Default What kind of clamp are you using on cat to header?

Using SLP LT headers (i know, bad choice) & thier high flow cats w/y-pipe. The cats are clamped on each end with the single bolt, narrow clamp that SLP supplies.

I've used 3" band clamps everywhere else, but I dont see how I'd get a band clamp around & tightened at the cats, especially the end attaching the cat to the header!

Anyway, I do get a small leak using the SLP supplied clamps, the leak is where the slit on the cat gets pinched and squeezed down.

So what clamps are you using around the cat to header? any pics would be great too!

I'd love to band clamp, but the area to be clamped: cat to header, there is no way to get a 3" band clamp around there, its too wide!

Unless Napa sells a 3" band clamp, but only 2" wide???

If I get the cats welded in place, I assume it'll be a real PITA if I need to drop the trans???

The area between the cat & header is about 2" wide. The band clamps i've seen are ll 3" wide, too wide.

So I'm looking for a style of band clamp that is 2" wide, or less.
Between 1 1/2" thru 2" wide would be perfect.
