2011-2014 Sierra GMC 2500 HD 6.6L Duramax 3" Turbo Exhaust Downpipe Black

Excellent resolution for the Check engine Light.

Installation was a breeze, thanks to the kit's comprehensive design and clear instructions.

The new ignition module was installed without major issues, though the spark plug wires were uniform in length, unlike the original OEM part which had one longer wire to reach the farther spark plug. With this replacement, the wire barely made it to the distant spark plug, while the coil for the closer one had to be looped over the engine. Another challenge was connecting the reverse plug and another connector the module's male terminals were round, while the snowmobile's connectors had square holes. This made the connection difficult, requiring some wiggling to fit the round pins into the rectangular slots. Despite these minor fitment issues, the snowmobile started on the first pull and is running smoothly with the new module. Hopefully, it will prove durable over time.

These Magneto Stator Rectifier Gasket Set totally exceeded my expectation. They provides a reliable power upgrade to my bike's electrical system. The only problem is it takes too long to get it. But anyway, it works great.

Fit well

This product works well. When I installed this eliminator, the B2 catalytic converter for my 2016 3.7L Ford PIU was priced at $1,400. I had previously installed the same part on my 1998 4.0L Jeep Wrangler, and it has been performing great. Only time will tell if it holds up long-term, but I hope I can find replacement cartridges if needed. The delivery was delayed by two days due to the UPS-to-USPS handoff.

Definitely would buy again if ever needed. Plug and play, no programming needed.

They shake a little less than the stock, the look better and less bug antenna like. Definitely feel like I would buy these again. My picture shows the stock mirror on the right VS the new install on the left.

Great handles easy install

I'm so glad I ordered this replacement screen! The dealership quoted me $600 to 'fix' it, claiming the radio needed replacement, Even though everything worked fine except the display. I knew that wasn’t the issue, and this affordable solution proved it. Works perfectly now!

Perfect replacement for my Harley road king and saved a couple hundred dollars, just hope it last

he performance of all 8 coils has worked well so far without no misfire. So, I would recommend them to others to try out also.

Get right of that P0420 CEL code

I tested the product when it arrived, but noticed one side was loose. I managed to stop and remove the wing, though I lost the E-clip and spring. The seller was responsive and sent replacement parts a new pin, E-clips, and spring. I’m happy to report that I just completed a 12-day, 2,700-mile trip, and they performed flawlessly. On hot days, they helped direct airflow toward me, and they deflect wind as well as (if not better than) the original stock parts, likely because they’re taller.

There is nothing in terms of customer support so you're on your own in terms of figuring it out. The throttle linkage and the case breather for example are a custom fit. The upper throttle link has a threaded fit, probably for Kawasaki (not sure) that is clearly specific to one very specific linkage set. The lower link is an open c and much easier to work with.

I wound up making a custom bung to make the upper linkage work. It was annoying, but overall not bad.

Beats spending $400+ on a stock carb for a 25 year old bike.
