Tenneco Automotive has announced the launch of a consumer rebate program on its line of Quiet Flow mufflers. The Walker Quiet-Flow ‘Cash-In2’ program is in effect from now through May 15, 2002. Consumers who purchase a Quiet-Flow muffler from a participating service provider will qualify for a $20 rebate cheque from Tenneco Automotive. Quiet Flow mufflers feature 70 miles of advanced sound-absorbing fiber and an exclusive free-flowing design. The patented Quiet-Flow design delivers an average of 24 percent greater exhaust flow than competing mufflers, minimizing power-robbing system backpressure, says the company. Each Quiet-Flow muffler features a number of unique design and construction features that ensure exceptional performance and durability, including all-aluminized steel construction, spun-locked heads, bridged necks and double-wrapped body.
