Exhaust Band clamps vs. Welding?

I'm currently purchasing 304L Stainless Steel tubing to go with my muffler and cat. I do not have the capability of welding 304L Stainless Steel.

I was curious if the clamps below are acceptable, or am I better off taking the system somewhere and getting it welded? It would be nice to be able to replace the muffler or cat without cutting, but if it's the better of the two, which I assume it is I'll do it.

Band Clamp

Band clamp 2

Any info or other advice would be great!

Ryan

How perfect do the ends have to match up with those clamps?

I have no idea, I assume as long as it's the same size tubing and they are not burred up or uneven they should be ok?

I was looking at V-Band clamps, but they require welding.

If there are other manufacture's band clamps that may be better than others I open for suggestions.

The clamps you show, allow the two exhaust pipes to slip together. The seal will be better than the crush style. The band clamps are stainless and look great. One added plus factor is later on you may want to make changes and thats just a wrench away from making any change. Go with the band clamps. One last thought on welding - how good is the installer? Crappy welds will take everything away from a neet install. TF

The stainless clamps I recall using in the heavy truck fleet, were ones that came with those same ends. but they came as a flat sheet without the step. Because the heavy end pieces HAD the step machined into them, the flat band would actually make it's own step as you tightened it. It stretched the metal for a super tight seal to any irregularities.

Here are some more pics of the clamp, looks like they might be ok after all:

Band clamp 1

Band clamp 2

Band clamp 3

Thanks for the adivce guys. If I decide to find a welder, I will ask to see some samples prior to letting them do the work. I think I might have to get the reducer welded.
