All You Need to Know About BMW Downpipes

A BMW downpipe directs exhaust gases from your vehicle's turbine housing to your exhaust system. The downpipe bolts directly to the turbine housing. It helps to move exhaust gases through the system as efficiently as possible. The average downpipe has at least one restrictive catalytic converter. These do a great job of cleaning up exhaust fumes as they are produced. The only problem is their restrictive aspect. They make you lose power.

 

 

A downpipe is fitted as it allows the turbo aspect of the engine to be more efficient. The downpipe directs the gases away from the turbine, creating more uninterrupted power. When you step out right away and open your Mercedes or similar vehicle, you will feel the difference. Secondary market downpipes generally have wider capacities and are less restrictive than the stock option. This increase in diameter allows for more space for faster turbo spin.

THE DIFFERENCE BETWEEN CAT VS. CATLESS

If you want to get an aftermarket BMW m5 downpipes, you are going to come across two types: cat and non-cat. Catted means it comes with a high-flow catalytic converter. Catless downpipes come without.

Catalytic converters clean exhaust gases as they pass through a catalyst. This deals with the smell of raw exhaust fumes. If you get a catless version, the vehicle will emit a noticeable odour. This is because the exhaust gases are not cleaned before the vehicle emits them.

You probably don't want the smell that comes with a catless converter, which is why many sports car owners opt for the catless variety.

BUYING A NEW DOWNPIPE

If you aspire to race your sports car, this is one of the most common reasons for replacing the downpipe. You may choose to do this simply because you are trying to get as much power out of your vehicle as possible. Adding a new downpipe to older model sports cars can dramatically improve your HP.

There is another potential reason. You may have modified your turbo to run at a higher boost pressure. If you increased the amount of boost from a stock turbo system, the increased exhaust output may require smoother, larger m5 downpipes.

Keep in mind that the standard downpipe for sports cars is generally of excellent quality. It's entirely your prerogative whether you're happy with your exhaust materials or want to tweak them further to get that extra boost.

To be safe from any kind of bottom situation. you need to pay attention to the fact that the "Check Engine" indicator may light up. Since this is a new part and your car is designed to work primarily with factory drainpipes. Your car's "Check Engine" light may come on because it thinks your exhaust system is suddenly quite inefficient. This can be fixed with some tweaks and minor changes.
