just had a 40 series Flowmaster installed and now my fuel mileage sucks I can't seem to keep my foot out of it

 

40 series original? What is your setup exactly? i have a 2.5" dual in/out super 40 series in my living room waiting on my truck to get out of the shop...

 

i dont think that he meant because of the Flowmaster the MPG went down, i think he means that because of the sound of the Flowmaster the MPG went down, i have that problem too, theres just something about a lead right foot that runs through my family....its a blessing and a curse i tell you.


you enjoyin your new exhaust then i take it?

 

Yea I just like the sound of it
