I want to get two cut outs somewhere on the y-pipe pictured below. I was thinking somewhere before it merges into the I-pipe. Would it be benificial to do this, or would it be the same if I just got a single one on the I-pipe? Any input appreciated!

 

If I had to venture a guess, I'd put one after the cat where it starts curving towards the I. So the idea would be to have a straight shot out from the cats. It'd be totally rocking if you could put them before the cats though.

 

Personally I'd go before the cats but if you want them after the cat's then like ShadowLightCSU said and a strait shot out of the cats.

 

I wanted to put them before the cats, but I don't have enough space between the header and the cat.

 

Anyone else? Pls? I am doing the install tomorrow.

 

I'd get crazy with it, see if you can have an exhaust shop cut the ypipe, move the cats back a bit install the cutouts before the cats. Not sure if it would make the cats run too cool though if you moved them further back. You could also just o2 simm the rear o2 sensors and delete the hole when you move the cats back.

Sounds crazy, but would SOUND AWESOM
