I got bored last week so bout a standard exhaust off a crashed bike for £40. Repaired the damage, removed the cat and straight piped it. Got decent result on the dyno too and sounds better now as the bikes way to quiet standard.

Was happy with another 0.75 to 1 bhp extra and much better top end and acceleration too. Now the bike still looks totally stock exhaust wise but has essentially a race can. Ill get the DB meter out tomorrow and see how loud it is now too but its not to much louder compared to my other bikes

Very cool video and info. If you did nothing other than modify the exhaust, your results may debunk some of the doubters that there's any power gains by doing so. Interesting for sure. Thanks for posting!

I was supposed it did all the power that we'll. I wasn't expecting a lot from it but only way to properly test these things is by using a Dyno. Do all my RnD using a Dyno. Only other mods on the bike are larger screen, honda heated grips and tucano Urbano appron. Engine , fuel system and wiring are all stock. Still getting 110mpg from it with the can mod too.vamootsman wrote: ↑Sun Nov 21, 2021 6:56 pm Very cool video and info.

I'm now trying to figure out if honda use a PAIR system on this engine now so I can delete it if so and get a proper A/F reading. Might contemplate then getting a piggy back ECU to try and improve the fueling on it.

I'm really tempted to fabricate a mandrel bent manifold for it next. out of 25mm and 30mm pipe to try and smooth the flow out a little better and try some different silencer designs on it. See what results I get from it. If a manage to get some time in the next couple months I'll do it. Currently on isolation because of covid
