I just purchased a 65 4-door Wildcat with a 401. It needs exhaust and it currently does not have a dual set up. I know this question has probably been asked and answered a hundred times, but what kind of mufflers/resonators do you recomend for a more aggresive street sound, and where is the best place to get such a system.
I have a dual 2 1/4in exhaust with Flowmaster 40's. It's got a good rumble and isn't overly annoying. I think you can get a replacement factory system, and then modify it to fit mufflers of your choice. I have the name of a guy I'll have to try and find.
