Are Custom Motorcycle Exhausts Legal in India? Guide, Brands & Prices

Custom exhaust systems are a popular way for riders to improve sound, performance, and style. However, in India, modifying a motorcycle’s exhaust is not as simple as just bolting on a free-flow pipe. Riders must consider legal noise limits, emission norms, and safety standards before upgrading their exhausts.

Legal Status of Custom Exhausts in India

Under Indian law, any modification that alters the stock exhaust system can be considered illegal if it results in noise above the permitted limit or removes required components like baffles or catalytic converters. Traffic officials across cities including Coimbatore and Mysuru have been enforcing rules that prohibit silencers producing more than 80 decibels. Riders with modified exhausts can face fines, seizure of components, or even confiscation of the bike until a compliant silencer is reinstalled.

This means that while enthusiasts may want louder or sportier exhausts, they must ensure their upgrades remain within Motor Vehicles Act noise norms and do not interfere with emissions equipment.

Aftermarket Exhaust Brands Popular in India

There are several aftermarket exhaust brands that riders consider — but not all are officially road-legal without maintaining the required noise and emissions standards.

1. Akrapovič

Akrapovič is a premium international exhaust maker known for high-performance systems that improve power and reduce weight. Indian retailers list Akrapovič systems for many bikes at prices ranging from around ₹50,000 to ₹1.5 lakh depending on type and model.

While Akrapovič delivers top-tier quality and sound, riders must still check whether a specific model meets India’s noise regulations before use on public roads.

2. Red Rooster Performance (RRP)

Red Rooster Performance is a well-known Indian exhaust brand with 17+ years of experience supplying performance systems for Royal Enfield and other motorcycles. Their products often use high-grade SS304 stainless steel and are designed to balance increased torque and distinct sound with durability.

RRP exhausts sometimes include removable DB killers, which allow riders to reduce sound output — a helpful feature for staying within legal sound limits on Indian roads.

3. Khalidaro Exhaust – Made for Practical Indian Riding

Khalidaro Exhaust has grown popular among Royal Enfield and retro motorcycle owners. The brand focuses on a deep, classic tone rather than extreme loudness. This approach makes Khalidaro a practical choice for daily riders.

4. AEW India & Barrel Exhaust (Aftermarkets)

Brands like AEW India also offer slip-on systems for bikes such as the Himalayan 450, crafted to improve flow without excessive noise. Meanwhile, companies like Barrel Exhaust stock performance pipes (e.g., ~₹20,999 for a slip-on for certain models).

OEM and Performance Exhaust Prices in India

If you want improved performance without risking legality issues, choosing manufacturer-approved or well-engineered aftermarket options helps.

Here are some prices of popular Royal Enfield exhaust upgrades available in India:

• Red Rooster Astral PRO Exhaust (Super Meteor 650) – ~₹22,150
• Red Rooster Stellar Exhaust (Interceptor/GT 650) – ~₹20,100
• Performance Headers for 650 twins – ~₹14,990
• Rumbler-style exhausts for 350s – ~₹10,000
• Khalidaro slip-on range – ~₹6,500–₹12,000 (varies by model)
• Slip-on exhausts for various RE models – ~₹17,990

These parts offer options up and down the price scale, from performance-oriented systems to styling-focused silencers.

Tips for Legal & Safe Exhaust Upgrades

If you are considering an exhaust change in India, here are key tips to stay compliant:

1. Check Decibel Rating: Ensure the exhaust stays below 80 dB on public roads.
2. Retain Catalytic Equipment: Do not remove or bypass the catalytic converter required for BS6 emission standards.
3. Use DB Killers: Removable inserts help keep noise within legal limits.
4. Professional Installation: A qualified mechanic can ensure proper fitment and avoid leaks or performance issues.
5. Documentation: Keep receipts and specifications with your bike; traffic police may ask for compliance details.

Conclusion

Custom exhaust upgrades can transform your motorcycle’s sound and performance, but legality matters in India. Modifications that make your bike louder than permitted or tamper with emissions gear can attract fines or enforcement actions. Choosing reputable brands like Akrapovič or Red Rooster Performance — and using noise-control features — helps you enjoy a better riding experience while staying lawful and safe on Indian roads. However, modification or any OEM part alteration is not permitted in India, and even if the sound remains within the allowed dB level, you may still be penalized simply for altering the original component.
