I bought my 02 gt with flowmaster mufflers welded in, it actually sounds decent but I want to change out the stock mid pipe. where can I find which mid pipes(X) are compatible with what cat backs eventually will buy a cat back

 

Any midpipe will hook up to your catback. I'd go with an H pipe instead of the raspy X, but its all a matter of opinion

 

not short midpipes...

 

Oh yes they would. He's not talking long tube headers here so they're out of the question.

 

Thanks for the info I"ll look into a new H pipe I was thinking that certain brands would not match up with others

 

I've never swapped out my midpipe but they all hook up to the stock catback, otherwise they wouldn't sell them.

 

Just dont get a shorty midpipe.

It will literally say "SHORT H PIPE" or whatever DO NOT GET THAT Get the regular midpipes.

 

Yep, that would not be good.
