Watch Video: Yamaha R15 With Royal Enfield Bullet 350 Exhaust

The bike is louder now, but loud does not mean better

The two-wheeler modification culture in India is very interesting and exciting, but more often than not, it also defies logic, and is unsafe. One such foolish modification that the internet has brought to us is an as-modern-as-it-gets Yamaha R15 V4 flaunting an old-school-cool peashooter exhaust from the Royal Enfield Bullet 350.

Sure, at first you would be interested in this unique combination as it definitely stands out. And that is a good thing, as you can identify it and stay away. That’s because exhausts have a specific profile that matches the design of the engine so that it vents the gasses out effectively. 

By changing up the exhaust, what you do is put the bike's engine and valves at risk as there will be a lot of residual unburnt gas that may be trapped within the exhausts. While it is harmful for the engine, it is also harmful for the environment as well. Oh also, the exhaust setup on this R15 is a free flowing one, which means that the emission and sound levels are higher than what’s legally allowed. So this exhaust setup is also illegal and will definitely get you in trouble with the cops.

Now lastly, sportbikes generally have a shorter and upswept exhaust setup for better cornering clearance. With the Bullet 350 exhaust on the R15, the clearance has gone for a toss, and the exhaust will definitely scrape while cornering. The ground clearance is compromised as well, so when the bike goes through a pothole or a speed breaker, it will scrape as well.

We understand that modifications can be fun, but if that compromises the performance and practicality of the bike, and/or harms the engine, it is definitely not worth it. In addition to that, if it is illegal, then you should stay away from such a modification.
