    Stock exhaust question

    So I had my '09 V up on the rack today doing an oil change and I noticed that the driver's side exhaust pipe from the front cat (where its bolted up) back about 18 inches is somewhat flattened out. The passenger's side is normal, perfectly round. Is this the way it came? It does not look like it was hit on the ground as there are no scratches on the pipe. I will try to get some pics. Thanks!

    Welcome to the crimped pipe club. Normal - they all have that, but don't ask me why. I am sure there was an engineering reason, but I don't know why.

    All the way back to my '99 Camaro that had it. It's probably older than that as I don't have a recollection of my '89's exhaust.

    They needed something visually 'wrong' to offset all the audible problems like the marble-in-can supercharger rattles, interior creaks and rear diff whine.

    Yes it's normal (or at least factory equipment), and ground clearance would be my guess for why the factory does this. If you look at both sides of the exhaust around the trans, there's not as much room on that side to tuck it up into the trans tunnel area, so making it a little flatter was the solution. I was surprised the first time I saw it also!

    I saw a used Borla system from an STS-V with full diameter piping that was crushed in that area from the car bottoming out on it over a speed bump or something.

    Thanks everyone for the answers! Now I know that it's normal, although I do not understand it.....
