    Posted by Jesse Chitty on Feb 1st 2026

    I've had these on my 01' 2500HD for over 10 years and 2 different engines and they are phenomenal, the highest quality, they flow very well, probably one of the best features is they don't leak, anywhere, not at the flange ir reducer. The price seems steep, but after 10 years they still look great. I won't but anything else.
