This.
They say backpressure isn't nearly as important as exhaust scavenging but for under $300, you can have a nice exhaust from exhaust ports all the way to the tip if you dont go the ebay/brand name route other than the header and maybe a muffler if you're into that sort of thing but cheap mufflers sound like shit after the horrible packing burns out of them. Just keep that in mind. S14 shorty header bolts right to an sr downpipe. I'd like to try out that, to my sr3" dp, rebuild my 2.5" midsection (it's seen better days. The low car life flattened it out in some spots) and install the ugly pipes i built:
We dont have emissions and fuck cops. Aspec pipes? $100. My pipes? $15. Flux cored ninja.
I dont recommend it but hey, it looks cool imo....
FYI, the thicker the piping, the deeper the tone. DIY/custom/muffler shop exhausts all the way. All the money you save you can spend on some header/exhaust wrap. THat will not only help keep the heat where it needs to be but keep the tone low as well. Hey, you said "stock ka". Fuck it. If you had any idea how hard it is to make power squeeze on one of those without the gas, bc stroker kit, turbo or some very serious money, you wouldn't care about 2-5hp.
