Did any of you have to weld or clamp the joints on your test pipes? The one I recieved has a tight fight on one joint, but the other the bell end is expanded to much. I contacted Omni, and there saying it should be welded or clamped. I don't recall anyone ever posting that they had to weld or clamp the joints.

 

i just got an omni also and was wondering the same thing

from the way they are connected, it doesnt seem like it would leak

 

most cars don't need to be welded but depending on your header and exhaust set up. is a good idea to get it welded.

 

Mine is was pretty snug when I installed it, so I didn't use any clamps. I don't hear/notice any leaks so far...

 

Man...I would never buy a premade testpipe. Just go to any exhaust shop and have them fab up a custom perfect fitting one for 1/2 the price
