i got the bonez cat from rx-7.com, but i noticed that the air pipe doesn't have a flange like the stock cat does... did you guys have to weld on a flange to connect the pipe? or what did you guys do to connect it?

 

^bump...?

 

Ummm...which one did you get. I have the full bonez exhaust (the 50mm exhaust and the superflo) and my cat has a flange, i just had to cut the stock pipe shorter (they tell you that) and use a hose (and clamps) they give w/the kit. You might have a different one though...did you just buy the cat?

 

yeah only the cat, no instructions whatsoever, but they did give me a rubber hose and clamps
