Hello folks...if you have experience with these mods please chime in...please no discussion on how O2 sensors work...:)

I have DIY CAI/K&N and Hondata reflash and an ETD. Looking at more basic engine performance mods without going too crazy. I will be staying emissions compliant. Considering the overdrive/underdrive pulleys are $200 + $75 install, and a CT header is about $500 + $0 (me) install...

Which would be the better mod to do next, considering the performance gains and price?

Thanks!

I'd say the pulleys are a better bang for your buck. You'll feel the car go quicker in 1st and 2nd gear, it's cheaper, and it (theoretically) improves MPG.

Header paired with High Flow Cat otherwise i think you'll bottle neck, is that right? If not get the pulleys and save the 75 for something else install is really really simple man,should only take like 1-2 hours tops especially if you can get another set of hands. NO AC issues here either.

i have both and i'd vote header. the pulley's are nice, but having the car breathe better is probably the more desirable benefit. adding an intake, hi-flow cat, etc... will add to that overall.

Why would you loose cooling in the a/c?
I was speaking on behalf of my personal experience, but the theory is that the Alternator underdrive pulley is causing the A/C to lose some electrical power(Sacrifice electricity for lighter weight and lower mass rotation).

Now if OP wants to use only the UR crank pulley, then I cant say if he will lose cool a/c air or not since I have not tested it myself. My guess would be he would not lose any A/C cool air if he decide not to install the Alternator Underdrive.

header hands down. see if you can jump in on that group guy.

header, along with pulleys, offer the highest hp per dollar spent. but if you had to pick one, definately the header.
