I have something to discuss exhaust system for Cummins 5.9. Usually, I purchase the truck spare parts from BC Diesel online store. This time also I checked their website for this. There I found products from two different companies. Here is the site link https://www.bcdiesel.ca/en/exhaust-s...mponents-1-1-1 . I need the help of experts to choose the best company among this two. Could you please check this and tell me which brand would be better?
