Greetings!

I have been considering getting a tune for my 2004 Mustang Gt and noticed that I need to send in my information about my exhaust system. I know that I have Flowmaster mufflers, but I am unsure whether I have an aftermarket H pipe and/ or catback. Can someone please take a look at these pictures and tell me what they think? Thank you for the help. =D

 

Best I can see is that everything looks stock. So if you know you have the mufflers I would say that everything else is stock.

 

Looks like the mufflers were just welded in and the h-pipe looks stock as well.

 

Thanks for your help everyone!
