Mivv: Slip-on exhaust for EX300
Geetings all. Thank you for the forum. Please allow me to add another thread on aftermarket exhausts. I've purchased a Mivv "Storm" slip-on exhaust from Italy. Link to website below:
https://www.mivv.com/en/products/k-0...ja-300-2013-2/ The website has a dyno chart showing the performance of this product, a technical sheet and a schematic diagram. This slip-on meets Euro 3 standards for Db level, CO2 and CARB standards as well. Amazon or Ebay price for Stainless Steel version about $250. Comes with midpipe, support strap and all hardware needed to install. It's Italian made in Rimini and it is IMHO beautiful in design detail and craftsmanship. Gorgeous. The heaviest aftermarket slip on muff I've ever handled, but still significantly lighter than stock muff. I'm impressed. Thanks for allowing me an opportunity to share my experience. I have the morning off and I'm heading to the shop for install. I'll post a follow photo and my first impressions. |

Yep, that's because dyno actually only measures torque and HP is calculated using HP=TQ*RPM/5250. However, while crossover is always at 5250rpms, if the scale of HP and TQ are different, this can shift the graphs to a different crossover (optical illusion). However, in the original graph, they are on the same scale, so yeah, something's wrong.

Greetings all. Thank you for your posts...
I rode a limited amount around town yesterday with the purty new muff. With the end baffle installed (by manufacturer w/rivet) it is as quiet as the O.E.M. item. Early next week I'll remove the rivet and baffle to determine how loud it it will be without.The Mivv muff installed easily with the nice hardware included (although the stainless steel bracket clamp has a mill finish which may scratch easily as you install) and it will allow for easier maintenance and cleaning in and around the swing arm and rear master cylinder. Of course, my boot heel no longer comes in contact with a muffler or shield. Overall more "in scale" with the EX300 and IMHO a nice looking replacement for the questionable O.E.M. item. |
