Replaced the OEM primary cats with the Flowmasters and got a high quality product for a very reasonable cost. Very happy with the end result.

Not quite as powerful as straights, but way ahead of the other flowmaster models. I have the 3" in and dual 2.5" out and the sound is awesome. I have 12" turndowns right where the bed meets the cab so that causes plenty of cabin drone. Overall great sound from outside. Going from stock to this even added enough hp that i can spin my 35x12.50s on dry pavement. Something i couldnt do before!
