My car is street legal. It's mainly used for drag racing.
If I ran my exhaust without a h-pipe, would there be any loss in racing performance? Right now I have shorty headers, H-pipe (not sure if it's stock or aftermarket), cat's, Flowmasters. There's an exhaust shop in my area that does some quality work. I was going to eliminate the H-pipe so I can have more up and down clearance for my driveshaft loop. Also, I need more left to right clearance on the mufflers.
I was going to have them do a true dual exhaust set-up with some exhaust cut outs welded in after the headers(so i can run open exhaust at the track), then the cats, and the Flowmasters.
I may put some long tube headers on, but I'm not sure if there would be that much of a performance difference with this motor at the moment?
My motor is a Ford Racing 302 345hp crate motor with the b-303 cam. Rpm operating range is 4000- 6000.
Thanks for the help!
 
Well eliminating the cats moves the torque curve up slightly, so you'll gain top end HP but lose some low end torque due to the shift.

Also you might want to consider having the crossover welded in to keep the "H" configuration
