headers and powerband

Post by **Dattebayo** » Sat Dec 21, 2002 10:52 am

i have a pretty extensive n/a design and ive been looking for a decent setup for headers that will clean up the mid powerband. I dont want to spend a sh*tload either so help me out.

hotshot headers are the best .

Post by **Dattebayo** » Sat Dec 21, 2002 10:52 am

really? that surprises me. what exactly do they have as a feature that stands out from the rest?

Post by **perpetual gyro** » Sat Dec 21, 2002 10:52 am

Yeah I've heard some not-so-good things about them, so i'll give this a bump.

KA headers are rare. Greddy sucks *** and they break all the time. S&S are cheaply made I think there is another company that makes headers too but they suck! Hot shot makes the best header for the KA I like mine. It makes loads of lower end torque!

I like the collector on the Hotshot and the fact the the header is 7 feet long...

that other brand that makes crappy headers are pace setter I believe.

Post by **I am Technoman** » Sat Dec 21, 2002 10:52 am

yes think you, Pace setter is the real crappy one...can you say rust into!

Post by **I am Technoman** » Sat Dec 21, 2002 10:52 am

Im sure greddy has remade the 4 into 1 header. I had 3 of them and they all broke To thin at the collector .....

It seems like out of the options you have, people like the Hotshot headers the most. From what I hear, they produce the best powerband. But I also read from the tech page that they tend to rust easily and there were some problems with the allignment or something in the installation. I think they may have since fixed these problems, but i'm not sure.

anyone know what site has the hotshot header the cheapest? thanks

Post by **nnkfws333** » Sat Dec 21, 2002 10:52 am

I think enjukuracing.com has the cheapest price with $329 with free shipping.

At one time the hs header was a 2 pice header "tri y" HS has scince changed it to a one pice 7 feet long fire breathing header. My hs header starts at the front of the head and dosnt stop till under my drivers seat. NO CAT The thermo coating hs uses seems to be holding up nicely... and did i metion the sound ! it unreal with a Borla muffler!!!

technoman

for obdII cars then, if you have to get rid of the cat, will the ecu throw a code then?

Post by **I am Technoman** » Sat Dec 21, 2002 10:52 am

Yes it will through a 420 code HA HA I said 420..

It will not affect performance…

Can the stock heat sheild be used with these headers?

Post by **perpetual gyro** » Sat Dec 21, 2002 10:52 am

i see people not even using heatshields, so.......

actually, come to think of it, if i had Greddy headers (known to crack, which is due to extreme tempurature changes), i'd probably leave the heatshield off of it cause then the heat would be distributed throughout the engine bay instead of contained in the immediate vicinity of the headers. Just make sure you ventilate it well.

Post by **Dattebayo** » Sat Dec 21, 2002 10:52 am

oh well i got the greddys for christmas... maybe i should exchange them... i do have a receipt but these look a little different than the ones i see around. maybe they did change them.

Post by **perpetual gyro** » Sat Dec 21, 2002 10:52 am

maybe....let us know when/if yours cracks.

Post by **doctorj240** » Sat Dec 21, 2002 10:52 am

a heat shield will actually help performance by keeping the heat inside the header. hot gases will exit through the header faster than cooler gases. you'll get similar results by using heat wrap on each of the runners all the way to the cat. it'll keep your underhood temps a little lower too which is a good thing. you don't want to melt stuff.

Post by **nnkfws333** » Sat Dec 21, 2002 10:52 am

I believe that is a good answer above me but a lot of people get rid of there heatshield also is cause it rattles sometimes. I know mine did and I took it out and no more rattle

I want to get hotshot headers if I decide to go all motor, and I probably will. Can I install a high flow cat? I want to get N1 dual exhuast, will everything fit well, will noise be legal, emmisions, and what's this about codes and the ECU? What's a 420 (haha) code? That isn't going to set off my check engine light, will it?

As for emissions, well, no cat=no pass.

Post by **apzak** » Sat Dec 21, 2002 10:52 am

high-flow cats should pass, right? What exhaust would you suggest? I'm intrested in performance more than sound, would like to be legal, and something that will last, and not hit the street everytime theres a bump.

EDIT: Whoops forgot to mention I don't think I'll go turbo so I'll need the best exhuast for NA

Post by **perpetual gyro** » Sat Dec 21, 2002 10:52 am

yes, High-flow cats should pass, but i don't think you would have room for a cat with the HS headers and a cat-back unless you hack the pipes somewhere..i could be wrong though.

also, the best exhaust for NA would not be the Apexi N1....theirs has a 3" diameter...NA exhausts should be 2.5" in my opinion. The Apexi N1 exhaust will rob you of some power due to the uneccessary large diamter for NA..

Post by **I am Technoman** » Sat Dec 21, 2002 10:52 am

a 420 CODE IS UNIVERSAL obd 2 FOR A BAD CAT IN YOUR CASE NO CAT. it WILL TURN ON THE LIGHT BUT THERE WILL BE NO PROBLEM..

If you want to fix the problem get an auto secendary cat extend the rear o2 sensoir past that to fool the ECU.

SORRY CAPS BUTTON LOCKED

I heard wrapping thermowrap around the already ceramic coated hotshot header will MELT the thing due to excessive buildup.

The hotshot header is already ceramic coated, and the engine bay temp isn't any hotter than with the stock manifold/heatshield. I was going to wrap it up with thermotec wrap, but after reading that post about melting the header, I thought about it and it makes some sense.

As for the guy who's car rattles in 4th gear at 30mph under heavy acceleration, that doesn't seem like heat shield rattle. My heat shield rattle when my engine was at high rpm's at full throttle. Your rattling sounds like it's something else.

Post by **Dattebayo** » Sat Dec 21, 2002 10:52 am

melting depends on what alloys the headers are made of. I have a friend with a turbo chevy and hes got wrap around his ceramic coated headers...no melting since i talked to him last

What the? 30mph in 4th gear? Heavy acceleration? Can you even be in 4th at 30 and accelerate? lol.

Nick.

Post by **Syntax360** » Sat Dec 21, 2002 10:52 am

i was thinkin the same thing - when i first test drove my 240 (coming from a slow 1.8L N/A DSM) it was a terrible ride because i kept trying to use 5th in a 30/40mph zones....there's pratically *no* acceleration @ rpms that low

Go with hot shot, just put them in my car and they look, sound and perform as expected. try http://www.enjukuracing .com they are running a free shipping special and If you live out of state you are sales tax exempt. Later
