    31004 - JEGS Off-Road Y-Pipes for Trucks is rated 3.8 out of 5 by 12.
    Rated 5 out of 5 by from Great Product Fits many LS equipped trucks/swaps. I bought this for my 91 Silverado 2wd with a 5.3 swap and it fits perfectly. I have also used this on a 99 OBS 4x4 with a 6.0 swap. Also used it on a 2005 Sierra 4x4 with a 5.3. This Y-Pipe fits very good, never had any troubles. Only gripe is the price fluctuates a lot. First time I paid $220 then it went down to $125 now its up to $170.

    Rated 5 out of 5 by from Great Quality Bought this for a 95 Chevy K1500 with a 5.3 swap running stock manifolds. Lined up perfectly on it, flanges were good, o2 bungs were good, welds were good.

    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.

    Rated 4 out of 5 by from 2000 Yukon XL This pipe was not listed for my model, but i was able to make it work for “ off road uses “. The problem was that the right secondary sensor bung is right at the frame. I was able to use one of the plugs that came with the pipe to close the hole. Next i relocated the sensor to a new location on the pipe. ( had to hook it up to prevent the CEL from coming on). Also used a 2” butt splice where the two tubes meet in the middle. It makes a much nicer connection that doesn’t deform the pipe like a U-clamp.

    Rated 4 out of 5 by from Fit my 04 suburban 5.3 Fits 2004 suburban 5.3. Doesn't list it but it fits. With a little patience the install went well. Took about 2 hours.

    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.
