Turbocharged vehicles aren't a common sight. You'd normally only see them in video games, on TV, or in movies. If you've got one sitting on your garage, then consider yourself very fortunate; you've got a high-performing ride after all. While a turbocharged automobile is already great as is, there are plenty of ways to make it even greater. You can add all sorts of accessories and replace various stock parts. One surefire way to get more horsepower for your car is to replace your stock catalytic converter with a downpipe.
What does a downpipe do, exactly?
Simply put, a downpipe directs the exhaust from the turbo charger to the exhaust pipe. A downpipe provides better exhaust capabilities, allowing for an improved performance in your car. In fact, you can get as much as 15-20 more horsepower with a downpipe equipped to your car.
If you're wondering what may be the possible downsides of using a downpipe, the answer to your question is none. There haven't been any reports of downpipes causing other areas of performance to suffer, unlike other performance modifications. That's the very reason why a downpipe is one of the best ways to upgrade your car.
What downpipe should you buy?
There are several kinds of downpipes in the market. You'll find plenty of brands that offer them. However, there's really not much difference among all of them in terms of function. They basically perform equally. With those said, we advise you to get a downpipe that's made of stainless steel. There are also mild steel variants, but they naturally won't last as long as the stainless steel versions.
Getting a stainless steel downpipe is our only recommendation. The style/construction of the downpipe that you're going to purchase is up to you. Stick with your preferred style as long as it fits your car. Again, there aren't notable differences among them. Below are the descriptions of the various downpipe styles.
- Blank plate ? This is the most similar to stock downpipes. The wastegate portion of the pipe is covered. Generally, this is also the cheapest of type of downpipe.
- Twin dump/Divorced ? This looks like the blank plate-style downpipe except for the fact that it has a hole for the wastegate portion.
- Bellmouth ? It's a downpipe that's completely open.
- Split Bellmouth ? It's a bellmouth-style downpipe with a divider in the middle.
