Calling All Motordyne ART owners

Silly Rabbit

I added ART pipes to my Borla cat back and it's on the edge of too loud. The Borla is a true dual with no resonators. It has a deep tone to it. Adding the ART pipes is giving me an unwanted drone for around 2k rpm. At idle and WOT, it sounds great. At highway speeds it easily tolerable, but around town driving can be annoying at points. I am planning to pick up some fast intention rhfc for comparison. I liked the Borla with stock cats, but wanted to free up the exhaust, keep the deep tone and raise the volume. The ART pipes did that, but maybe too much. I don't have any rattle issues, but there is a slight rasp at times.
