Maybe. I've avoided getting an exhaust because they're really expensive in relation to the amount of gains you get. Plus, I don't want one with a tip bigger than 3", which is hard to find. And finally, they're noisy and attract cops.
But if I found a cheap, quiet, lightweight, small-tipped, gain producing exhaust I'd totally buy it
get the hks hiper exhaust. it's cheap for only $275, it's small, it has that nice jdm-angled look, and it's relatively silent except at higher rpms. i have no idea about gains, it was the first engine mod i got and i didn't feel any gains, but with intake and a header you should feel something.
Do what i did, go to www.mufflertech.com and buy the OBX rear section, i got the model II, but get whichever one you like. The tip is exactly 3 inches but looks smaller on our cars, with just the rear section its noticeable but not loud, and its deep so it doesnt sound like a bunch of bees behind you. But for about $70-150, you can go to a muffler shop and get custom 2 1/4" piping, best bet. You will feel a gain and it sounds good, its basically the same design as a cat-back just a whole lot cheaper!!
Do you have to weld a piece of metal to the header if you have an LX, or will it bolt straight up?

I have no idea. There's a DIY here somewhere for putting the HP header on an LX, but that was including the piping and everything which becomes illegal since you lose your cat. But it might help you out.
Hey Iron, if i get a HP header without the downpipe is it emissions legal? (02 manual EX)
Edit: From what i've heard on the site, the DC header sux...the HP would be nice to add cause i have a CAI and a cat-back...im hoping its legal, at least the top portion...

As has been stated in this thread before, if you get just the top portion it will not replace your cat (on an EX) and therefore should be legal. I don't think anyone is quite sure, however. Someone posted once about a guy who had just the top portion and passed emissions, so it should be all good.
As far as I know, as long as it doesn't replace your cat, it's all good.
wheres the best/cheapest place to buy one new? it seems no one sells these used, at least the shorty with downpipe. i dont care for turbo, i want to build a all motor beast.
it doesnt just matter if they can pass emissions, it matters if it is cvarb legal for Ca at least to pass visual inspection, i mean a turbo should passions emissions but that doesnt mean it would be legal
