There are 100,s to choose from and all sorts of prices the choice is bewildering so a review by a user of a particular exhaust with a particular setup without the graphs and power curves might ease the load.just reply to the post.

The Naraku traffic stealth exhaust. Fitted to an 2004 Yamaha CS50,stock engine up jetted and a polini high speed variator. With the restrictor ring removed a 15mph increase over stock was more than enough for me but it seems to have a lot more to give.my scoot pulls from Rickover right through to 45mph with no hesitation or power surge at any given revs. On the center stand in my yard I had 70db at idle and 80db at Wot so yes you can hear it but the horses don't,t bolt. This one is my second the old one gave out after six years and 18,000 miles so I,d say it,s a quality product and well worth the cost Geoff   |

Yoshimura muffler with a custom stepped exhaust manifold to fit 150cc+ GY6 engines with a 7 or 8 inch fatty rear wheel. Originally made for Honda CR dirtbikes. Works very well and is loud enough to make motorists aware of my existence.(No db killer) Costs an arm & a leg, but i think it was worth it. Use with an aftermarket air filter for best results.
Ebay pick n mix exhaust system. Stepped exhaust manifold was $80, muffler has a db killer and was $45-$50. Worked on all my 150cc GY6 engines with enough clearance for a 7 or 8 inch fatty rear wheel.
The sound is neighbor friendly, like a 250cc scooter. I use this to setup new engine swaps.
