I'd stick with the tailpipes, definitely. I used to run with turn downs and 2-chamber Flows...and it was obnoxiously loud. After getting a ticket for not having cats (damn motorcycle cops!)...I decided to put the tailpipes back on to aid in keeping the law off my back. It's quiter, but actually sounds better now! And boy, what a difference! So much more torque! I don't know what I was thinking when I didn't put them back on after my motor upgrade. Young and dumb, and loved that loud rumble I guess. I've also heard that Flowmaster, along with some other aftermarket muffler companies, recommend at least 18 inches of exhaust pipe after their muffler to obtain maximum horsepower gains on '86-'93 5.0s. Something to think about...
