335d exhaust

Types of 335d exhaust

There are several 335d exhaust options, each with its features. They include:

• Cat-back exhaust system

  This system starts after the catalytic converter and includes the muffler and exhaust pipes. It is a popular choice for many BMW 335d owners because it improves exhaust flow, resulting in better engine performance. The system also gives the BMW 335d a more aggressive sound and enhances its overall look.

• Downpipe

  A downpipe is a component that replaces or upgrades the existing pipe connecting the engine's exhaust manifold to the rest of the exhaust system. The downpipe aids in lowering turbocharger spool times, resulting in a more responsive performance. It also contributes to a more aggressive exhaust note and aids in lowering overall exhaust system temperatures.

• Muffler

  The BMW 335d exhaust muffler can be modified or replaced to achieve the desired sound and performance characteristics. A performance muffler typically contains fewer internal baffles or no baffles at all, resulting in a more free-flowing design. This configuration generates a louder and more aggressive sound compared to stock mufflers. The mufflers are made from materials such as stainless steel, which is corrosion resistant and durable. They also have perforated internal tubes that allow sound waves to move freely, thus creating a raspier sound.

• Axle-back exhaust system

  An axle-back exhaust system is installed at the rear of the vehicle, just in front of the rear axle. It typically consists of new exhaust pipes and a muffler. The axle-back system improves exhaust flow, enhancing engine performance and producing a more aggressive sound.

• Quad-tip exhaust

  This is a BMW 335d exhaust tip that comes in a variety of designs and finishes, such as chrome, polished stainless steel, and black-coated options. The quad-tip configuration gives the vehicle a more aggressive and sporty look, enhancing its overall aesthetics.

Specification and maintenance of 335d exhaust

All models of 335d exhaust systems have similar specifications, which are as follows:

• The main material used in the production of 335d exhaust is stainless steel 304, which is known for its anti-corrosion and anti-rust properties.
• The wall thickness of the 335d exhaust pipe is 1.5 mm, which makes the exhaust pipe more durable.
• The diameter of the 335d exhaust pipe is 76 mm.
• One end of the 335d exhaust pipe is flat, and the end is curved. The flat end will be welded to the muffler, while the curved end will be the tip of the exhaust pipe.
• There are two big logos on the 335d exhaust pipe, which is used for advertising purposes.
• In order to ensure the smoothness of exhaust gas in and out, the inner wall of the exhaust pipe is polished to a smooth surface.

In terms of maintenance, buyers can refer to the following instructions to maintain the 335d exhaust system. First, regular maintenance is very important. Remember to check the exhaust system for damage, corrosion, and wear and tear after every 5,000 miles or every 6 months. Also, visual inspection before long trips is necessary. This allows one to identify minor problems before they become major issues. It is also advisable to check the hangers, brackets, and support pipes for damage. These components are easy to be overlooked but are very important for the 335d exhaust system. If they are damaged, the whole exhaust system will be affected. Secondly, cleaning the 335d exhaust system is very important. Remember to clean the exhaust system regularly using a soft brush and mild detergent to remove dirt and debris. Also, using a rust inhibitor can help prevent corrosion, increasing the lifespan of the exhaust system. Thirdly, it is advisable to use high-quality replacement parts when repairing the exhaust system. This ensures that the warranty of the vehicle is not voided and guarantees that the spare parts will fit perfectly.

Choosing the right 335d exhaust

Choosing the right 335d exhaust can be a daunting task, but it doesn't have to be. Here are some factors to consider when buying a 335d exhaust:

• Purpose: It's important to consider the purpose of the exhaust system. Do you want improved performance, a more aggressive sound, or both? Different options cater to various preferences.
• Material: Exhaust systems are typically made from stainless steel, which offers durability and resistance to corrosion. Consider the material's advantages and how they affect the overall performance of the vehicle.
• Fitment: Ensure that the exhaust system is designed for the specific 335d model year. A proper fitment guarantees optimal performance and avoids potential issues during installation.
• Sound level: Consider the desired sound level and exhaust note. Research different options and listen to sound clips to get an idea of the sound characteristics. Some exhausts offer a deeper, more aggressive tone, while others may be more refined.
• Legal compliance: Check local regulations regarding exhaust emissions and sound levels. Ensure that the chosen exhaust system complies with legal requirements to avoid penalties and ensure road legality.
• Brand reputation: Research reputable brands known for producing quality exhaust systems. Look for reviews and feedback from other 335d owners to gauge their satisfaction with the product and customer service.
• Budget: Set a budget for the exhaust system and consider additional costs such as installation, tuning, and any necessary accessories. Compare prices and features within the budget to find the best value for money.

How to DIY and Replace 335d exhaust

Many BMW 335d owners contemplating exhaust replacement may want to try it out as a DIY project. It is achievable with the right tools, parts, and car maintenance knowledge. First, check if the warranty is still valid to avoid voiding it in case of a botched DIY. If not, follow the steps below or consult a professional.

To replace a BMW 335d exhaust, get the following tools. A socket set, ratchet, combination wrenches, 12-inch extensions, 3/8-inch drive swivel socket, and a lift or jack and jack stands will be needed. The parts needed are exhaust system components, including gaskets and hangers. Follow the steps below:

• 1. Raise the vehicle and secure it on jack stands.
• 2. Remove the section of the exhaust that the manufacturer instructions indicate.
• 3. Install the new exhaust system by following the instructions provided by the manufacturer.
• 4. Start the engine and check for leaks.

It is essential to ensure that all components are tightened to the specified torque and that there are no leaks or rattles in the new exhaust system before hitting the road.
