Additional Information

The CarBahn High flow exhaust is made of stainless steel for maximum durability. This is a complete cat back exhaust not just a pair of axle back mufflers.

The CarBahn exhaust retains the OEM catalyst and electronic controller valve in the mufflers for a mellow sporty sound when driving normally without the drone usually associated with most aftermarket exhausts. When you go to WOT ECU will open the electronic valve increases flow for maximum power making a very sporty sound without being too loud.

The exhaust comes with stainless tips however a CarBahn, Carbon exhaust tip is also available.
