All Barrel exhausts are direct bolt-on fitment — no cutting, no welding, no frame modifications required. They use the stock mounting points and come with all necessary hardware. A basic mechanical install takes 30–45 minutes at any service centre or at home with standard tools.
Slip-on exhausts generally do not require ECU remapping and have minimal impact on fuel mapping. For full system exhausts, a tune is recommended for best performance. Regarding your bike's warranty — aftermarket exhausts can technically void emission-related warranty claims; however most service centres proceed normally for mechanical issues unrelated to the exhaust. We recommend checking with your dealership if this is a concern.
Most variants of the same model share the same exhaust fitment — for example, RE Classic 350 (S, Chrome, Signals, Dark, Halcyon) all use the same mount. However some year or variant changes can affect fitment. If you're unsure, share your bike model, variant, and year on WhatsApp and we'll confirm before you order.
Product & Specifications
Barrel exhausts are built from high-grade stainless steel with precision TIG-welded joints. The canister uses heat-resistant materials designed for long-term durability under high-temperature conditions. Finish options include brushed stainless, black ceramic coat, and chrome depending on the model.
Slip-on: Replaces only the muffler section. Easier to install, more affordable, great sound upgrade with minimal performance change. Best for riders who want the tone without the complexity.
Full system: Replaces the entire exhaust from the header pipe to the muffler. Significantly improves exhaust flow, adds noticeable performance gains (3–8 BHP depending on model), and delivers a louder, more aggressive note. Requires a professional install and ideally a tune.
