I'm thinking about making a custom cat back for my car, but I need a good I-pipe. You can buy I-pipes from Dynomax, but I don't know if they're just stock replacements. There is one that they make which looks like it's for the 2OTL exhaust, it's 3" and on there web site they say all they're pipe is mandrel bent. So I was wondering if anyone could tell me if they make good I-pipe or if there is another option for a good I-pipe.

Thanks

hey man I think you mean Y-pipe. Have never heard of a "I-pipe"

 

I-pipe is after the Y-pipe. Its the pipe that goes over the axle.

 

okay my bad. I didnt even know there was a name for that pipe. sorry!

 

dude the I pipe can be made at any exhaust shop for next to nothing with any diameter pipe you want. get a y pipe and a cat-back and get the shop to connect them with 2.5" or 3" pipe

 

Ya, they can bend the I-pipe, but all shops around here press bend the pipe and that decreases the diameter of the pipe, and I wanted a mandrel bent I-pipe so it would stay the same diameter throughout the whole I-pipe.
