Intake + Exhaust = what hp gains overall?

chrischhorn

stillen headers are garbage. basically just a shiny version of oem headers. Nismo or Nismo S-Tune exhaust? either way for a little more better could be had. If you arent doing the headers yourself, i would a) spend the money on a FI or PPE longtubes or momentum short headers or b) get test pipes and call it a day unless you have money to spend. Header install is probably 6-10 hours of install time depending on who does it so factor in about $100/hr of labor and it hurts. took me about 7 hours to install myself.
