Getting Ready How to Install M Performance Exhaust on M235

This section is all about preparing yourself and your car for the actual installation. It covers the essential tools you’ll need, the parts you should have on hand, and how to safely get your M235 ready for the job. Think of it as laying the groundwork for a successful exhaust swap.

We will go over the specific M Performance exhaust parts you need to make sure you have everything before you start.

Gathering Your Tools and Parts

To successfully How to Install M Performance Exhaust on M235, having the right tools is super important. This makes the job go smoother and safer. You won’t want to be halfway done and realize you’re missing a key wrench.

A good set of socket wrenches, usually metric, will be your best friend. Don’t forget extensions and a universal joint for those hard-to-reach bolts. You’ll also need some penetrating oil to help loosen rusty bolts and exhaust hangers.

Having a torque wrench is also vital to tighten everything to the correct specifications, ensuring a secure fit and preventing leaks.

• Socket Wrench Set Metric: A comprehensive set with various sizes, including 10mm, 13mm, 15mm, and 17mm sockets, is essential for removing and installing exhaust components. Look for a set with both standard and deep sockets.
• Torque Wrench: This tool ensures you tighten bolts and nuts to the manufacturer’s specified tightness. Overtightening can damage parts, while undertightening can lead to leaks or parts coming loose. A click-type torque wrench is generally recommended for accuracy.
• Penetrating Oil: Exhaust systems can be exposed to moisture and heat, leading to rusted or seized bolts. A good penetrating oil, like WD-40 or PB Blaster, helps to loosen these stubborn fasteners, making removal much easier.
• Jack and Jack Stands: Safety is paramount. You’ll need a reliable car jack to lift your vehicle and sturdy jack stands to support it securely while you work underneath. Never work under a car supported only by a jack.

Inspecting the M Performance Exhaust System

Before you begin the installation process, take a moment to unpack your new M Performance exhaust system. Carefully inspect all the components for any signs of damage that may have occurred during shipping. Check each pipe, muffler, and hanger bracket.

Ensure all the necessary gaskets, clamps, and bolts that came with the kit are present and accounted for. This pre-installation check saves a lot of headaches later on. It’s also a good time to familiarize yourself with how the new system is designed to fit.

Preparing the Vehicle

Safety first! Before you even think about touching your old exhaust, you need to prepare your M235. Find a flat, level surface to park your car.

Engage the parking brake firmly. Using your car jack, lift the rear of the vehicle high enough so you can comfortably work underneath it. Immediately place jack stands under the designated support points on the frame.

Give the car a gentle shake to ensure it’s stable on the stands. Never get under a car that is only supported by a jack. Having enough clear space and good lighting will make the entire process much more manageable and safe.

Removing the Stock Exhaust System

Taking off the old exhaust is the first major step in the installation. This part requires patience, especially if the bolts are a bit rusty. We’ll guide you through unbolting the sections and carefully lowering the old system.

This process is key to making space for your shiny new M Performance exhaust. We will also discuss how to safely handle the old exhaust system once it’s removed.

Locating Exhaust Hangers and Mounts

Your M235’s current exhaust system is held in place by several rubber hangers and metal mounts. You’ll need to find these to release the old exhaust. Most cars have hangers located along the length of the exhaust pipes and near the muffler.

They are usually simple rubber loops that slide onto metal posts attached to the car’s undercarriage. Sometimes, there are additional brackets or heat shields that need to be removed first. Identifying all these points is crucial before you start unbolting.

Disconnecting the Exhaust Sections

The exhaust system is typically made up of several sections. You’ll likely need to disconnect the muffler from the mid-pipe, and potentially the mid-pipe from the downpipe or catalytic converter. Look for clamp connections or bolted flanges.

Use your socket wrench and penetrating oil to loosen these fasteners. For clamp connections, loosen the bolts on the clamp until it can be spread apart. For flange connections, remove the bolts and nuts holding the two sections together.

Be prepared for them to be tight.

Safely Lowering the Old Exhaust

Once all the connections are loosened and the hangers are ready to be released, it’s time to take the old exhaust down. It’s a good idea to have a helper for this part, as exhaust systems can be heavy and awkward. Carefully slide the rubber hangers off their posts.
