change your sig
btw how did you get 2 spintech mufflers on there? did you go with true duals? or did you have it split and have one muffler on each side of the split.
yeah its loud it shook the window at the muffler shop when he started it and the guys at the muffler shop were making some weird faces when they saw the mufflers but that changed after the install
Which SPintech models? My friend has a Spintech Sportsman or SportsmanXL SI/DO on his 01 Dakota 4.7 and it sounds pretty darn sweet. Similar to a Flowmaster 40, but without the drone inside the cab.
