Actually many Chinese OEMs and suppliers are localizing in the US. The Chinese government is prohibitive of imports, but the business culture realizes the need for localization

1st gear: Good on China for putting the screws to Hyundai’s backwards purchasing model. Hyundai Purchasing sucks to work with. They seek only Korean mainland sources which drives quality down and cost up. They want to sell globally, but buy locally. Our economy will not tolerate that.

Back down or else what you stupid drippy dick son of a bitch?

No you dense motherfucker, that is the exact topic here. Does removing a muffler reduce pack pressure and increase horsepower. The answer is yes. The OP’s original comment that “Removing mufflers altogether doesn’t yield performance numbers” is false.

Again, not advocating everyone cutting off their mufflers, but OP said “Removing mufflers altogether doesn’t yield performance numbers.”

Can you find any evidence that an engine lost peak horsepower from an exhaust being too big?

But we’re not talking about pipe diameter, 2.5 to 3.0 on a 400 hp small block is a meaningless change, but what we’re talking about back pressure induced by the mufflers. Of which neither the thrush muffler or the magna flow is an example of a factory baffled piece. Both of them will create less backpressure than a…

on a 350 inch chevy, you will never lose power by going with the biggest exhaust you can.

All street mufflers restrict flow. A 4 inch race muffler might restrict only .5% flow vs a straight pipe.

You mean this one? where it shows muffler back pressure killing a bunch of power? back pressure is bad, always.

For peak torque perhaps, but not peak power. I cannot find a single engine dyno test where more peak power wasn’t made by reducing back pressure.

Ken,

Power =\= torque. Again, I’m not advising people not to run mufflers, just pointing out that it does in fact lead to a power loss.

Even the best perforated core mufflers have an impact on flow. I’m sorry but I’ve seen this guy’s engineered video and his job is to sell mufflers. While I agree a straight through, perforated core muffler has the least impact, it does not, and cannot flow more. If that was the case, they would run an individual…

I’m not saying it wont sound terrible. I’m just saying that it is factually inaccurate to say that it wont make any more power.

Is it general? Yes. Is it true? Yes. A small motor may lose some lower torque but will make power up top.

Yes, removing mufflers yields performance gains. Less back -pressure more power.

One of my good friends got a ticket on a completely stock Lamborghini Gallardo. The Law was written very poorly and in direct opposition of Michigan state law. the ticket was thrown out.

I’m a grown ass man. I don’t need an alliterated catch phrase to decide dinner daily.
