That sounds a lot like my Magnaflow system. I wanted the dual side out but was afraid it would drone in the cab too bad. I love the way that it looks.
Thanks!! thats was the most entertaining trip to Walmart i have ever made the cabin drone is minimal and with the radio on you cant even hear it except of course when you accelerate.
When they cut the pipes and bend them they put some kind of oil/lubricant on it so it burns off in the beginning and the smell is terrible.
