40 series Flowmaster w/ 3" piping installed Sunday. Sounds awesome! The truck really rumbles now and it seems as if throttle response has improved also. With the windows up and the radio on (not loud) you can`t even hear it, i`m very pleased =)

Sounds like an awesome setup! If I could do it all over again, I would probably go with your exact setup instead of the Force II catback.

Just a few questions: Is your 40 Series muffler a Delta-Flow or the regular? and is it a 3"-in/3"-out?? can you post some pics??

Thanks!!

Hey BlownF150,
Did you notice any loss in low end torque with the new 3inch pipes? I'm in the market for a flowmaster exhaust myself, but I don't want the truck to be a dog off the line.
Any info much appreciated.
