stack size

We call it a baloney cut....

 

Most diesels are around 500 cubic inches. 3 inches is plenty, but most go for the "look". They only turn 1800 rpm, so flow isn't that big of a deal.

 

I don’t know what kind of trucks you’ve been driving, but a typical 15 liter diesel in a big truck is almost twice that.

 

I love the straight stack look. But I also love the flippers that go on the end of them. I dont see too many of them with those on them anymore

 

#### bro. Your company puts pickup truck diesels in the trucks? I though my c12 was small. I think it’s around 750cubic inches but requires at least 4inch at minimum. Most these guys on here are running big cubic inch around 900cubic inch and you need 5 inch of pipe

 

A 632 BB Chevy turning 8,000 rpm only needs 3, but if you think you need 5 at 1800, have fun.

 

Most all are 12L. That's around 800 cubic inches.

 

How come you drive semis with tiny 500 cubic inch motors with 3 inch pipe. What kind of gears you running and trans to get those tires moving. Old 2 stick like the old Detroit’s? Don’t retract on your statement buddy. I want answers and I want them right now. 3 inch pipe off the turbo is not gonna work on any semi truck. That is just plain silly

 

Now your googling truck engines becuase you really have no idea. No offense buddy but you were dam sure about most semis running 500 ci and run a 3 inch pipe after the turbo. All the turbos and even 12l have 5inch opening on exhaust side

 

Big difference between a 10L naturally aspirated gas engine and a 15L Diesel pushing 30+ lbs of boost down the intake manifold.
