im lookin for a stock 87 downpipe in good condition for cheap. my crappy downpipe is hitting the header in 2 spots, its hitting the frame, and its hitting the crossoverpipe. its making my car knock up to 15* with only 3/4 throttle and 15psi of boost. if i give it half throttle it pulls pretty good. over half, the computer starts changing the timing and it feels slower than 1/2 throttle. my o2s are at 800 at 3/4 throttle. im scared ill blow the motor if i go wot. i dont have 500 dollars for a downpipe i just want to be able to run it this year. if ya got a downpipe or any suggestions let me know.
