Urethane Exhaust Hangers

List Price $14.45
Our Price $10.80

The Cobb Tuning urethane mounts are much more rigid than the soft, factory rubber mounts and come in handy when your exhaust system occasionally taps the differential or sway bar during aggressive driving. On the WRX, there are a total of 4 hangers of this style which are used -- three on the muffler section and one on the intermediate pipe. Each sold separately.

Turbo Heatshield STI

List Price $67.56
Our Price $50.48

Stainless Steel replacement is an ideal replacement particularly when installing aftermarket downpipes. Running without a turbo heat shield can increase underhood temperatures and unnecessarily heat your intercooler. We highly recommend you either trim your factory shield (free) or purchase our shield rather than running with no heat shield at all.
04-07 STI stock turbo only.
