Speed Engineering Headers - Adding cats
Has anyone tried adding a high flow cat to a set of Speed Engineering long tube headers and y-pipe? For $400 headers and y-pipe and a $100 for a cat, I'm willing to do some hacking on these things to make it work but didn't want to reinvent the wheel if I didn't have to.

Be prepared to have flanges welded in or at least weld the short section of the Y pipe that slips together and then do the aluminum foil wrap with the 3" band clamps or you're gonna have a lot of leaks. That's my only issue with the headers.
Oreilly sells the 3" clamps. They are in a flat package and they do not have a step in them like some band clamps do. Those worked best and my buddy that's ran a muffler shop for 20 years said he's had the best luck with those, so far they are working better for me than the others i've tried.

I’ve got a welder. I don’t make pretty welds but they don’t leak and that’s all that matters. It’ll be a while before these go on as I’m going to send them to jet hot to get coated before install.
