Anybody tried a doug thorley turbo back?

[BBowers]

I am looking to put on a turbo back system on my 03 soon. I want a muscular sound but little to no drone, so I am looking at 4" systems. I saw good prices on the DOug THorley kit, aluminized for under 300 bucks. how does it fit?sound? DOes MBRP drone on the hwy empty? BULLYDOG? WIll I gain mileage?

My MBRP starts to drone m/t on the interstate around 2000 rpm, not too bad, but the higher the rpm the more pronounced.



It is nothing like my 340 Duster was with the Purple Hornies, but there is drone, mine is a 5" system, not sure if the 4" is better or worse.
