How can u pass emissions with racing headers? no cat.
u can’t.
your #'s will be through the roof dont even try without a cat.
if your headers are short, put the cat as close as possible to the engine, some even put a piping reducer INSIDE to cause more back pressure in the cat…this will help…unfortunatelly maybe not enough
Why would you have “Racing” Headers on a street car?
thats a good question. the thing is that the only header kit that i was able to find around here is the DC Sports one. i wanted to go for the H.S first but no idea where could i find it. and the other option is Nismo which are waaaaaay over priced… so i dont know. any ideas?
you bribe the mechanic. or buy car that don’t need emission.
