*****All sets may be purchase with following upgrades both included for additional $50: 3" Stainless steel band clamps header exhaust clamps - for attaching y-pipe to headers instead of standard U-clamps (Does not crimp pipe and makes for easy removal and reinstallation after initial installation) & Multi-Layer Steel OEM style header exhaust gaskets.  4WD / AWD applications ARE NOT a direct fit (many people have modified them for fitment on 99-06 4WD / AWD, will not fit 07+ NNBS 4WD vehicles even with modification). No returns or guarantee of fitment other than listed 2WD applications. Any modification, scratches, damage or marking from attempted fitment on any application voids return or refund.

1 3/4" primary 304 stainless steel headers /w 3" collectors, 304 stainless 3" mandrel Y-pipe is included and is fully stainless steel and bolts right up to any factory or aftermarket catback exhaust (Single pipe).
Manufactured of high quality T-304 stainless steel with CNC mandrel-bent tubing, front & O2 sensor bungs installed. Add Instant Horsepower (25+ rwhp depending on other modifications and engine size).
We recommend using factory GM MLS exhaust gaskets and header bolts, O2 sensor wiring extensions recommended (not included).
Vehicles with factory 6.0L engines have dual exhaust that does not allow the catback exhaust following the Y-pipe to directly bolt up and require aftermarket single 3" catback exhaust required to fit.
