I recently purchased a 2010 C6 base that came with the corsa sport exhaust (judging this by pictures on the manufacture website compared with my exhaust) I did some searching and can't find an answer to my situation. Most aftermarket LTH and X pipes come in at 3". Anyone have the dimensions for the corsa and would I be able to use a 3" X to connect to the corsa? If this has been answered, I apologize, I have been searching for days with no answers.

For best performance and sound by all means go 3 inch all the way across and Corsa sport has no rivals.

You need to have a reducer welded in place or better yet clamped. A 3 inch at on end and 2 1/2 in at the opposite end.

Do it before the axle over pipes at the end of the mid pipe.

Best way is clamped then it can be taken apart.

And the gas have cooled enough by the reducer that it means little or nothing powerwise, a non issue.
