My trans am has alot of work done to it from the previous owner. He seemed to get the best parts for everything. He has no cats with 3 1/2 inch piping to rear with a horizontal muffler under the hatch with 2 pipes exiting. Is this a good exhaust for power? Its not really that loud, but it sounds okay. Its also edelbrock muffler. Should i upgrade to somthing else?

Also is it common to have the horizontal mufflers? I just go into f bodys and most other muscle cars ive had just had dumps at the rear wheels. Is this possible with an f body? Sorry if this makes no sense. thanks

 

Wouldn't know why not (I'm running a three-inch system with a cat behind my set-up).

Sounds like the muffler is in the OE position. You can fab most anything you want with some time and money.
