damn good actually,i fixed my distributor, so CEL went off, and its running off all 4 cylinders now, shes pretty quick. i can deff feel my straight pipe now, it still smokes at idle tho, not sure why, i think its because of moisture that gets into my exhaust, (i have a leak in the middle of my pipe) and it smokes. It smells really bad to since i dont have a cat. Hows yours comin man
