Important Information
There are a large number of counterfeit and imitation Austin Racing exhausts currently on the market.
Our genuine Austin Racing DB Killers are designed specifically for authentic Austin Racing systems and will not fit counterfeit exhausts. Unfortunately, we cannot guarantee compatibility with non-genuine products.
For GP1 and V3 inserts, we may include two different mounting screws. Depending on the age of your muffler, the bolt size may have changed during production updates. Once you determine the correct screw for your exhaust, simply discard the unused screw.
All exhaust systems are supplied without DB Killers, and they must be purchased separately.
Please also note that some exhaust systems are not capable of housing a DB Killer due to their internal design, including:
- RR Tip systems
- Certain low-capacity motorcycle systems
Always check compatibility carefully before ordering.
