Can this be used in the front or rear?chris p.Oct 17, 2020
Best Answer:Hi Chris, This is for the front, driver side applicable to several Chevrolet models. To check the fitment please use our Vehicle Selector — which can be found towards the top of the homepage as well as all categories, search results, and product pages — can help verify if a part will fit your specific application. To enter your application, simply select your vehicle’s year, make, model, sub-model, and engine type and click “Go.” Once your application is selected, you’ll see a “Guaranteed to Fit” badge if the part will fit, and we recommend that you also double-check Your Vehicle Fit Details as well as the Vehicle Fitment Information table on the product page.

I have a 2017 chevy silverado 2500 hd, 6.0l with 3 catalytic, can i replace them ?Paul L.Sep 29, 2020
Best Answer:Hi Paul, Yes, they are replaceable. We suggest a direct bolt-on y-pipe assembly instead of the universal catalytic converters. We currently don't carry them for the 2017 Chevrolet Silverado 2500 HD 6.0l models, but you can check the dealership directly to get the perfect fit.
