Can we replace the factory cats with high flow cats or is there a place that sells test pipes? Can't wait to hear it!!!!!

 

How bout going cat less!

 

They used my truck for the mock up I also did their cat back kit which I know is pricey but to me well worth the cash I also did a custom tune that woke the truck rite up we just recently went on a long road trip and it actually got 22mpg cruising at almost 80mph the whole way ARH is def the way to go!
