Need HELP with those who have installed a UPR X-pipe!

[RGurleyJr]

After installing my UPR x-pipe on my 98, I found out that it doesn't fit right! I thought the gasket on the passenger side was leaking but it turns out that the flange on the x-pipe itself does not mate up to the exhaust manifold outlet, after I bottom the nuts on the studs, there is a gap on the left side of the flange where exhaust is leaking. I have tried adjusting the x-pipe to get the passenger side flange to sit right but there is still a gap, it's almost like they welded the flange crooked and that one side of the flange is hitting the exhaust manifold first and not letting the rest mate up. Has anyone else had this problem? Can anyone offer any advice other than selling it and getting another brand?

the gasket is know for going basd on that side. the best thing to do is take it all back out. put the pass side on FIRST and tighten it up. then connect the rest.

Make sure you dont install it all in 1 peice.

Do the passenger side first, and Saleen is right, the gaskets are notorious for going bad (mine did also) and it sounded like a dump truck.

After you do the passenger side and have it attatched to the catback do the drivers side pipe. Its a PITA if your just doing it on jackstands, it might look straight when your under there but in reality its all jacked up.

You need replacement studs, NAPA sells them.

You are not the first person I have heard that had fitment
issues with the UPR X pipe. Should have got a Bassani X pipe
and you wouldn't be going through that.

As the others said just start with the pass side first, then go to the dirver side. I installed my UPR X and it fit like a glove, no probelms at all with it.

UPRs got one of the best reputations for fitting correctly that ive heard of.

Bassani is way too expensive for alot of people, plus I dont like a "stamped" X pipe. Definaty a quality product though, ive seen them brand new out of the box and I was impressed.

Same here, install it in peices starting with the pass. side and go buy a new gasket as well.
