Quick muffler question: I'll be getting Flowmaster super 40 series mufflers to fabricate for my exhuast, but what do you reccomend? One or two mufflers, since it will be dual. I want it loud and beefy, so that's why I'm sticking with flows.

When I took my mustang to a muffler shop, they put different mufflers on to see which one I liked. In the end, I decided to go with the flowmaster series 10. It was louder than a dual series 40 and had a nice popping sound. I paid $390ish total.
Stangfanatic98 said:There's a great idea. I sent my inquiry to Springfield Motorsport..that's my first mistake. Anyway, I still can't find flow's for under $80-100 each. Anyone know of good places to look for em'? I've tried google but every website i so expensive..even when I try 'discount' and 'sale' etc etc in my search query. I don't trust buying car parts off e-bay however. So I guess I'll hold off on buying that MAC flowpath bolt-on for now. its only $230 and labor is free since its a no-brainer.![]()
