Darn new catalytic converter fits bad..

Bought this new converter to replace my damaged one but the 'in' pipe fits really sloppy on the down pipe that comes right from the motor... This is a 'bolt' on converter and it almost seems that one thickness of pipe could almost fit in between the two to snug things up.. Weird I just got this new from Qtec along with the new head/down pipe from Qtec..

I bought the EXACT same parts, and am having the exact same issue, I am just going to take it off and have a co-worker weld it instead of using clamps, I think that is our only option. It's good to hear that I'm not the only one with that problem.

Uuuggghhh!!!! I wish they would work for what they say it works for... Damn..

The only other thing for a home garage with no welder is to take a short section of pipe that is the inbetween diameter and fit it in between but that might be a needle in a haystack. Maybe an old style steel Stroh's beer can?

You can take out the cat, and the head pipe, and take it down to a local exhaust shop, or even a machine shop, and I bet you could get it welded for pretty cheap.

Yeah, looks like the best thing to do... Make sure you have the converter marked (sharpie?) as to how it is clocked on the other pipe.. Otherwise it might be at funky angle and hit the underside creating a bad fit.. I am just mad that they are not perfect together.. What the &^$*&*$(@))))%$@!!_()!!!!f is up with the converter company??

Alot of guys here are running them, so a bad run of them maybe? Ours are the first complaints that I have seen on this.

The head-pipe end is a little loose, the muffler end fits fine.

If you can get it on there temporarily to just make it to a muffler shop they would probably weld it all up real cheap....this would be better than taking just the parts to them for the fact after its welded off the Jeep it may not fit well.

About 2 years ago we went down to Fla where my cousin is based in the Air Force for Thanksgiving in the Jeep and my exhaust cracked and cut loose right before the cat converter,since my cuz had no welding gear,i took it to a local muffler shop and they welded it up for a whopping 20.00 for me.

Mine was the same....almost a 1/4 gap until the taper end....I stuffed it in and threw the clamp on...been tight with no leaks....

I might stuff the gap with some JB weld..

Did anyone get the Dynomax catback setup? In the photos it shows the offset pipe being the in pipe but the only way possible to mount this is to have the centered pipe as the in pipe and the offset as the out pipe.. Does it matter which way this goes?

I installed it...The offset goes to the rear..ie tailpipe...

I contacted Magnaflow today and the told me to do a warranty exchange on the cat...They asked for the date of manufacture on the box..maybe they can track down what is wrong. I hope the new one I get is the proper diameter inlet. All this down time is killing me, my Jeep is torn apart in the garage with the skid plate off and no exhaust..
