who makes the "best" one? i have heard and seen alot of DC Sports Headers and they seem to have good build quality and have a huge range of parts. i was wondering if there were any more in roughly the same price range that performance wise were as good. IIRC a 4-2-1 header is better for top end power at the sacrifice of "low" end tq

not sure about others, but I was more than satisified with my dc 4-2-1 header in my d16z6.

4-1 has been known to make power over 4-2-1 over the entire RPM range...

For the money, the DC is the best you can get. Bisimoto is currently the best header available for D series, with gains of 10-15 WHP. Of course, you pay well over $500 for that kind of header.

DC 4-1 ceramic coated! did lose a little low end tq. just judging by feel, and with cold air intake, nice greddy evo cat-back, and the header, it makes a nice little diff. in the pull from 3500-redline!

Wondering the same thing. Dont anyone say search, because I did, and theres not a whole lot of threads on it besides "Is XXXX header good?", and then everyone just says buy XXXX header, its better.

Are there any headers that are going to make moderate gains across the whole rpm range, or is it a give and take kind of deal and your either gonna gain low/mid power and lose top end, or lose low end and gain mid/high end power? What would be nice is a header that makes even gains across the whole range, or even doesnt LOSE power in the low end, but still makes power mid range and up top?

I've heard recommendations for the new DC's since they've fixed the weld/rust problem, and also the HP Racing header, but havent read up on it much.

Best buy for the money but you are not going to get much out of a d16 motor. Save for turbo.

"Best" is a very subjective term. Best on a stock motor? Best on hi compression motor? Best under $200? Best below 5000 rpm? See where I'm going with this.

I'd definitely argue this statement. I GUARRANTEE that Dave at SMSP makes a better product. I have personally worked with Dave on his first ITR application and his attention to constant improvement and detail are unmatched. Here is a thread to back that up. Take a good look at the mods to the test car.

Builthatch just used a newer "larger diameter" prototype version to put down good numbers.

Another option out there is the Rage Racing Header.

Would that SMSP header bolt right up to an EX exhaust with the cat between the header and B-pipe and not IN the header?

I'm not certain if the SMSP D-series is factory-length, but I believe it utilizes a larger-than-stock collector, so bolting it to a stock EX cat & exhaust wouldn't be ideal even if it were physically possible to do so. Those who purchase high-end headers from fabricators such as SMSP are normally looking for the best performance possible, and are therefore normally willing to modify the rest of the exhaust system to create an optimal setup.

Thats great. I wouldn't argue you, BUT i'd still like to see a TitanMotorsports-esque header test with d-series headers.

Well, the rest of the exhaust WILL be getting replaced, but can it be done so w/o moving the cat or modifying a pre-built cat-back exhaust? So that it will basically be a bolt-on affair is what I'm wondering.

Don't know if I can agree with the bisi being the best at this point. SMSP and Rage units seem to be setting the new bar

yeah right lol :thumbdown this guy is a master mind when it comes to D sers. his sohc did 10 sec all motor. there is no one else in the world who has done 10 sec out of an all motor sohc 1.5

haha my thoughts exactly..

the best header is the one that is best constructed that you can find for cheapest. for the 3-5 or whatever hp you will gain from a header, its not worth it to spend ungodly amounts of money, because for not too much more you can have a used turbo/manifold and be halfway to more hp than you will ever get in n/a form.

i heard this was a very good header

Where did I discredit Bisi or his accomplishments? What I did state was that I believed there was a header out there that was better and provided PROOF as to why I believed that. Why don't you read before you comment and keep your responses on point!

civtegra_hybrid

lol stay on the subject guy, now don't forget that were talking about D16 headers, right. not ones for a type R... that **** is way diff. so back to the point, for a D16 BISMO HEADERS ARE THE BEST in my book, just look at his track times with those, he freaking designed them him self. when it comes to SOHC you have to admit, he's the man. (just a fact)
