do headers add that much hp.....if so whats a good brand....also need to know of a good intake not for hp more for a deeper sound whithout adding exhaust....done that to all my imports and im tired of it.
oh yeah the max hp you would see out of a header is maybe 3/4, with like 2 ftlb of torque.. and that would from a RMF header, or something equal to that. very expensive though
i can not give u proof, just my word. Sport Compact Car did a test on all major brands of headers and the one at the top was the DC sport ceramic 4-1 header, which added 5hp MAX at the very top of the powerband on the dyno. RMF headers are much better than DC Sport so it only makes sense that they would give at least 3-4hp. i posted less because i figured the numbers were slightly off. correct me if im wrong, but i have throughly read my stuff and i would not have posted it up if it wasnt true.
INstalling an aftermarket header may not add a lot of HP, but if you still have the stock cat, resonator and muffler, the increased exhaust flow is slowed before it exits your muffler. So if you install a header, high flow cat and high flow muffler or cat back system, you will get better power gains vs just installing header. Think of it as upgrading your exhuast system. Header is just one piece of the system.
Talk to 98vtec. Ask him how much of a difference headers can make. If a header is built just right so the its savaging is at its max, 10hp is quite possible. 15+ with tuning. you just need the right set of headers.
The DC sports ones are nice, but are basically twins with the stock header other than some minor adjustments to size and the collector.
Try SMSP or SixSigma. They have some headers that actually make the power worth the money.
As for an intake. Go to ebay, get a normal Short Ram or Cold Air intake for 30 bucks. Buy a BPI Flowstack and get the exact same results as the V2, but for half the price.

Go check the performance library here and look at some dynos using good header/cat/exhaust setups. You'll see from Vibrant,RMF,SMSP,MUGEN,etc a lot more gains than 3-4 hp.
The DC header is crap and will get you a HP or two, maybe. This is probably be due to errors on the dyno. ala If you do 3 pulls they will all not net the exact same result. Your better off spending money elsewhere.
with type-s cams i went from 156 to 165 whp added a mugen header and i was at 176
on a stock h22a4
now...my other motor mugen had me pushing 217...added my DTR/SSR and saw the jump 228.
ps...dont believe everything you read/see in magazines....coming from someone who KNOWS how that works.
interesting, i put down 173 whp on a stock jdm block with a POS h23 tranny, banged up dp, stock intake box with k&n drop filter, and rsr exhaust. just advanced the timing to 20.
^^ with a jdm block i would hope that you put down more than a usdm. plus advanced timing...thats a decent number....if things were so banged up you shoulda saw around 185.
Are you suggesting DC SPorts put some under the table $$$ for that article? PLease expand on that comment dvsracergirl? This is intersting.
im not saying anyone paid anyone else but i can say that more than a few of magazines arent 100% honest in what they print. anyone whose had their car in a magazine knows that the article that gets printed isnt the one they submitted!

well i got the m2b4 that will go on in once i get the clutch/fly, new exhaust and header, crower stage 2 cams with corrected idle lobes, and other goodies, i should be reachin 210 or more in a few months, i just gotta stop being lazy...
what about these stainless ebay headers that are like $70? Honestly my exhaust is just rotted and Ive priced an entire header back stainless exhaust for like $210 lol. Comes with a free intake too haha. The cat back is a knock off N-1. Has anyone here used them? Seems almost too cheap to be true, Im wondering what can possibly be so bad about it. I really dont care about making the most power possible but it cant be worse then stock right?

well if you wanna wait a bit, i will be takin out my rsr exhaust when i do my tranny swap. also those ebay header seem to make good power, my friend just switched from the camp1320 to those since the camp1320 broke on him, he didnt lose much power and his graph seems better, no dips or anything. with the camp 1320 he was makin like 3-5 more whp but he had dips.
i will be purchasing those ebay header as well.
How much would you want for the rsr? When are you taking it off? I was able to patch my exhaust a little bit with weld so it doesnt sound like a chainsaw driving down the road but its on borrowed time lol

most ppl here would recommend going with vibrant, mugen, custom (rmf, smsp, etc), FGK, greddy. these will run u 300+. looking for used parts is always nice. most ppl w/ goals of more than bolt ons definately benefit from higher end parts...but if that's not you & want to get more in-expensive parts/need to replace rotted exhuast and then i guess ebay is ok.
w/ intake, i dont think it matters much. personally i would never spend $$$ on something like an aem v2. I bought a type s intake for ~$130 and regret it. I haven't installed it and will likely sell it & keep my cheap short ram. an additional consideration is cold air intake & amount of rain/flooding u get in your area due to risk of sucking water into your motor.
