It has increases horsepower and throttle response. I hollowed out my catalytic converters first though. The flowmaster has a great sound to it.

Sounds absolutely amazing on the 5.0 coyote! It definitely is much louder inside the cab but I knew that going in. Cruising at highway speeds is very manageable. Cold start-up is very loud and cackles nicely. The rest of my exhaust is stock.

THE MUFFLER HAS A SLIGHT RUMBLE, WHICH IS WHAT I WANTED. I PLACED MY ORDER BY PHONE TO MAKE SURE I GOT THE RIGHT ONE. I ORDERED THE ONE WHICH WAS OFFSET. I TOOK IT TO THE LOCAL MUFFLER SHOP TO HAVE IT INSTALLED. THEY SAID IT DIDN'T LINE UP AND HAD TO MAKE A CUSTOM "S" PIPE TO MAKE IT WORK, COST ME AN EXTRA $50.
