Exhaust, idle musings about mods and effects
Posted: Sat Oct 16, 2021 6:04 am
Hi everyone
Seeing as my exhaust is off I've been wondering about modifications....
So the muffler is pretty large, and I've seen some mercedes car mufflers used as a slimline alternative. Making a 2 pipe into one after the heat exchange is no problem, so the world is my oyster. Oh really, we may say....
Replacing the muffler may well affect the flow of exhaust gasses, and so
1) might that require messing with carbs set up for stock? eg replacing jets, or worst case increasing exhaust air flow so much that the carbs begin to underperform?
2) in the context of one of the mercedes muffler replacement, I read something like this (a long time ago, and I cant see this in the forum on doing a search here) there was talk of increased backpressure, and mention that an increase in backpressure was not a bad thing for a pinz petrol engine. Really?
Can anyone enlighten or guide me around these topics please?
Thanks
Mark
