Just some miscellaneous questions about different stuff...
All the places I look at, they sell headers according to the type of car. But if I get headers for a crx and then swap in a b16a1 (for example), are new headers needed? Are headers needed according to car type or engine type?
What is the average price for installation on a b16a1 into a crx (installation only)?
Does a custom catback and muffler make much of a difference with stock headers?
whats double-clutching?
what exactly does a fuel managment system do (other than screw with air/fuel mixtures)? Can it do much for performance?
Does the ls engine (b18b1 I believe) cost more or less than a b16a1?
Does anyone who lowered their car have problems with snow, bottoming out or hitting shit?
What are the differences between the 4-2-1 headers and 4-1 headers as far as performance goes? Is there a difference?
I am not to knowledgeable about this stuff, so answers to these questions would be much appriciated.

yes you need different headers for changing from a d series engine to a b series engine.
double clutching would probably be easy to find a defenition for but im too lazy. at first i thought it was pressing down the clutch and putting the car in neutral and then releasing the clutch and then pressing hte clutch in again and putting it in a new gear, but the fast and the furious made me think otherwise...
of coarse you are going to have problems with bottoming out and snow etc if your car is lowered more than normal (common sence) i even have problems with the stock height of my rex.
(but i will be lowering it anyway)
sorry, thats all i can offer as advice from my knowledge, and some of these questions i would like to know myself.

Headers are relative to the engine, not the car.
Catbacks don't do a whole lot regardless. You can have the stock exhaust manifold and make like 3 more hp or have a header and make 5 more hp from the catback only, this does not include the hp gains from the header itself.
The difference between the 4-1 and 4-2-1 is the torque band. I'm not going to go into which one is "better" cause everyone says something different. I will tell you I have a 4-1. Oh yeah and if you don't know what the actual physical difference is, the runners on a 4-1 go from the 4 exhaust ports to 1 collecting tube. The 4-2-1 go from cylinders 1 and 4 into one tube and from cylinders 2 and 3 into another one, then those two tubes merge into one.
Double clutching is what Phiber Optic described
I fuel managment system can give you hp. It's especially helpful for turbos, SCs, NOS, and VTEC if you don't have a VTEC controller or a VTEC ECU. They are like an add on computer for your car. They add the right ammount of fuel (or air) into the mix at certain rpm levels.
I also hit things with my car which is lowered 1.8". It's just a neccisary evil of lowering cars. My downpipe and muffler take most of the abuse. It's not so bad that I can't drive it around where I live. I did have quite a few problems in DFW though.

So what is the purpose of double clutching? Is it good/bad? I dunno if i'm blind to something, but I don't really see why.

Theoretically, it's faster and better on your tranny. Try this little trick. While you're driving around town, slowly, shift like you normally do but try and do it really fast. Now, try it again but when you press the clutch in, put the shifter in nuetral. Now, left off on the clutch and press it in again to go into your next gear. See how much smoother that was?!? It's especially helpful when downshifting when your car doesn't want to go into that lower gear. The the trick is trying to learn to double clutch really fast!

i used to not double clutch... but i bought this great book by bob bondurant (i think that's how you spell his name) and it gives you a wonderful ammount of info on how to drive fast. he explains how you double clutch, saying that most professional drivers can double clutch and shift faster than most drivers can shift regularly, even when they're shifting as fast as they can. when i don't double clutch my tranny will quite litterally grind in 3-5th because i have a seriously short shifter... but if i double clutch she shifts very smooth... what old bobby boy reccomends is that you try to double clutch shift slowly at first and then when you're trying to do a quick run you progressively try double clutching faster and faster until that's all you do when you shift... peace...
