[irondude3]

i have a pro 4 and want to know if i have to run a full exahust on it

No you dont have to run full exhaust. I just run about a foot of pipe from my header.

what kind of "STOCK" car comes with a header????

 

[ron77]

some of the older cars hads header like the 89 ford escort as one.
Some of the 88 89 cavailer have it you have to find it most ,are like finding neeld in haystack

 

[BIGDON]

I don't think anybody cares if you have a header, don't you have one?

 

[demoderbydude]

i am just kidding with him, i sold him that car. a little inside joke.

exhaust lenght is one of the most effective tuning aspects of 4cyl cars. experiment with different lengths to find what works best. i had about 4 feet on the neon when i had it. that worked the best for me

thanks for the info i have about two feet off the manafoild and did not know if that would be legal

 

[ron77]

yes u do know aara is maken everyone run one

cut the pipe long and paint it. be sure to give the paint time to dry. start the car and run it up to operating temp.
check the pipe to see where the paint stops burning off. cut it there and it will be perfect for your best performance.
