Sorry don't know a lot about exhaust, but interested in getting a Super44 Flowmaster muffler only installed on truck. But every site says not available for truck. I have side only exhaust if that matters. Any help appreciated, I figured they were universal fit.

 

I just had a Flowmaster Super 44 installed on my 2020 Silverado Trail Boss. It has a nice, deep tone to it.

 

Any performance or Mpg gains ?

 

Have you noticed any affect on the AFM(active fuel management system) when this kicks into 4 cylinders?
