Exhaust options

[DallasHannah3]

Hey guys, I drive a 70 nova with an 83 305/TH350. Right now I have a 700cfm (late 70s model non-ecm controlled) rochester qjet and dynomax blackjack headers w/ 2 1/2" collectors. I am planning on running glass packs where cats would typically go on a car and then i want to put either an Hpipe or an X pipe.

My question is... do X pipes flow better than H pipes? Does 1 outflow the other, does 1 provide more torque than another or is one more for horsepower?

I'm going to run about 1 ft of pipe from the collectors, into 2 glasspacks, then into an x or h pipe, then run it back over the axle and into dual turbo mufflers...

I wanna figure out which is better. This is a street strip car and is used daily now, but will be a weekend cruiser (still used on the highway too) in a few months.

Thanks for any help/suggestions

Dallas, install the H or X before the glasspaks, right after the collectors. Here's a copyrighted piece from autoMedia.com Inc. explaining the background of the device.....
