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.
