Slip-On Exhaust Systems

A slip-on exhaust typically changes the sound, weight and look at the rear of the vehicle. It replaces the rear muffler and fits onto the existing pipe. That makes it a good choice if you want to upgrade your car, motorcycle, scooter or UTV without replacing the entire system.

What a slip-on exhaust replaces

A slip-on exhaust is clamped onto the pipe already fitted to the vehicle. It typically replaces only the muffler and, in some cases, a link pipe. An axle-back system replaces the pipes from the rear axle back, while a cat-back system replaces everything after the catalytic converter. Slip-on is therefore the least invasive option. The power gain is typically limited, while sound, weight and appearance change more. If you need to replace more of the exhaust, take a look at our other exhaust systems and kits.

How to choose a slip-on exhaust

• Fitment: Model year and model are stated in the product name, e.g. BMW M2 (G87), Porsche 911 (992) or Polaris RZR XP 900. Also check whether a link pipe is included.
• Material: Titanium, e.g. in the Akrapovic Slip-On Line, typically weighs less than stainless steel. An example of stainless steel is the Remus slip-on for the KTM 1290 Super Duke R.
• Tips: Several products are marked “Req. Tips”. For these, the tips must be purchased separately.
• Sound: Sound level and sound character depend on the muffler's design and on the vehicle, not just on the pipe diameter.

In this category you will find brands such as Big Gun, Remus, Vance and Hines, Akrapovic and QuadBoss.

Installation and inspection

Installation typically requires only standard tools. However, new gaskets and clamps may be needed, and you can find them among our exhaust installation kits. Whether a slip-on is road legal and can pass inspection depends on the product and the vehicle. So check the E-mark and sound level for the specific part number. Retighten the joints after the first few rides.

Frequently asked questions

What is the difference between a slip-on and an axle-back exhaust?

A slip-on typically replaces only the muffler and fits onto the existing pipe. An axle-back covers the piping from the rear axle back. Where the line is drawn depends on the vehicle and on the manufacturer's design.

Can a slip-on exhaust pass inspection?

That depends on the product and the vehicle. Check whether the specific part number has an E-mark or other approval for your exact model, and whether the sound level meets the requirements. Do not assume that the entire series is approved.

Does a slip-on exhaust add more power?

Typically only a little, because the rest of the exhaust remains unchanged. The biggest difference is often in sound and weight. A larger power gain usually requires more changes to the exhaust and possibly an engine management remap.
