I recv'd the progressive exhaust after a short backorder delay. Thanks to Carven's Youtube channel, installation went pretty smooth. I took around 3 hours but that was mainly because I jacked up the truck a few different times. a couple times lifting the rear chunk to get work clearance and the frame a couple times to get the old exhaust to clear the rear end. Sound is just what I was looking for except, honestly its louder on cold start than I thought but I can absolutely deal with it. At low to mid rpm is about comparable to the a/c blowing in mid to high range. WOT is definitely going to get peoples attention. Thanks Ryan and whole team at Carven. I highly recommend the progressive for anyone wanting a big improvement over stock. Oh yeah, if doing the install yourself, save the headache and get a hanger removal tool.
