The ISR Performance 4.5″ Exhaust Silencer for the ISR GT Series Exhaust has been designed to be used on the GT Series exhaust system with 4.5″ tip. It DOES NOT FIT Series II Titanium GT Exhausts.
The exhaust needs to be drilled to accommodate the Silencer set screw hole. Set Screw is not included. Easy install and removal!
Please verify compatibility before purchase. May require some modification for proper installation.
