....sorry for the hi-jack
