Hhr ss catback differences

Hello. Does anyone know what is the difference between manual transmission and auto transmission stock catback sistem? The part numbers are different. Trying to find out if I can use stock manual trans catback on my ss auto. Thanks.

The manual transmission engine is placed back 1 inch then the automatic.
The manual has a different baffling then the automatic, but that’s the OEM muffler.

Yep, that smarty beat me. Engine position. So pipe lengths are different.

He is an old friend, that Smarty...
