Gruppe-S Jet Hot Headers onto STi

Can I run these headers on my STi and not get a CEL? Can I run this without engine management? And will I gain power? I have a Blitz NurSpec Catback....

TIA

yes
yes
yes & no

IMO you'd be better off spending your money on a downpipe at this point.

Would I lose the boxer rumble with that header?

This is what I'm thinking of installing -

PE1818 (running stock boost)
Perrin Pulley
PDE Downpipe
Blitz NurSpec Catback
Gruppe-S Jet Hot Header

Anyone know how much horsepower I'd have with all the mods?

No. I have it and it is nice. It has a nice torque gain. Pictures and info from my care is here.

I've heard that those hood lips deflect wind away from the ic scoop in a bad way... do you notice any heat soak?.

I like the whole WRX sleeper look tho.

This deflector was made for STi/WRX and does not deflect from the scoop. It runs the same with it on or off.

Thanks for the compliment and have fun out there!
