which band clamps to get? (pics)
one is from jegs, other is from summit

The bottom ones have always fit excellent and seem to give a tighter seal.

i actually couldnt get one to seal on my custom y pipe, and the jegs (formed) clamp worked great.
good luck with either, you cant go wrong.
I have some of the top ones on order. I will try and post back to tell everyone how they work. If they dont work any better than the flat oones then I will be welding me a 3 bolt flange in place of the slip fit joints.
the NAPA ones WILL require 2 wrenches.






got mine at napa...worth it here as well.
