How to Choose the Best E46 M3 Exhaust?

By selecting the appropriate E46 M3 exhaust system, you can enjoy long-lasting and durable items. But before going to purchase these items, you need to remember some points.

  • Exhaust Construction

The construction of exhaust can be mandrel bends or crush bends type. Piping bends are the critical difference between aftermarket and stock exhaust systems. The stock exhaust tube is customarily formed using a crush bending technique. Though crush bending is a fast and straightforward process, it also contributes to the limitation of rolling pipe bends’ efficiency.

The aftermarket exhaust firms use a method known as mandrel bending to remove these constraints. This procedure uses a lightweight rod inserted in the drainage channel. This flexible rod stops the tube walls from cracking or twisting when the rod is twisted. The effect is a cohesive tube diameter without limiting curves.

  • Check Exhaust Materials

The expert technicians manufacture these exhaust systems from various materials in applications like stainless steel or mild steel. The most significant value of a mild steel exhaust is its expense. Although these systems are going to save you money, they are going to corrode or rust. 

Stainless steel prevents rust and is suitable for snowy or wet climates. 

  • Check the Exhaust Configuration

The design of an exhaust system is another significant factor in choosing it. Dual crossover, dual, and single configurations are standard. 

The most popular configuration is the single exhaust system. This configuration has a single collection of exhaust elements, including an exhaust muffler that naturally flows behind the car’s axle. 

With wide tube diameter and less restricting mandrel bends, the aftermarket exhaust systems can supply a substantial improvement in efficiency over inventory. Furthermore, they are typically cheaper and lighter than real dual-rear exhaust.

Dual exhausts are essentially a variation on individual exhaust systems. These exhaust systems have an identical arrangement as a single exhaust like a muffler, converter, and one headpipe – except they have two exhaust tips that exit from the muffler. This style doesn’t have performance benefits but a few hot rodders like the double tips to add performance.

  • Exhaust Type

The three primary forms of exhaust systems are axle-back, cat-back, and header-back. It depends on what type of E46 M3 exhaust system you prefer.

For many factors, the Cat-back system is the most common exhaust from several. Its mechanism is a relatively quick improvement to unlock the gas supply. This result is substantial power gains, even though the correct quantity of power depends on the rest of the stock exhaust compounds and the catalytic converters’ configuration.

The free exhaust flow will also add to your engine’s performance, which increases the fuel economy. This Cat-back system often emits more aggressive notes of exhaust and usually is emission-legal since catalytic converters continue in operation.

An axle-back system provides a rear-axle exhaust mechanism. Although the cat-back system produces more strength, the alternative of an axle-back course has several benefits. An adequately engineered axle-back exhaust offers power advantages over inventory exhaust and less costly than the equivalent cat-back system. This system is more comfortable to mount and can supply the desired output exhaust sounds. 

Frequently Ask Questions

  • How will you know the actual size of the E46 M3 exhaust?

Answer: The fast and straightforward way to calculate the pipe’s diameter from headers to mufflers is to revert to the old thumb rule, which requires one of the total pipe diameters in the entire system for every 100 HP. For instance, a 500 HP motor requires a 2.5 inches dual exhaust.
