Even the crossflow systems will work to around 500 HP and no mufflers hanging under the car.

nothing cobbled together, it's all mandrel bent stainless from pypes. it would basically be their 3" kit but with 2.5" tail pipes. its about a 75% street car, will see track time but mainly for fun & tuning. just figured the 3" x pipe would be worth while & for the price savings just get the whole kit if it fits well. i know there are lots of firebirds out there with 3" full exhaust, hoping for some pics of opinions to help me decide.
