Understandably, welding your y-pipe to the header collector will eliminate exhaust leaks at that place, but nobody is stupid enough to agree to doing that. Any tricks out there for successfully sealing exhaust leaks at the band clamp? High temp RTV, exhaust repair tape, let me know whats worked for you.

Why is it stupid to weld the y-pipe to the collector? My x-pipe is welded to my header collectors. You want to eliminate the problem, then that's the way to do it.

Cut and weld on ball-and-cone connections.

I used high temp rtv around the band clamp, used a impact wrench to tighten the clamp and 2 years later still no leak.

I agree. However, I would try to avoid welding the exhaust manifolds/headers to the y-pipe so you can remove the heads if need be without getting it welded again. But if it leaks there repeatedly, screw it... a $40 weld job is better than haggling with bolts and clamps repeatedly in an effort to avoid leaks. But opinions are like

Lap joint band clamps.

get the wide band clamps , i think they are 3" wide , smear them with red rtv and tighten them down with an air tool till it stops moving . Works on my brothers kooks true duals and worked on all the rvs, buses and motor homes he worked on .

Lap joint band clamps... but overlap one piece of header wrap on the seam before installing the clamp. Works very well.

This. I used these Walker brand lap-joint band clamps from Summit. They have a dab of glue or something in them to make sure the joint seals. They're pretty nice, but about $9 each.

I currently have the lap joint band clamps on the car now and have tried the RTV trick before. I suppose the next step is to try some header wrap or similar under the clamps with added love by an impact gun. Thanks guys.

I purchased V-bands and had those welded in. Big improvement.
