I ordered 2 for my 1 inch header exhaust and these were not even close to firing over the tip.
As its name implies the “silencer” tones down my Honda GX 270.
I am very pleased with the mini91 silencer. Price was great. It looks great. It also made it a lot more quiet. I was shocked at how small it is. A very good clamp comes with it. There was an additional clamp in case you race and put a teather on it. I have installed a jetted carb a cold air filter and open muffler pipe prior. The muffler pipe was loud probably too loud. The mini91 is a perfect balance of little to no back pressure but calms down the decibels. It was delivered to my mailbox and damage free . Thank you GoPowerSports for giving me great selections to make my kart mine. Ps I would add photos if it was an option
Awesome. Takes the sharpness sounds off a straight header pipe. Not too loud but still sounds gnarly. The bummer is that shipping costs to Canada hurts plenty.
Very simple design and construction, seems over priced.
Has everything you need from upgrades and mods for mo power. Silence was just the right fit it was all i needed i didnt want to buy a whole new exhaust.
This fits on the end of my generator pretty nicely. I did have to add some wadding to achieve the quieting effect, however.
Does not reduce noise enough for the non calibrated ear to notice a difference
The problem is it restricts the power of the motor, not good
