Engine 2013 Gt ?'s

Hello, we bought a 2013 GT last night. It has a full exhaust from the headers back, says JBA on the headers and Magnaflow for the mufflers. It's loud!
Anyway, there is a gas smell, could that be an exhaust leak or something else or is that normal for that mod?
I'm going to have it looked over by a mechanic next week, we got it in writing if anything is wrong we can bring it back.
Anything else I should look for?

Thanks

Thanks for the reply.

I had the car checked out, nothing wrong with it.

Thanks again for the reply.
