header with stoch exhaust!!!!
I'm just looking to improve power without making noise and am considering installing header.I've just ordered a j's intake however I don't want to change the exhaust as I don't want noise. Have you guys just installed headers to your stock exhaust and if so which ones did you use and did they help? my car is an ek4 (b16a2)... thanks

Re: header with stoch exhaust!!!!
I went from a stock D15B7 exhaust manifold to the EX (4-1 to 4-2-1 and a lot more gradual at that) and it felt a little better on the top end but the biggest difference is more mid range. Then I dropped a D15B in with a AirMass header and it revved really freely, kinda like a B series, but it had other mods, so I can't say it was just the header.
