A buddy of mine, just had his 99 Trans Am dyno'd today. It has Mac midlength headers, ORY, and a SLP Loudmouth catback. Other than that, and a shift kit, the car is stock. It made 324.4rwhp and 344.9 torque. Isnt that a bit much for a Exhaust only car????

Seems about right to me. Remember, the HP and TQ#'s GM put out wasn't at the wheels, they gave us engine power.

I dynoed my 99 ta the day of my graduation in 102 degree weather with a lid and a cutout and otherwise a stock car and made 300hp and 303ft lbs.
