    No bigger than 3 inch pipe per side. An X pipe is traditionally a horsepower maker, and an h pipe is more along the lines of torque gains. Either will equalize the exhaust system and work well. cutouts as close to the collectors as possible. Use mufflers and carry the duals over the rear axle and out the back, otherwise it is obnoxiously loud inside the car.

    you can put the mufflers before the axle if you want, my suggestion is just to have the setup exit at the stock location.

    Its the same as an LS1. Here is a 97 SS with shorty headers and TD's.
