1.Budget Dumped System. This system is our most simple Tundra exhaust system. It literally replaces the stock muffler with straight pipes that tie into a Y pipe. The standard budget dumped system includes a Helmholtz Resonator which will reduce the drone; however it is still significant and will be heard at freeway speeds. IF DRONE IS A CONCERN – THIS SYSTEM IS NOT FOR YOU. The sound is very aggressive with a slight raspy sound at certain rpm’s, but it is a very narrow part of the rpm range that you hear the raspiness. All systems are built to order, please allow up to 30 days for a complete build.
