custom exhaust on 49cc 4 stroke

ridicule if you must, it looks like crap and its rigged, but its temporary just to see if it would work, and it does, i get alot more torque and 5kph more top speed! more to come.

if you put on a straight pipe that starts from were the exhaust exits the motor then curves to the back of the bike frame would you have to worry about it not having enough back pressure?

@The88drunkredneak it would depend on the size of your tubing, i pipe that is the size of my current header gives you almost no back pressure. i ran it with my stock muffler with the baffle removed. it was louder and had less high rpm power. for me atleast i had to find the right back pressure to give me the most power. thats why i have a can with holes drilled in it! lol. if you run it for too long of a time without sufficient back pressure your exhaust valve can burn up
