I ordered a new exhaust system on-line and one of the pipes came in w/ what I thought was damage. When I contacted the vendor they said those were normal tooling marks and the pipe was supposed to be that way to fit the car. The other side was perfectly normal - no deformation at all.
Yup that is normal. That is why I had a custom system bent up. Mandrel bends and no flattened pipes. If your not running a high HP motor those pipes will work fine. If you are looking for max flow get a custom system bent up.
Original Corvette exhaust was somewhat flattened where the pipes went under the differential to provide more ground clearance.
Is that what you are showing?
It's over a wider area than just near the differential and only on one pipe. That's what I thought was weird.

They're 2 1/2" on a mildly built 350. I'm sure they'll be OK - just wondering if it was normal.
Thanks to all.
