How difficult is this to install? Does it require the use of a welder? Does it connect right on the stock cats? Is there any modifying needed to fit this to my truck?

  • The Flowmaster Force II Aluminized Steel Cat-Back Exhaust should be a simple bolt on installation. It does not require any welding, modification and should bolt up to right behind your stock catalytic converter. Note: Does not fit the 1997 model year, SVT Lighting and 2002-2003 Harley Davidson Edition trucks.

    Sounds great! Very timid with deep rumble when at idle and daily driving but really screams when you stomp the pedal. Especially when paired with shorty headers and if you you really want to open up the exhaust then cut the cats!
