The good news is that we can see the camshaft is in relatively good condition.
The bad news is that we can see the camshaft. https://cimg0.ibsrv.net/gimg/www.mia...e406d6b0f2.png |

Hmm this is actually very neat. Using quarter wave to eliminate drone

This is just beautiful.

^ That's pretty clever.

Corsa's mufflers are all about 1/4 wave, application specific, with multiple chambers for various frequencies and an accordion design to make long wavelengths able to be packaged in a normal sized muffler envelope. My dad's vette had them and was near silent everywhere you'd want it to be and...not silent where you want it to be loud. My Grand National also used something similar, only a few slits in the pipe and that thing was quieter than the factory exhaust. https://cimg8.ibsrv.net/gimg/www.mia...8111cd70cc.gif |
This is the rare sight of a wine glass full of propane at atmospheric pressure. Propane has a boiling point of -42C, which is why you only ever see it in gaseous form. However, an enterprising Alberta Redditor was able to capitalize on the province’s ongoing cold snap and capture this photo at an outdoor temperature of about -43C.

Yeah they work well. I'm building one of those for my Wagoneer. I need to find whatever frequency app that guy is using because it's much nicer than the one I found.
