    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 4.2 out of 5 by 18.
    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.

    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.

    Rated 5 out of 5 by from y pipe great quality and quick service. the place to order y pipes.
    Date published: 2015-09-13
    Rated 4 out of 5 by from Only one thing I installed this on my 98 Tahoe everything lined up great.. Except the down stream o2 sensor for the right bank. The heat shield rubs the top of the sensor...other than that it is a perfect fit...
    Date published: 2016-11-17
    Rated 4 out of 5 by from better than expected Pipes fit very well. The flanges however did not. I had to open up the holes in all 3 flanges. The manifold flanges were slightly off ( increased hole side 1 bolt size bigger, then the fit very nice) and the muffler bolt flange holes werr off a bit so i had to increase the hole sizes to 1/2" and used some washers. Over all not a bad product .
    Date published: 2016-11-06
    Rated 4 out of 5 by from great value for cost Installed about a month ago. Exact fit. rear o2 close to floor board but you can adjust pipes at the end if you leave nuts loose. Could use better quality band clamp instead of cheap clamp. My gasket was crumpled up also.

    I have some pacesetter shorty headers that have 2.5 collectors. Would these fit into them?

    Asked by: obschevy
    As long as they are for the applications listed with this part.

    Will this work with a 2 1/2" catback system? The description says it'll work with 2 1/4" aftermarket but mines 2 1/2" . Also will I need o2 sensor simulators and 90° adapters

    Asked by: jjmccloud
    A 2.5" cat back system can be attached to this y-pipe, we do not offer a 90 degree o2 adapter.
