Now I've pretty much decided that I'm NOT buying another carb, re my previous thread, I've decided the car is much more in need of a new exhaust system. I finally have had enough of the Flowmaster 40 drone, time for it to be gone!!
I'm hearing good things about the new Flowmaster FlowFX straight through on other types of vehicles, but I'm wondering if anybody has installed a pair on a Mustang 351C 4V with stock manifolds? No, I do not want to go to headers!!
I may go to 2.5" pipes, which will be custom made, a) for cost and dollar exchange benefits and b) to support our local custom exhaust shop. If I go 2.5", I may need to open the outlets on the manifolds to 2.25" as is the Boss stock manifold, or I may just stick with the 2.25" that the car came with and save myself some work.
So guys, anyone have an honest opinion? Lots has been discussed over the last couple of years about mufflers and drone, but by all accounts these new FX mufflers do not produce any drone, which is the main goal...……. but with a nice sound.
