Dyno after ebay headers?

[rcfanatic]

Does anybody have dyno results before/after installing ebay headers on either a b25 or b27? Couldn't find any info in the previous ebay threads.

Wondering what kind of difference these make on a stock tune

those interested in cheap ebay headers are probably not the people who would be forking out extra to go to the dyno

A bunch of the PRO3 guys run ebay headers I hear. They might dyno their car :)

my car has ebay headers, other mods too.
gonna dyno it before i do my turbo and after my turbo so i can see what i actually gain.

that doesn't make any sense. that'll tell you what the turbo gained, but not the headers.

I agree with digger - the headers cost around $100-150. an hour of dyno time is around $150, and most shops charge another $50-75 just to put it on the machine.

plus, you really need tuning to take advantage of them. The pro3 guys can tune for it (they're allowed piggybacks). 99.9999999% of the rest of people using them aren't going to do that, you'll spend 10x as much on tuning and dyno time than you did on the headers.
