This is SIP's answer to the BGM MRB Big Box Exhaust. Basically, the BGM MRB Big Box came out and eclipse the SIP road pipe in performance so they went back to the drawing board and beat it with this little number. Compared to a standard SIP road, you will lose some ground clearance but it's on par with the the Sito+ and the Big Box in that department. What that ends up meaning is that I wouldn't recommend you fit this to an 8" Vespa as it will fit but you might drag it over speed bumps and such. On 10" models this shouldn't be an issue.
So get the latest and greatest SIP road pipe and be the envy of all your friends. Perfect for stock or tuned engines!
