    GM

    • Fits all with OE 2-3/4" single flat flange exhaust after dual converters only EXCEPT 2000-2002 OE y-pipe systems with flat spot after driver's side O2 sensor and just before the y-junction
    • 2-1/2" inlets and 3" single flat flange outlet will accomodate use of factory 2-3/4" exhaust or aftermarket 3" system.

    JEGS Y-Pipes provide maximum exhaust flow for off-road truck use. These fit directly from the manifold to the stock cat-back exhaust for all 2WD/4WD applications and wheel bases. Constructed from mandrel-bent 16-gauge aluminized tubing or 409 stainless steel, the pipes include flanges, gaskets, oxygen sensor bungs and plugs, and exhaust clamps. A JEGS cat-back exhaust system is recommended to receive the full benefit of the increased exhaust flow. Catalytic converter(s), sold separately, can be added for street-legal use, yet some modifications will be required.

    31004 - JEGS Off-Road Y-Pipes for Trucks is rated 3.4 out of 5 by 5.
    Rated 5 out of 5 by from Perfect Got this for a twin turbo build on my 2003 Silverado and it fit perfectly.
    Date published: 2016-10-29
    Rated 5 out of 5 by from great product I've used this y-pipe on several GM trucks, it's easier and cheaper than having a local muffler shop cut the cats out of a factory y-pipe.
    Date published: 2014-12-26
    Rated 4 out of 5 by from fits great on my 06 4x4 Nice flanges and bends, but do yourself a favor and order a 2.5" band clamp or just weld the crossover pipe. Don't even try to use the u clamp or it will just cause an exhaust leak.
    Date published: 2017-08-29
    Rated 2 out of 5 by from Comes up a little short. Bought this for my 02 Suburban with shortie headers to accommodate my 6 inch lift because long tubes would not work. Good thing its a 2 piece assembly because it came up really short on the width in the center. Had to put a spacer tube in the middle of it to make it work.

    Rated 1 out of 5 by from Looks nice Bought it to replace my y-pipe and got it bolted on and it did not fit my truck like the listing says. Leaked out of the 3 bolt welded flange side, hit my transmission on the passenger side and the 2 bolt flange at the collector was not deep enough to seat properly with the rest of the exhaust. Do not recommend buying on.
