Hey guys,
Long story short is I have taken my exhaust off to try get its measurements and work out what could be a restriction at 250rwkw.
I do not understand the results and where to go from here. The dump results confuse me and after the muffler to the cannon is an odd number.
To me the results are all over the place.
Results were acheived by either measuring the circumference and using an online calculator to get the diameter or measuring across the exhaust and just getting the exact diameter.
Cat pipes = 2.5inch (calculated by circumference)
Cat flange = 3inch (exact diameter)
Dump = 3.35inch (exact diameter)
After cat to muffler = 3.5inch (calculated by circumference)
After muffler = 3.88inch (calculated by circumference)
