Banana pipe modification (make it less crappy?)

[HumanPerson]

And please don't go with one of those bikeberry speed demon expansionchamber/muffler.
They have at least 6 inches of pipe sticking into the chamber from above, i had cut one open and seen that and fell on the floor.

Look it up its a pipe they call it a voodoo it has a screw on part that mounts the banana to the exhaust.

This thread saved me $35-40...that Chinese banana pipe is GARBAGE!

I would rather run a drilled baffle stock muffler than that.

You know the threaded banana with a long header

Yeah... no. I got the banana pipe that has the end at an angle pointing to the ground. Well.... The metal part that is welded to the pipe (The part that has the screw holes in it) is welded on slightly bent. The left hole for the screw is almost at the top of the metal, not in the middle. The right one is center. The weld marks come out about a centimeter. The diameter of the exhaust pipe at the bottom is about 2/3 the stock pipe. Shame on quality control... I mean it was just 8$ so.

I have the banana pipe and have used the stock exhaust. it works ok I think and I notice an increase in bottom end torque and have not noticed any top end speed lost. one thing that is nice with it is how it stays close to my frame and I can ride over curbs and trees and stuff and nothing hits my pipe like a stock exhaust . to each their own. I wasn't going to spend 1/2 the price of a motor for an expansion chamber to eliminate my exaust getting knocked off by something I am cruising over. ( yes I have done this and it ruined my exhaust pipe and bent the studs and tore the gasket and am lucky it didn't crack the jug

I did this a few years back to show folks and warn away from it's use yet many still bought it. There is a different one out there now though that has no internal baffles and the little stinger comes out at an angle,the header is still too small in dia and length but it's an improvement on the original.

Why would they make it that way? How can you get any benefit from the expansion with pipes inside like that? I'm confused.
