Hey all whoever has the corsa exhaust since it is a 2.5 inch piping is there anything special that needs to be done to make it fit?? i mean i know its a bolt on but still i have never done an exhaust so im wonderin

 

Stock exhaust is 2.5" (why I think its a waste), why would there be a problem with fitment?

 

it aint 2.5 haha why would the gmpp exhaust be 2.25 and then stock be 2.5 stock is 2.25

 

oh my goodness people... the GMPP Exhaust is 2.25" WITH MANDREL BENDS which means it will flow better than the STOCK 2.5" with CRUSH BENDS.. The CORSA is 2.5" MANDREL BEND which probably flows more like a 3.0" CRUSH BEND.. Stock is 2.5" till it gets to the rear axel and then narrows down to 2.25". Install is a breeze with the Corsa. You have to cut the stock exhaust pipe BEFORE the rear axel. About 7 inches so u can remove the old exhaust

 

Maybe I got some kind of experimental car, but my stock exhaust was 2.5" mandrel bend, it was definatly mandrel bent, the muffler shop that did my exhaust even said it was mandrel bent and that it was weird for stock cars to have mandrel exhaust. It still had the 2.25 section though.
