found some band clamps from jegs.com for these pacesetter headers. question is, do i need a 3" clamp or a 3 1/2" clamp? I know the pipes are 3 inches but at the joints its a little bigger, so which one do i need? thanks fellas

 

3" is what I used on my LPP's with 3" collectors and slip fits.

 

so im guessing these band clamps are what you can use instead of welding the y pipe and such together?

 

Well you wouldn't weld the Y pipe to the headers you'd use one of the various clamps to make them seal properly like v bands, band clamps, and what most headers and Y's come with those shitty horseshoe looking clamps.

 

if its a slip fit y-pipe youre going to want lap-joint band clamps. they have a little step in them, one for the larger side of the pipe and the other for the smaller.

 

yes. these are the ones ive found

3"

3.5"

If the collector is 3" you want the 3" band clamps.

 

The Y-pipe on my StainlessWorks set up doesn't use the lap-joint style and it's sealed perfectly
