Long Tube Headers for Durango 5.7L
Verified Buyer — Sean Dalton | November 7, 2025
I got these headers around march 2025 and I can personally say I've enjoyed every second of them. What they do for the cars exhaust system unmatched and makes it unlike anything I've ever driven. I have to give this products a five out five for not only the build quality, but also the performance it gave the car. I don't think I'd be able to live without long tube headers on any car ever again. The only thing I might be mindful of is the O2 sensor behind the driver side catalytic converter. I had an issue with the heat shield, which caused my O2 sensor of melt. It wasn't that big of a deal because I was able to replace it, however be mindful of this when installing it on your Durango. Overall, I'm exceptionally happy with this product and I would buy it again.
