DC SS HEADERS Bought some questions??

[S50 NYC]

Keep your cats, not worth the $$ for test pipes and possible check engine lamp even with a "defouler"

Now I have just DC SS HEADERS I did not add intake and exhaust system the same time to see difference but honestly it is just nothing low rpms more slow and high rpms a little bit fast or the same I am not that sure and about the sound it is slightly louder in high rpms
And generally JUST putting headers is not adding noticable gains, differences to the car...

Akanay.. Just saw the first post.. In short: Catlere dokunma, ciddi bozar arabanin sesini.
