I put a set of the old crimp style Magnaflow 14x7x3.0 inch side inlet and center outlet muffs at the rear bumper with 3.0 inch pipes all the way through the system from the Hooker fenderwell headers on my old pump gas Duster, that car picked up .02 ET and .2 MPH in the 1/8 mile only with them off. shock No since in removing them really work
They where okay as far as in car hearing at part throttle, WOT got a lot louder shruggy
On another bracket car a set of 3.5 inch Bullets off of the A body fenderwell Hooker headers slow that car down .1 ET and 1.2 MPH in the 1/4 mile shruggy
