It would create so much exhaust gas turbulence and an overall reduftion in exhaust gas velocity. In short you would lose a lot of power and the bike would run rough.

It was 48mm OD if I recall correctly.

Get a different bike, or a scooter. You'd have to add more restriction to reduce the noise further and in turn lose power.

The point is better sound, what other point would there be? No issues with engine management, no check engine lights and no strange behaviour. Engine revs a little more freely and there was a vibration around 3.5-4k which seems to less pronounced now as well. Fuel consumption seems slightly beter to. None of these were the reason though, other than hearing that beautiful v-twin sound and still keeping the stock look. For now. Most importantly, because I can...

@@FrancoisRouxChannel ok thx. I had an china aftermarket exhaust that was very simple build, and after installation i had problems with the engine some as clutch slipping and power reduction. The exhaust made a better sound but wasnt performed for the V strom some how.

Yes, there's 2 other videos after this one on my channel, which gives the before and after sound.

@@FrancoisRouxChannel it hard to judge thru the videos , does it make it much louder? is it worth doing the mod? thanks

Hi Jason, it makes it louder, but not excessively. Gives it that nice low down V2 bark and at speed it's only slightly more audible than standard. I think the mods is worth it as some of the vibrations around 3k became much less pronounced and the bike to my seat of 5he pants pulled much cleaner through the upper rpm ranges.
