I recently had the magnaflow 16870 cat back duel exhaust installed on my truck and I love it. I rated the installation avg only because i didn't install it but it took the guy at the muffler shop just 1 hr. to install it. cruising at highway speed you can barely hear it . when you step on it its got a nice rumble to it. cab noise is minimal and is just during take off from a light or stepping on the gas to accelerate faster. with the radio turned up its even less. overall I'm extremely happy
2011 RAM Big Horn Crew Cab 5.7L Borla Touring Exhaust Systerm
Everything arrived fast and complete. Took my mechanic and I about an hour or so, to take off the existing exhaust system and put on the Borla Touring Exhaust System. Looks great, especially those five inch stainless steel tips, and sounds just what I wanted as advertised, a little more than stock, but, certainly noticeable that it's not stock. I only drove the RAM on a country road, easy driving about 60 MPH for 40 miles and got 21.7 MPH, time will tell when I pull my 29' trailer. Thanks!
