I need to get some mufflers and stuff put under my '83 GT. Currently I am running long tube headers and glass-pack (PO) that dump about under the seats. I have tailpipes off a '86 GT that I want to use and am thinking of running Flowmaster super 44's. So my question is what orientation of the mufflers do I need, offset-offset, or offset-center. And how was the system routed from the factory, I have a feeling that it ran in the driveshaft tunnel and stuff.

Also is there anything I need to look out for when putting the dual exhaust system under the car?

Thanks in advance,
