    Great video. Can you take apart the stock Muffler to show us what's inside it may be cut it in half?

            The proper way to check drone on a 2500-3500 truck is on the highway, going up a hill at 70 MPH pulling a big load.

                I'm guessing for that money it's not stainless steel and not mandrel bent? thats super cheap. I think you need to remove more of those extra mufflers, lol. one thing that made my truck much louder where high-flow cats. remove the floor Factory ones put to high-flow ones in, it was much louder even with the stock Muffler.

                just truck needs dual exhaust, angled tips coming out the rear side, and some long tubes 👍

                    I think if you check out decibels of sound the number on the meter is more than you think in energy. Check with an expert.

                                              Oh no, you LOST power with a chambered flowbasterd, should have used a straight through muffler design like a Magnaflow to gain sound and power, true dual is just dreaming at this point.

                                                        Your interior reading incresed by 3db, which translates to double the Sound Pressure Level (SPL) at the median measured frequency--or twice the exhaust noise.. not as inconsequential as you may think. ..Still sounds better than an Ford EB Engine. Regardless, fun video to watch thanks guys!

                                                          I think it sounds good. like to know how it performs pulling a trailer and what the sound level is in the cab with something like a box trailer.

Stock ! 1 pipe from each exhaust manifold into separate cat convertors then into 1 exhaust pipe. Stock ! Seems to me a true dual exhaust system could be built and retain the cat convertors

                                                                    • Nashville Lewis-Jones

When I was looking at exhaust systems for my '13 Raptor I wasn't happy with what I heard or $$$. Love the $$$($100) muffler and no mods to fit. Hardest part was removing the big old exhaust, definitely removed the spare tire which helped alot...especially since it was not on a lift. The looks and compliments I receive are plentiful and when I tell them I spent $100, shipped directly from Flowmaster in less than a week...jaws drop 😏
