Heran 22mm Universal Motorcycle Mini Exhaust Muffler Slip On fits Most 50cc 80cc 2 Stroke Bike Gas Engine Motor Parts Motorcycle,Dirt Bikes,Scooters,Racing

Never-mind the bad reviews, this is high quality muffler that is made from 304 stainless steel inside & out and everything that comes with it is made from 304 SS.If you want the muffler quieter just add a baffle to the inside.If you want a Ultra Quiet Hunting Vehicle just add it on to your ATV or motorcycles exhaust system. Just connect it behind your muffler that is already on your vehicle and you won't have any more exhaust noise. If your stock exhaust is real loud you may need to add a baffle to the inside of the new muffler to help make it quiet.Now you have a stealth hunting machine.If you want super stealth machine pull that gas engine out and install some batteries with an electric motor.

35mm ID (varied .5mm between the 2)38mm OD (only at tip of taper)40mm OD (usable)Looks the part, but inaccurate dimensions make it worthless for my applicationFibers from baffle packing are stuck welded under tab

Poor quality manufacturing.sending back

Put on 300 cc quad. Welded on, sounds great with or without the baffle

The media could not be loaded.  Just what I needed

Looks good but just another cheap Amazon exhaust. No baffle and no back pressure, made my sv650 feel like a 250. It’s just a straight pipe

Good sound but the inlet size says 1-1/2” but it’s actually 1-3/8” had to cut it and open it up more to make work.

Installed on a vintage xr75 and a China pit bike. It’s not a bad sounding muffler at all and for the price you can’t go wrong

Sur mon tracteur bolens j'aime beaucoup le son pas trop fort
