The stock parts in your exhaust system are a lot like sitting in bumper-to-bumper traffic. It releases a little at a time and gets you where you're going… eventually. But, with Buick Rainier exhaust, mufflers & tips from AutoAnything, you move from gridlock to a lane unobstructed as far as the eye can see. Because, unlike stock components that simply provide a conduit for spent gases to escape, performance exhaust systems are engineered to maximize your engine's exhaust flow, allowing the gases to escape faster and your engine to breathe easier as a result – amping up both your horsepower and torque.
