Okay, so I need an honest answer. I have a 2000 Honda Civic LX Sedan with a D16y7 motor and matching tranny. I want to swap the automatic tranny for a standard one. Is it possible for under 500 bucks? And another thing is getting a full exhaust, I had a guy at a performance shop tell me I cant switch out the exhaust manifold to a 4-2-1 header or what not because the engine needs to heat the cat up which is why it is close to the engine unlike the other ones. Is this true? Can I replace the stupid one piece exhaust manifold to a longer better Header so I can put on a full exhaust system. I do not want to swap the engine. Another question is I want to swap my rear drums for disc brakes what is the cost range for that and is it legal in Texas?
