    31006 - JEGS Off-Road Y-Pipes for Trucks is rated 3.7 out of 5 by 6.
    Rated 5 out of 5 by from Great fit and very fast shipping I bought this y pipe a little over a month ago. Fit my 1998 k1500 perfectly and shipping was incredibly fast. Very happy with the purchase.

    Rated 5 out of 5 by from Problem solver Reviews of needing to redrill flanges made me nervous ,but installing to a set of JBA headers went well. Their hardware fit perfectly. It's only when installing to factory manifolds that the flanges wil need redrilled slightly to 7/16" for the GM studs already installed in manifolds.

    Rated 3 out of 5 by from Not a bad y pipe for the money but the flanges and donut gaskets could use a little more attention they are cheap but the system isn't to bad for the $

    Rated 3 out of 5 by from Decent quality, not an exact fit I decided to buy the stainless version of this y pipe for my 1998 Chevy k1500 with dual cats and pre and post cat o2 sensors on both sides. The pipe was very hard to line up to the flanges at the manifolds without misaligning the end at the three bolt flange. I ended up having to drill out the holes on the triangular flanges in order to be able to slide them over the manifold studs. Would recommend replacing studs/nuts on manifold.

    Rated 1 out of 5 by from Horrible Well, this was the worst fitting piece of exhaust ever. The holes for the flanges were all wrong. I had to elongate them all to make it work. After that, the flare for the donut on the smaller piece wasn't flared enough to even start the nuts. So after flaring it more, I got it partially installed only to see that if they were in the correct position on the manifolds, when the intermediate pipe was installed it would be angled toward the floorboards so much it would be unusable. So I rebent them and got it installed. So, as a professiinal mechanic, with the correct tools and equiptment, it took me an hour or ao of modification to make it fit. If you're going to try this at home... Be ready for heartache and frustration. After contacting Jegs, there answer was to take pictures. Well... Who is paying me to take it back off so I can so only some of the modifications. Right now it looks like an installed y pipe. Dissappointed with the purchase, the part, and mostly Jegs.

    Which headers will mount up with this y pipe? My truck is a 1997 Chevy Silverado z71 5.7l 350 

    Asked by: Chevy z71
    This will mount to the stock exhaust manifold and should hook up to these headers - https://www.jegs.com/i/JBA/578/1832S/10002/-1

    I recently order this pipe for my 1996 Chevy Silverado 2500HD 5.7 RWD - will this pipe in combination with 2.5” Dynomax H pipe work on this truck?

    Asked by: Jeff13
    You will need to modify these pipe kits to get them to work together properly.

    Will this pipe work for a 7.4 liter or do you have another part that will?

    Asked by: Moonmark1980
    No it will not and at this time we do not have a part number in the Jegs brand.
