    No luxury sedan appeals to both the young and older driver with as much ease as the Buick Lacrosse. Whether you drive a first-generation model or a 2012 model, a little more horsepower will make your Lacrosse more exciting to drive. The most effective, simple and affordable way to get more power out of your engine is with a custom exhaust system. CARiD sells a range of state-of-the-art exhausts for all 2005-2013 Lacrosse models. Built using the latest technology, Lacrosse custom exhausts from CARiD will give you an additional 10-15hp as well as more torque. This means greater pull, faster acceleration and greater throttle response. Borla, Flowmaster, MagnaFlow and Onki cat back exhaust systems will give you increased power, torque and more engine efficiency. In addition to enhanced performance, chrome-finished exhausts such as the Onki range of exhausts for the Lacrosse will give your car a more polished look.

    A custom exhaust replaces the quiet tone of the stock exhaust with a richer engine note, whilst preserving the quiet sound-proofing in the cabin. If you’ve always wished your Lacrosse sounded as powerful as it looks luxurious, you have the opportunity to make that wish come true with a custom exhaust. That’s not all you get though; a custom exhaust system from CARiD will take care of your exhaust system problems once and for all. You will not need to keep replacing the exhaust, as it does not wear out easily, not even under heavy use. If you are an enthusiastic driver, this just means you can drive on all kinds of roads and weather without worrying about your exhaust coming loose, leaking, having a blockage or rusting. From whichever angle you look at it, a Lacrosse custom exhaust is a great deal.
