  • JEGS Off-Road Y-Pipes for Trucks

    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, 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. Made in the USA.

    Rated 4 out of 5 by from great price, fast shipping. I bought this setup because of price and I wanted the straight pipe design. Overall I am satisfied with the quality and the bolt on installation. Depending on your specific application you may need to do some modification. I needed to do some tweaking to get the pipes mounted. And I needed to purchase additional adapters for the O2 sensors. Unfortunately there is a design flaw that had the O2 sensor bung that was pointed up towards the floor of my vehicle. Also where the pipes come together under the oil pan needed to be welded to get a good seal. All in all a great quality product but it is after market and does require some modifications.

    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 3 out of 5 by from good quality I had to drill out the holes on the passenger side flange at the manifold to get it to fit. Other than that it was perfect.

    Rated 4 out of 5 by from Good product, could have been better if I didn't have to modify two holes on the flange to secure it on the headers. Also, gasket was bent so I had to get another one of those. Could be better if there was a better way to secure the two pipes, the clamp didn't work the grestest, recommend welding it. Can't complain for the price though. Good product for the price.

    Rated 4 out of 5 by from fit pretty good, I had to drill out the flange holes on one side, one manifold stud was bent, get a better clamp, the supplied clamp is not strong enough to seal the 2 pipes together, over all I am very pleased with this product, would but again, plus fast delivery, I also picked up a few extra horsepower.

    Rated 3 out of 5 by from it fits bought this as a replacement for bad y-pipe. it fits as it should BUT the flange on the drivers side is NOT put on before the o2 sensor bung is put in place. had to notch flange to fit. lower o2 sensor bung is put in position where sensor hits floor boards. needs to be placed on a different angle.

    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.
