- Always replace your exhaust gaskets during an installation to ensure a leak-free seal that protects your engine's power.
- Decide between slip-on mufflers for quick sound upgrades or full exhaust systems if you want to modify your bike's power curve.

Frequently Asked Questions
Do I have to re-map my ECU after installing a new exhaust?
Yes, you should. Changing the exhaust alters the exhaust gas velocity, which changes the engine's requirements. Without a proper tune, you risk engine damage from a lean condition or excessive popping during deceleration.
Will a new exhaust void my factory warranty?
Harley-Davidson has strict rules about modifications. If the dealer determines that the new exhaust caused a specific mechanical failure, they can deny a warranty claim. Check with your local service department before you swap parts if you have an active factory warranty.
Is it difficult to install the exhaust myself?
If you have a decent set of metric and standard tools, you can handle this in an afternoon. The hardest part is often removing the old, rusted bolts from the exhaust ports. Use a penetrating oil the night before to save yourself a massive headache.
What is the benefit of a 2-into-1 exhaust system?
These systems are designed for maximum performance. By merging the exhaust pulses, they create a scavenge effect that pulls burnt gases out of the cylinder more efficiently. This results in a noticeable bump in horsepower and torque across the entire rev range.
Can I keep my original heat shields?
Most aftermarket exhausts come with their own custom heat shields. Because the routing and diameter of new pipes differ from the stock setup, your old shields likely won't fit. Always ensure your new kit includes high-quality heat shielding to protect your legs from burns.
