What size of exhaust pipe do I need?
What Size Exhaust Pipe Should I Use? The quick and easy way to choose what diameter pipe you will need from the headers to the mufflers is to go back to the old rule of thumb, that for every 100 horsepower, 1 inch of total pipe diameter is needed across the system.

What size exhaust pipe is on a 2007 Scion tC?

Is 4 inch exhaust too big?
This means that an extremely large exhaust pipe will actually cause SLOWER exhaust flow, and decreased performance. The general rule of thumb for exhaust systems is, as we said 3-3.5in for 250-350whp, above that 4″ exhaust is the right size, but that’s about as big as you want to go, even at the 400whp-500whp level.
Are bigger exhaust pipes louder?
If you are too lazy for the details, bigger exhaust pipes do make the exhaust louder – but only by a little. Exhaust pipes are made bigger to allow better exhaust flow. Instead, aftermarket exhaust also equips a less restrictive muffler – which is responsible for the much louder sound.
What size exhaust is on a Prius?

Is 2.5 or 3 inch exhaust better?
yes 3″ probably better, but might be hard to run all the way to the back next to the tank, if your using the smaller TTi headers i don’t think the 3″ would give much more HP, you could also go 3″ to the muffler and 2.5″ out the back.
How big is an exhaust pipe in feet?
Exhaust Pipe Size Estimate: A good section of straight pipe will flow about 115 CFM per square inch of area. Here’s a quick table that shows how many CFM each common pipe size will flow, as well as the estimated max horsepower for each pipe size:
Which is better a larger exhaust pipe or a smaller exhaust pipe?
The greater the exhaust volume, the greater the optimal exhaust size. Exhaust volume increases with engine rpm and fuel delivery. So ideally you’d have a variable sized exhaust pipe that increases in size as rpm and fuel injection quantity increases. For a fixed exhaust pipe size then you need to pick a compromise.
Why is the exhaust pipe bigger than the rev range?
Chips dump more fuel in the engine to get more power. This translates to an increase in exhaust volume across the entire rev range. The optimal exhaust size will be larger than the optimal size for less exhaust volume.
How to calculate the volume of exhaust pipe?
Easy Way To Estimate: Your intake system needs to flow 1.5 CFM per engine horsepower, and your exhaust system needs to flow 2.2 CFM per engine horsepower. Good Way To Estimate: Take engine RPM x engine displacement, then divide by two. This is the intake volume.
