  • JEGS 31005 Details

    GM

    • Fits all to 8500 GVW with OE dual 2" exhaust after dual converters only.
    • 2-1/4" inlet and outlet with dual flat flange connection will accomodate factory 2" dual exhaust or aftermarket 2-1/4" dual systems.

    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.

    31005 - JEGS Off-Road Y-Pipes for Trucks is rated 4.1 out of 5 by 27.
    Rated 5 out of 5 by from Good quality. Like everyone else said you will have to drill out the holes for the manifolds. I really hoped after all the complaints about that it was fixed. But it wasn’t. Also use a different flange gasket. The supplied one failed immediately. After you get it fitted it wouldn’t be a bad idea to get the crossover pipe welded. I found it difficult to stop it from leaking. Would buy and recommend again.

    Date published: 2017-12-11
    Rated 5 out of 5 by from Exhaust Y pipe Purchased about a month ago had a chance to install it yet. But if it fits anything like the one we got for my 96 ram it will be perfect.

    Rated 5 out of 5 by from Good product, only minor issues. Happy! Bought this for a 1999 Tahoe 2 door. Fit was almost perfect. Like others have said I had to "drill" out the holes in the flanges to get them to go over the manifold bolt heads. The downstream 02 sensor bung on one pipe is indeed at a bad angle and puts the sensor right against the bottom of the heat shield so in order to use the non-foulers to fool the o2 sensors I used a 90 degree adapter (ebay) and it works great. Very happy with the price and the obvious slight Performance gain. Definitely a much better flow than the puny stock 1 7/8ths downpipe. Also the sound is much throatier sound. Would buy again.

    Rated 5 out of 5 by from It fit great and solved my exhaust noise problems This product fit well the only issues you will have is the flange bolts at the manifold must be drilled out to fit the studs. You will also need 90 degree O2 sensor extensions for the down stream O2 sensors to keep it from setting the check engine light and throwing it into limp mode.
    Date published: 2016-04-13
    Rated 5 out of 5 by from Great set of pipes for your off road pickup This set of pipes fit my 93 K1500 great since I was starting from scratch and built the rest of the exhaust myself.

    Will this fit a 97 5.7 vortek 4x4? And will it fool the 0xygen sensors?

    Asked by: Red2006
    This will fit the Chevy truck, and each system is different on how the Emission equipment will respond, but this is for off road use only.

    Does this have the other downstream o2 sensor bung or just the one? If its just the one what do i do with the other sensor? Also will it work with a 3" cat back kit?

    Asked by: KParsons76
    This kit has provisions for 2 O2 sensors. You can connect a 3" cat back kit to this kit.
