3 weeks back I bought a 2007 Dodge Cummins 6.7. In the regular service, the mechanic told me to replace the exhaust system as it is not in a perfect condition. When I searched for exhaust systems, I found some options here https://www.bcdiesel.ca/en/exhaust-systems-ford-03-07. There are products from two companies (MBRP and Flo-Pro). Which company product would be better?
