stiv2k Posted August 31, 2006 Report Share Posted August 31, 2006 So I ordered a Catco universal fit high flow catalytic converter on E-bay for 50 bucks. I ordered 2.25" because that's what the pipe diameter was or so i thought...turns out the inside diameter is 2 inches. Anyway, I got around that by getting some cheap adapter welded on and all is good now. How do you like the custom weld? Some small welding shop did it for 25 bucks near my work.

Cam'ron Posted August 31, 2006 Report Share Posted August 31, 2006 exhaust ubolts FTL get that shit welded dude Quote Link to comment Share on other sites More sharing options...
stiv2k Posted August 31, 2006 Author Report Share Posted August 31, 2006 what's the difference? I only did that because chances are, it isn't welded 100% square and straight and i more than likely needed to rotate it a little to align up w/ the rest of the exhaust honestly, i dont see a difference between welding vs. clamps Quote Link to comment Share on other sites More sharing options...
Psych0matt Posted August 31, 2006 Report Share Posted August 31, 2006 /\ werd, as long as they are nice and tight. they may not look as good, but thats about it Quote Link to comment Share on other sites More sharing options...
Cam'ron Posted August 31, 2006 Report Share Posted August 31, 2006 appearance dude... thats all Quote Link to comment Share on other sites More sharing options...
stiv2k Posted August 31, 2006 Author Report Share Posted August 31, 2006 I agree with you on appearance, but I didn't have much of a choice...plus. it's underneath the car anyways Quote Link to comment Share on other sites More sharing options...
Cam'ron Posted August 31, 2006 Report Share Posted August 31, 2006 maybe im just confused but if the shot welded the adapter rings for you why couldnt they have dont the joint with the ubolt... i agree with you on the under the car thing but i have cut my head on a ubolt before and once on my 81 regal i had one hangin that got cought on a speedbump and ripped my exhaust wide open... i like the welds for more than appearance when you think about it...

I told him not to do it because if he didn't weld it perfectly square, the holes wouldn't have lined up and i would have never been able to get it bolted up. I told him to leave that section unwelded so I can rotate it as I see fit until the bolts line up. Quote Link to comment Share on other sites More sharing options...
Cam'ron Posted August 31, 2006 Report Share Posted August 31, 2006 oh ok... after you get it lined up properly you gonna get it welded? Quote Link to comment Share on other sites More sharing options...
stiv2k Posted August 31, 2006 Author Report Share Posted August 31, 2006 i'll think about it....it's much much easier to take the downpipe off this way, since earlier, the cat kept hitting the ground due to the curvature of the pipe...i never had enough room Quote Link to comment Share on other sites More sharing options...
mfewtrail Posted September 1, 2006 Report Share Posted September 1, 2006 I told you before that the stock piping was going to be 2'' diameter on there. Get your torque back? Quote Link to comment Share on other sites More sharing options...
Regal_GS_1989 Posted September 2, 2006 Report Share Posted September 2, 2006 That reminds me, I really need to get rid of the exaust u-bolts on my Regal. Hell, the entire exaust system is a hack job on that thing Quote Link to comment Share on other sites More sharing options...
terryk2003 Posted September 2, 2006 Report Share Posted September 2, 2006 so, was your old cat bad?...because if it wasnt, there is really no gain @ all from the high-flow cat... Quote Link to comment Share on other sites More sharing options...
stiv2k Posted September 2, 2006 Author Report Share Posted September 2, 2006 so, was your old cat bad?...because if it wasnt, there is really no gain @ all from the high-flow cat... I threw it out before I remembered to take pics, but the catalyst was broken in about 5 or 6 big pieces just rattling around in there whenever I went over bumps and stuff...I would say it was definitely shot.
