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 budget system includes a Helmholtz resonator (to kill that annoying drone associated with aftermarket exhaust). Our budget system is $379 in aluminized steel and $479 in stainless steel. The sound is very aggressive with a slight raspy sound at certain rpm, but it is a very narrow part of the rpm range that you hear the raspiness. Otherwise the sound is a combination of mid and high until you reach 65mph (this speed and sound comparison is based on stock 32″ tires, stock 4.30 tow gear option, and transmission in 6th speed with the torque converter fully locked up. Your truck will see these conditions 99.9% of the time when on a highway at that speed). All systems are built to order, please allow up to 30 days for a complete build.
