Not too bad

Summit RacingSummit Racing Verified Purchase

Not too bad of a kit, main pipes fit well, rear pipes over axle needed some re-bending to fit correctly but overall not a bad kit for the price

Used on 1982 k20.

Summit RacingSummit Racing Verified Purchase

Great kit for the price. Had to modify one of the angles on the drivers side head pipe. And expand both the ends to fit my collectors but I also used Summit Racing headers so... Only other thing was the tail pipes aren't bent to the same angle so there is a little difference there. All in all, considering the price there is no reason to complain. I would use this kit again, no doubt in my mind. ...read more
