Because it's tucked out of sight, plenty of people forget that the down pipe even exists on their truck. You can do better with our 2007 to 2013 Sierra down pipes by upgrading yours, so you not only remember it's there, but also boost performance with a high quality version. This is almost an essential step if you are modifying your GMC's exhaust, because of the restrictive nature of the stock down pipe. The versions we have allow for quicker exhaust flow, thanks to larger diameters, and interior walls that are slippery, so the air moves without obstacles. That translates into more horsepower and torque from the engine, plus an improved throttle response. It's a nice addition to aftermarket exhaust headers, a cat-back system, or whatever else you want to install. Before you select a down pipe, you should decide if you're going with long tube headers or shorty headers, if you have not already selected one option, because that will affect which kind of down pipe you can use. You also need to match up the diameter of your headers with the downpipe, ensuring proper fitment. No matter which of the down pipes on the site you end up buying, top notch quality is standard across the board. We have teamed up with some of the best aftermarket brands to ensure you get a quality setup. All down pipes are made of solid, durable materials such as stainless steel, and feature solid manufacturing techniques, ensuring better longevity than inferior products.
