I have flowmaster 40 Series mufflers installed and about to put on a BBK off road H next weekend. Is there any side exhaust system that will work with this system? I have a 96GT
You would probably have to have a set of pipes custom bent for you, if you want to use the same mufflers. You can always just put the o/r h-pipe on and then get the side exit Borla cat-back installed. Spintech also has a side exit exhaust system. But if you just want to use the Flowmasters, get a shop to custom bend some pipes for you.
I bet it would very greatly from shop to shop. Personally, I would only let a performance shop or a shop that specializes in performance exhaust do something like that to my car. If you have a local Mustang forum, ask around there to see who would do the best job at the best price. I'm sure someone there could give u a better answer than I could.
