The exhaust on your car or truck is much more important than just the sound it makes. Many people today are more worried about sound than flow. We need to realize that the exhaust of your engine is the gasses leaving the engine, and we want that to happen quickly and as efficiently as possible. Efficiency is even more critical on turbocharged engines because the exhaust gasses are extremely hot.
Because of HSP Diesel's in-depth knowledge of the subject, we have brought a few different brands onto our site to allow you some additional options. Those brands include BD Diesel and PPE, with items like downpipes, exhaust manifolds, and even exhaust brakes. A performance exhaust can sound great, but its main focus is free-flowing and well-fitting.
HSP Diesel has worked extremely hard on our Billet manifolds that are unlike any on the market today. When paired with other high-flowing items inside the HSP line, you will be pleasantly surprised with your truck's change and overall results. What you will learn is that you don't need to have a custom exhaust to have a good flow; you need to have the right parts and the right people in your corner, like HSP Diesel or BD Diesel.
