Who here has installed headers on a MKIII? Are there any modifications needed for the install? What kind of headers are you using and where can I get them from? What other mods do you have and did you feel a difference? Thanks for the help.
i put a brospeed header on my girl's mk3 2.0.. didn't really make a difference... got a little more top end power, but that is also with a gutted cat and TT cat back... i'm sure next year it will make a big difference...
Well I am thinking of either doing a cam or a supercharger. Also when I do the header I will either knock out the cat, or get a whole high flow cat. I already have the exhaust. So would a header help then? Thanks for the help so far.
a header should be the last thing you do to squeeze that last hp out of the car.. Even with an exhaust you'll be lucky to see a 3hp gain.. IMO not worth the money. If you have money and nothing better to do than go for it. I would spend the money on form forced induction.
well I am not going forced induction. I am getting a cam, and either a high flow cat or knocking out the one that I have. So would headers help out a little now? Also what do I have to do with the air pump?
