I ordered my bbk tonight and I am trying to find a free flowing exhaust. What do you think of a 54 dollar multi color from ebay and what would be a range of jets likely to suit me with uni, cdi, coil, bbk 72cc, and free flowing exhaust?

One step at a time my friend.
Please, DO NOT throw a bunch of random parts on and expect it all to work reliably. Any cheapo e-bay exhaust will work just fine but,
You will need to re tune the engine several times to suit your needs after the install. A BBK may be all you want/need.
A "sleeper" is more fun anyway JMHO.

Many are just tiny OE Head pipe plated, The free flow fart can will help, but make positive sure it a for real deal. I'n the end it is Noisy. I don't care for mine too much. post a link of the system your looking at |

Just to second what P-Guy said. I made the same mistake - bought a "performance" exhaust header. It looked nice. Chrome. Fat pipe. BUT --- only to find out when it arrived the first 6 inches was just the skinny, OEM diameter pipe that caused pretty much the same back pressure and restriction that the oem pipe caused. Couldn't tell except by looking into the pipe from the flange end. P-Guy posted some perfect pix explaining the problem in this thread: www.dansgaragetalk.com/topic/81-150cc-stock-head-pipe-woes/No matter WHAT you do to your muffler you will not overcome the restriction caused by this teensy first 6 inches of exhaust header. |

Oops, I guess that link I showed the seller sold out of those ones. But like a dozen other sellers have the same kinds for like 80 bucks or so. Just search gy6 exhaust or something on aliexpress. Id check the seller ratings and stuff to find a good dealer

Right on, right on all true dat. Ive spent hours and hours shopping and looking very closely at the head pipe product, most are fake. |

So I just need to figure out the carb jetting with exhaust and bbk from here.
my bike has tall gears already as it is a long case with a 744 belt and 13inch rear. Not gps confirmed but.... chinameter was way past 50. Im going to take a ride with gps right now.

I thought it was " running like a top" ?!
Back preassure is a thing---- Just sayin.
Free flow just means there is no baffle...

The price is nice. I wonder with No Picture up the but of the fart can if its Free-Flow? Ive seen so many of a fart can inside a fart can heavily baffled and are No Better than the OE System. Buyer Beware. |

Scooter is running fantastic aside from the belt I just shredded... damn it!
bbk will be here this week but I may wait to instal it until I have this belt crap figured out. It doesnt seem to have been able to rub on anything and I am lost as to why it died the way it did.

And yeah no pic of the actual muffler opening has me weary. But if I had to open up that one versus my stock one with a higher flow header, I would rather do that one.
