I ran the early crimped steel Magnaflow 14x3 center outlet and offset inlets on my Duster mounted behind the rear end between the sub frames and 1/4 panels. They sounded decent in the car at part throttle cruise and weren't horrily loud at WOT, most peole said they really like the sounds of them when driving it on the street or at the track At the local 1/8 mile track removing the complete exhaust system pick the car .03 ET and .2 MPH, not worth doing IMO Has anyone on here ran the longer stainless steel Magnaflows 18 or 24 inch long straight (not the three chamber ones) through muffs yet?If so how did you like them. I'm putting a 1966 Dodge Coronet Deluxe together with a 440 motor and Hooker headers with Summits 3 inch pipe kit without muffs, any comments on those muffs appreciated
