What Does a Downpipe Do?
The downpipe directs exhaust gases away from the turbocharger and into the exhaust system. By upgrading to the TBH Performance Co. Downpipe, you eliminate the restrictions of the stock downpipe, allowing exhaust gases to exit more freely. This reduces turbo lag, increases boost potential, and ultimately boosts power by ensuring more efficient gas expulsion.
