The Best exhausts for the Honda Grom
If you ask anyone what makes or breaks a motorcycle, odds are they’ll tell you it’s the exhaust. Besides giving it a new look, aftermarket exhausts add a lot of character to the bike. And when your bike’s engine is a 125 cc single cylinder, you’re gonna need all the help you can get to make it go VROOM. But with so many options to choose from, which is the best exhaust for the Honda Grom?
Add-ons like aftermarket exhausts and headers can result in some pretty significant power gains. With lightweight machines like the Honda Grom, even small boosts can be quite noticeable and improve the riding feel. But which exhausts actually make a difference?
We considered all of the exhaust systems available on the market for the Honda Grom and shortlisted only the ones that made our hearts flutter like butterfly valves. Read on to find the perfect exhaust for your Grom.
LeoVince GP Corsa EVO Slip-On Exhaust
Overall best Honda Grom exhaust
LeoVince makes some of the most desirable parts and exhausts for motorcycles. It only makes sense that they also produced our top pick for Honda Grom exhausts. The ‘GP Corsa EVO Slip-On’ embodies the very essence of custom exhausts: improvements in form and function, high-tech construction and materials, and most importantly, a remix of your motorcycle’s boring exhaust sound. It really is the epitome of modern exhausts.
A lightweight stainless steel link pipe adds a bit of flair to an otherwise understated look. Carbon fiber dominates the muffler sleeve, accentuating the overall matte look without making it too flashy. The endcap is constructed from technopolymer, helping round out the design and keep it subtle. The matte aesthetic is thanks to a special assembly process, whereby each individual piece is cleaned before being put together.
With such close attention to detail, you might think the ‘Corsa EVO’ is all about the looks. On the contrary. Lightweight construction means legitimate weight reduction over stock. The use of CAD in the design process makes sure you get a bespoke fit for your Grom. Power output also benefits from this exhaust. While a slip-on will never yield the most dramatic power gains, this one does offer increased exhaust flow and a more responsive feeling motorcycle.
But what about the sound? LeoVince makes some truly eargasmic products and this is no exception. It completely transforms the lackluster stock sound to a more pleasing exhaust note. You will find that the bike is louder though not obnoxiously so. Deeper, tighter bass, that recalls MotoGP rather than city commuter. It breathes new life into your bike and makes it sound fantastic, with every twist of the throttle producing a more pronounced, raw sound than normal. It definitely has our seal of approval.
