Headers for supercharged 302?

I am running a '68 Mustang convertible w/ a B&M blower and Holley 700 double pumper. It has a mild blower cam w/ tri-y headers into a 2 1/2" exhaust with an x-pipe and Dynomax Super Turbos (the Flowmasters were too loud and droned). C-4 trans, 9" Detroit Locker w/ 3.70 gears and Crane ignition. It runs like a banshee on the street, but I'm wondering if the tri-y headers are hurting me on the top end at the track. It has tons of low end torque, but seems like it's not making all the power I think it should be making on the top end. It runs 13.50's at 100 in street trim. Would long tube headers make a difference on the top end and what would be a good header to go with? This car is very quiet which I like because nobody suspects what's under the hood. The sneakier the better in my book.

I've often wondered about this myself. Ideally, a supercharged car should have four individual pipes, no collector. This would obviously collect all cops without a sense of humor. I would say the 4 into 1 would be better than the tri-y.
