ok so i have a 2000 trans am ws6 ls1 6 speed, i already had a borla cat back on the car, and i just finished installing SLP long tube headers, high flow cats and Y Pipe. the car seems to idle and run smooth. so i took it for a ride to test out the new sound. under normal driving sounds fine and drives fine, so i tried to get on it a little and it back fires and falls on its face and if you keep it going it seems like a miss. i hooked up to my scanner and there is no codes logged.

does the full exhaust require a tune or an after market mass air sensor?

has anyone else experienced this after doing a full exhaust?

thanks in advance!
