I have a 40 series on my truck that works fine. I am interested to know how all you people with the dual 40 series mufflers are mounting them. Where is the room to do it? And what pipe setup are you using? And finally, sound aside, would the flow with the custom setup be better or worse than that of a actual catback designed for the car? thanx

 

do a search for dual exhaust
most people mount them with dumps behind the rear axle. it would depend on the size of the pipe but dual 2.5" outflows single 3"
