How to Choose and Buy a Motorcycle Exhaust System
The right motorcycle exhaust depends on three decisions you make before adding anything to a cart: how much of the system you're replacing (slip-on, mid-pipe, or full system), whether it's confirmed to fit your exact bike, and whether your fueling can handle the change. At a retailer like Moto Wheels, which stocks exhaust alongside brands such as Akrapovic, Arrow, Termignoni, LeoVince, Mivv, Spark, Zard, and HP Corse, the practical work is matching your bike to a SKU and understanding what else the swap triggers. Get those three right and the purchase is straightforward; get compatibility or fueling wrong and you'll be dealing with returns, warning lights, or worse running than you started with.
Step 1: Decide how much of the exhaust you're replacing
| Type | What it includes | Typical effect | Install difficulty |
|---|---|---|---|
| Slip-on | Muffler/canister only, clamps to the stock mid-pipe | Sound and weight change; minimal power gain | Low — usually bolt-on |
| Mid-pipe / link pipe | Replaces the pipe between header and muffler, often removes a catalytic converter or flap valve | More sound, some flow gain, may need fueling adjustment | Moderate |
| Full system | Header, mid-pipe, and muffler as a matched set | Largest flow and weight change; usually requires a tune | High — often needs fairing removal, gaskets, and re-mapping |
If you mainly want a better sound and less weight, a slip-on is the low-risk choice. If you're chasing flow — for example, after intake and ECU work — a full system is the coherent purchase, but budget for a dyno tune or flash.
Step 2: Confirm fitment before anything else
Exhaust fitment is model-, year-, and sometimes trim-specific. A pipe listed for a 2019 model may not clear the swingarm, center stand, or belly pan on a 2021 refresh of the same bike.
Check, in this order:
- Exact model, year, and displacement — not just the family name.
- Mounting points and header diameter — slip-ons must match your stock mid-pipe diameter and flange type.
- Accessory conflicts — center stands, luggage racks, lower fairings, and aftermarket rearsets can interfere.
- What's in the box — some systems ship with gaskets, springs, and hardware; some don't, and you'll need to order them separately.
Moto Wheels organizes browsing by both Shop by Bike and Browse Brands, which is the fastest way to narrow to parts listed for your machine rather than scrolling a general exhaust category.
Step 3: Pick a material based on what you actually care about
- Stainless steel — heaviest of the three, most resistant to dents and road salt, usually the least expensive. Good default for street bikes.
- Titanium — noticeably lighter, runs cooler to the touch, produces a sharper/higher tone. Costs more and dents more easily.
- Carbon fiber — lightest canister shell, distinctive look and deeper sound, but the finish can fade or yellow with heat and UV over time.
Weight savings from a full titanium system can be significant versus stock steel, but the sound and heat characteristics matter more to most riders than the grams. Pick the material you'll be happy living with, not the one with the best spec sheet.
Step 4: Plan for fueling
Changing exhaust flow — especially removing a catalytic converter or exhaust valve — changes how the engine breathes. Common symptoms of not addressing it:
- Check-engine light from the O2 sensor or exhaust valve
- Deceleration popping or backfiring
- A lean condition at part throttle, or a flat spot in the midrange
Options range from a plug-in fuel controller to a full ECU flash. Which one you need depends on how much of the system you changed and how your bike's ECU is set up. A slip-on on many modern bikes runs fine without changes; a full system almost always wants a tune. Confirm this for your specific model before buying, because it affects your total cost.
Step 5: Understand the purchase terms before ordering
Large, heavy items like full exhaust systems have logistics that small parts don't:
- Shipping — Moto Wheels advertises free shipping on orders over $149, which most exhaust systems will exceed. Confirm carrier and delivery expectations for oversized items.
- Returns — check whether an installed or opened exhaust can be returned. Many retailers restrict returns on installed parts, so inspect the system for damage before mounting it.
- Warranty — manufacturer warranty terms vary by brand; keep your order confirmation.
- Order confirmation — Moto Wheels notes a temporary technical issue and asks customers to check spam/junk folders after placing an order, so verify your confirmation email arrived before assuming the order failed.
Quick decision path
- Want sound and less weight, low hassle → slip-on, stock fueling, verify fitment only.
- Want flow and a matched system → full system, budget for a tune, confirm gaskets and hardware are included.
- Unsure about your bike's ECU behavior → start with a slip-on, or ask the retailer which controller/flash they recommend for your model.
The purchase itself is the easy part. The three decisions above — scope, fitment, fueling — are what determine whether the exhaust you buy is the one you actually wanted.
