Does anyone on here have this set up? I really like the sound of the Corsa and their price is really comparative to other brands. The thing that gets me is I saw they are advertising it at 2.5 inch. Why would they make a system that has smaller piping than the factory exhaust? Can anyone confirm the exhaust piping size for this system?

 

A part number or where you have been looking would help...

 

If it is a smaller diameter pipe, then it will add to your low-end torque curve.

 

I'd like a part number, too. All I found for the 09-10 was the DB version.

 

it's 3''. stock is 2.5 ID
