About Yoshimura GP Magnum Exhaust For Honda Monkey.

Introducing the GP-Magnum Race Series retro up-pipe from Yoshimura.

With the Monkey's late 60's early 70's retro styling, the GP-Magnum fits the bill for those builders and racers that only will settle for that classic Yoshimura JDM style.
There are two GP-Magnum mini systems available, both are handcrafted by our sister company in Asia for Yoshimura R&D exclusively for the US market. Both use stainless steel construction throughout the system with two sleeve options. Stainless polish finish or titanium that displays a one of a kind bluing effect and topped off with a old school Yoshimura badge.
The GP-Magnum removes over half the weight and replaces it with nothing but power, Yoshimura exhaust note and a retro feel that only Yoshimura delivers.
Nobody knows small bore like Yoshimura!
Yoshimura right side cover is available separately.

    I ordered the titanium version for my Honda monkey and it’s looks awesome. Very nice quality, install is super easy and it sounds mean. The low volume insert that came with it did not fit so I had to grind it down a bit and get it in but even then it didn’t change the volume just the tone. Made the bike 10 times more fun to ride.
