Default AccuSeal Exhaust clamps...anyone used them?

Anyone here have experience with the "AccuSeal" exhaust clamp:

Is it any better than the old U-bolt / shackle design?

That'* the same type of clamp some aftermarket headers use on the crossover. Much better than U-clamps. They clamp almost all the way around.

But I'd still use some sealant in between. Welding is still also much preferred.

Will,

What sort of sealant?

Unfortunately, what I want to do can't be taken to a welding shop, due to my geographical circumstances

Use the muffler sealant that is water-activated. Smear it on, push the pipes together, and work a little more in the end of the joint with your finger, then clamp to spread it and squeeze some out.

It'll cure with the exhaust heat.

Andrew..I have those on my headers as part of the kit. So far..I've loosened and retorqued them 4-5 times in all when swapping over and doing other work They seal great every time. My opinion on sealant is different, don't use it unless you must, that way if you need to get the pieces apart they will come apart easily.

Muffler sealant is easy to remove and clean up later.

I wouldn't use it on the crossover for headers, but I would downstream at each component.

Those clamps work awesome. They come factory on BMWs, Jaguars, almost every turbo diesel truck, etc. They make it very easy to dissassemble the exhaust or remove pieces as necessary to service the car. Especially when these import tuner morons run their exhaust right under the gas tank and you've got to change the pump! :P

I have one on my Buick where the Downpipe meets the dump pipe and I have the DP in and out numerous times and get a perfect seal every time I put it back in. They work great and don't damage the pipe like the u-bolts do, I am surprised these are not more widely used!
