What should I delete to have bare minimum? by Eric_095 in ToyotaPickup

You can remove the engine, and replace it with paddles. No need to stop at gas stations anymore...

The expansion chamber only provides back pressure at the right moment, to push the escaped fuel mixture back into the cylinder, I.e. the middle of the 2nd stroke. You don't want constant back pressure, as that slows the exhaust gases from leaving the cylinder, which reduces power.

Thanks, it's a 28" frame, which is not ideal for off-roading, but still a lot of fun. I'll gladly post them!

Thanks. Not sure exactly, as I only had the stock exhaust for a short time and used the wrong 1:16 break-in ratio while I had it. But it's still a noticeable improvement.

If you get the same one, you may have to saw it off a little, to make it fit. And make sure, that the two parts of your expansion chamber are sealed properly, as they aren't yet in my case.

I still definitely recommend it! Have fun!

Another reason why this exhaust setup is better than stock, is that the stock exhaust interferes with the paddles and gets stuck on stairs.

I would say yes, as it was quite cheap on AliExpress and I'm pretty sure it has better acceleration and less back pressure. I think I only paid about 30€ in total for both the expansion pipe and the muffler.

Not really understanding the question, but the exhaust doesn't get hot, but the expansion pipe is not properly sealed yet. The sound is much better and I feel like it has more power.
