Description
Fabspeed’s Maxflo Performance Exhaust with Quad Tips replaces the heavy, restrictive Mercedes-Benz mufflers to shed weight and deliver a deeper, more authoritative AMG V8 tone. On Fabspeed’s DynoJet it recorded maximum gains of +22hp and +31ft-lbs, with peak increases of +19hp and +21ft-lbs.
