They allow the installer to custom-tailor these exhausts to fit vehicles with non-OEM aftermarket headers. They're made from extra-long, 16-gauge aluminized steel for lasting durability, and the tailpipes exit out the sides. All necessary hardware and instructions are included for a complete installation. Mufflers are not included.

k 20 exhaust

Summit RacingSummit Racing Verified Purchase

Not too bad

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
