Made the initial mistake of buying a set of OBX stainless headers, they are crap. Anyway stuck with them on the other side of the world I set about cleaning them up internally and port matching them etc. A lot of work! After install with standard cat back WOW!! Torque increase is substantial, no VTEC kick at all which is strange (can someone explain?) power from idle to redline is flat, smooth and definitely increased (no dyno figures yet). Miss the VTEC kick, like the extra power, has anyone else experienced this with headers?
