B20BVTEC header
Anyone know what is the ideal 4-2-1 header for B16 head with B20b block engine. I'm thinking to get the maximum power around 7000-7500rpms. I mean does anyone know what is the diameter of pipe I should use for the header and then also the diameter pipe for exhaust? My engine is pretty much stock and I'll stay N/A in the future. Thanks.

Also, you have to take into consideration the cat location. 94-99 GSR exhaust manifolds don't have the O2 sensor in them, but the 00-01 GSR and 94-01 LS do. The exhaust manifolds with the O2 sensors in them have a longer collector to compensate for the cat being farther back.
