Don't think Corsa Touring kit will fit, only for Corsa applications. Stock H pipe is fine, the X-pipe sold by WCC should work. I'm sure others will supply input on the +/- if any regarding X vs H.
supposedly according to corsa a few hp the main reason is to get rid of the popping on decel. Also deepens the exhasut note and shifts the torque curve slightly towards t he midrange
Suggest you contact Flowmaster & ask for their recommendation. Might be difficult to mix & match exhaust pipes with muffllers unless they're designed for each other (length & pipe OD/ID)...unless you like to do cutting & welding.
I would tend to think most X-pipes are the same dimensions, in that they replace the same H-pipe, and all (most) of the catback systems are designed to work with the H-pipe or their X-pipe. Verification with manufacturer would be best though.
If you really want one, I have one from my Magnaflow system that I'll sell you for 1/2 advertised price + shipping (which should be around $200 total). I went with headers and 3" X-pipe w/cats.
