Need to Cut Welded Y...Ideas??? Back when I first started modding, I had my Y welded up to prevent leakage and fix mistakes from a previous exhaust shop. Yeah, it was a great idea then, or what I thought, but now, probably would change my mind on the issue. Now in my h/c swap, I need to drop the headers, but the whole system is welded all the way from header back to just before right over the rear axle.
I have determined on where I can possibly cut the Y just after each header to successfully drop them and keep the rest of the exhaust in tack.
The full exhaust is 3" to the rear with a flowmaster merge bringing the Y together.
What I am looking for are ideas on how to rejoin the 2 cuts so that I can get the exhaust back together without welding......heres what I'm thinkin.....
I saw the some exhaust flanges that have a 2.5 ID and 3 OD. This seems like a possible fix, but not to keen having the exhaust bottleneck from 3" to 2.5" back to 3" right in the middle of the Y.
I also have (2) 3" band clamps, can I cut the exhaust, do what I have to do, then rejoin with some exhaust wrap and band clamp them together?
Once the headers are on, and the I-pipe reconnected to the over the axle pipe, the Y will be lined up with the headers and there is no room for play or movement. Shoot me some suggestions if have some.....other than get a new Y pipe or exhaust, just need some diffrent angles to fix this, thanks guys

If I were you I'd just cut the y like you described. As for reattaching it, take it to Jamie and see if he can weld in some 3-bolt flanges so that it won't leak and is removable next time.

Have v-bands put back on. That way you'll have a leak free connection and will be able to dissasemble it very easily and quickly next time...I'm building my true duals using vbands. Nothing better IMO

Thanks Mike, I will probably just do that, he fixed all my exhaust problems before and had him weld it up. I might just band clamp the cuts for now, get it to Norris to be tuned, then get to Jamie for the complete fix with 3 bolt flanges.
Oin8io...what are Vbands, I'll search and see whats up with these?

Ahh yes, V-clamps...Band clamps, yeah I have 2 of them I was going to use to rejoin where I make my cuts. I have already tested them and this helped me determine where to cut. Looks like this will be the plan for now, full speed ahead when I get home tonight. Thanks guys.
