to buy the roush exhaust from the roush store....or juss go to a muffler shop and do it that way....

 

i would have a shop make it.....i love custom work versus store bought stuff

 

custom work would be a ton cheaper. it is actually really easy.its a pipe back to where the stock gt mufflers are then you have to have a same side in out muffler and the pipe just comes out there and out the side.

 

yeah ivote for custom work too...cheaper is a plus wnyway
