I have a civic si 09, and I want to buy headers and exhaust! I want to know which one is better, megan racing o skunk2? cause the difference is huge $$$$, and I'm wondering if any of you have had any of them?

Also I need to know if skunk2 headers has the original holes for O2 sensors, or if it not where can I buy hte 02 sensors?

Sorry for my english am not a native speacker

 

I'd go with skunk2 over megan and if you don't have hondata flashpro yet, i get that before the header.

 

But if I buy the flashpro before the headers, that means that I've to reprogram the flashpro again after I bought headers isn't it?

 

Yeah, and the flashpro comes with several different base maps for different part combos. It take like 90sec to upload a map to the ecu......

 

thanks I didn't know that!!! And do you know if I can configure a map for a street driving and a map for a race track and change it easily?

 

Yeah it can be changed easily, but on a n/a car with bolt on you will really only need one good tune. Also with the hondata you can just turn off and remove the second O2 sensor.

 

excellent! I'll buy it for sure

 

Skunk2 all the way!

 

skunk2 and most the other brands are made in same place so yeah. I used the Invidia header and made great gains.

 

Megan headers it's the best Price/quality, but for european civic we must do an adaptation after that It works fine With a powerful great song

 

skunk2! it give it a more deeper tone

 

wat

 

Bump tttttttttttttttttt
