Hello,
New member to the boards and the MB hobby as a whole and these boards have been extremely helpful. I'm currently purchasing components for my first build. I've picked up one of the 49CC HS-142 4-stroke kits, a cruiser style bike, new front & rear brakes, etc.,
I have a question about "after-market" exhaust modifications that I've been reading about on these boards. I've decided to go with the flexible exhaust set-up seen in several threads both for the versatility of placement on the frame and the reported performance boosts to torque.
Some old, dead but relevant threads:

In threads on these systems it states that the length of the system is critical to its performance with the ideal length of the exhaust for a HS motor being 28.5". However, as overall noise is a factor for me, I would also like to attach some type of muffler to the end of the system. So my question is, do I need to include the length of the muffler within this 28.5" measurement or do I just need a 28.5" flexpipe and then I can attach whatever muffler I pick? And for mufflers, are there specific styles/types that are the most efficient at noise reduction?
Thanks for any input
