Exhaust Problems
 

Hey Everyone. I just installed a whole headers back exhaust on my 2.2 vtec. I am at a loss. I think i missed something. It sounds good but during acceleration between the first 2 gears it is acting like i dropped too much back pressure. I need to know if they make a wire harness extension or if anyone can tell me the proper way to make an extension for the 2nd O2 sensor. I want to deal with that first to make sure its not the culprit. This is my first honda build, i am thinking i missed something. Since adding the headers do i need to do something to the let the engine recalibrate or something. If i sound lost its because i am..lol. Any help from the Honda Enthusiasts here will be appreciated. Thanks.

How big is the exhaust ? You still have a Cat in it right ?

If you went bigger than 2.25' (mandrel bent) than that is your prob.
Also the f22b1 engines are performance pointless engines. Your vtec is low end (for gas mileage) not high end vtec like b16/18 f20b/f20/f22c or h22 engines that need the bigger exhaust for the vtec power.

Also you have to understand you are running a 150hp engine on supper LOoOoOong gears made to get gas mirage not to be fast. Now if you want to put some pep in your cars step swap for a h22 trans and it will be a different ball game.
