Gibson Exhaust Claims - Diesel Forum

Has anyone else seen the claim by Gibson that they have a cat back system (which I assume includes the DPF) that lowers the exh temp by 400F?

My 03 runs at 1000-1100F towing. It runs at 600F loafing down a flat interstate at 65mph. If Gibson could prove with a test report that they can lower towing temps to 600F they should get over here and do so. The physics just don't make sense.

diesel power mag did a test on that system this month. little difference n sound, decent difference in temps not 400 though

There isn't anything after the cat/dpf filter to improve on.
Total BS in my opinion, and I don't need to see any tests.

Thanks for stopping, I enjoyed the visit!
