911 GT3 Street Muffler

Dual Inlet Dual Outlet 911GT3 Street muffler is designed for use on Porsche 911 1965-1989 models.  Tailpipes spacing is  centered under the license plate with 2.5″x8″ tailpipes as standard.  Installation on early models may require a slight relief in the bumper valance.  Installation on impact bumper models requires cut-outs in the valance.  We have custom fiberglass valances for this purpose.  Please see ACCESSORIES for optional tailpipe treatments and valances.
