The cheapest way is to cut the muffler off at an angle so the exaust isn't blowing on your pedals making them slippery...So I was looking to throw on an expansion chamber on my bike, but there is a ton of knock-off china crap floating around fleshed out with convincing marketing.
I read on another thread here that I the MZ65 is the real deal and to avoid bananas and knock offs:
I just got a... Pic below and wanna add power... Is an expansion chamber muffler best or is there something else I can do. Already has a performance carb setup... And which rear sprocket teeth is best for top end speed. I have a 7speed. Not afraid of pedaling. Pic on profile. Currently running...motoredbikes.com
But I am not 100% up-to-date and into the culture yet, so I don't know a reliable option to order that isn't A. Fake B. Crap and C. Gimmick.
For example, take a look at this:
Tempting me, but after comparing it doesn't look right - almost like it is a knock-off and not going to actually perform right due to tube diameter etc...
I want to keep it stock as possible minus plug, jet, exhaust, carb adjustments. People make it seem like "YOU'RE GOING TO DOUBLE YOUR PERFORMANCE BRUH!" with an exhaust upgrade, so I am highly tempted to try it out.
Any suggestions on one I can order right now that is vetted or a true MZ65 style?
Grab a 60-80 spread, then you dont need to worry. Make sure you dont get the wrong nt jets. Bofeng uses these https://www.amazon.com/gp/product/B08CNDTMRT/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1Assuming this kit came with a 70 jet on the stock carb - are you saying I need more or less? Looks like I can grab a set off amazon that ranges.
