I added a flowmaster super 10 into the factory U pipe and reduced raspiness and metallic sound that this exhaust makes. It was an idea I had when I was already at the muffler shop and my resonator wouldn't fit in the y. Hopefully it won't be restrictive enough to rob hp at the wheels. Anyone else use a race muffler instead of resonator to fix rasp. I have high flow cats by the way also.
