"H-pipe," X-pipe," or no pipe?

Bought the TTI system in 99, with dual 3inch pipes, Dynomaxers, and their simple H-pipe crossover. Drove it for 4 years or so. Had to sacrifice it when I put the GearVendor in it.It seemed like I lost a ton of torque.From right off idle to maybe 2400 or so rpm. But it sounded better, to me, out the TP.I put 4.30s in/problem solved. 4.30 x .78 = 3.35 final-drive. That was fun for a summer or two. Then, eventually, I put 3.55s back there. 4.30s suck with a 3.09 low, on the street;(4.3 x 3.09= 13.29starter gear. Sounds like a doggone Mustang 5 spd. Sheesh)
Sorry, I digress. I vote crossover. Any kind. Whatever your budget allows. Extra torque,off-idle, is always welcome in a streeter.
