Rep Power: 304 Just for clarification the HP H26 header with "High Flow Cat" is not a cat at all. It is just a nice looking resonator. That way when the local police look under your car to see if you have a cat, it appears that you are legal. When in actuallity you are far from it. I have the H26 with the long sweaping down tubes and the high flow cat look a like pipe. A BORLA boomer muffler and a custom made 2 1/2" piping. It is a little loud for some but I like it.

Rep Power: 223 obviously the megan headers are going to be alot louder right? I have a LX so I'm thinking of getting DC sports header and put that on a random technology high flow cat and weld it to my cat-back magnaflow exhaust. I know it will all work and ive talked to a shop that will do it a long time ago. So for me, its either DC sports or Megan..but I sure dont want it being LOUD,

Rep Power: 223 im thinking im going to get dc sport header because i want just a little more hp out of my car...but not if its going to be loud lol. Im trying to keep the noise to a minimum but still get better acceleration.
Im thinking: (EX) DC sport header
Random Tech. High flow cat for EX (direct bolt-on)
Ingalls "Stiffy" engine torque damper
Apexi SAFC-2
AEM cam gear? maybe not the cam gear idk
Kinda tempted to do a EX head swap, but i wouldnt have enough money for stage 2 cams/springs/retainers. So idk.
Do you guys think it would be better to do my first set-up kit^ above^
-OR- do a EX head swap and stage 1 cams + VAFC2???

Rep Power: 0 Well I know its just saying what's been said before, but someone needs to pony up the DC Sports header measurements so we can have a good comparison. I'm starting to like HP more and more, but megan has them beat on price.

Rep Power: 223 ya, but the HP header is longer or w/e. So its more header lol the Megan header is just that one part that connects to stock downpipe. HP you need the highflow cat piece, correct me if im wrong but i think thats right..

Rep Power: 223 wait so ur saying that the -"HP Racing Header 4-1"- is the shorty header??
If so, does any1 here have just the shorty??>
Is the HP shorty better than the DC sports?>
Is the 5.25 or w/e size pipe of the HP for the shorty or H26?

Rep Power: 287 Some people are going to disagree with me on this, and thats fine.
The HP shorty header allows you to re-use your factory cat and remainder of exhaust system. Also known as the 4-1. Looks like this:
Now, if you go with their "race" header setup, you get the header with the longer tubes and the high flow cat, which isnt really a cat at all. Looks like this:
You can see the header and "cat" in that pic.
Now, HP is the same quality as the Megan stuff. Its the same deal with megan, you can get their shorty header:
Or you can get the shorty header with their test pipe:
Now, which ever one you choose....be careful. Neither Megan nor HP properly heat treat the bungs where the o2 sensors go, and majority of the time, youll find you end up ruining a sensor or 2. Anyone who has had this problem know exactly what Im talking about.
Whichever you should choose, if you go with a full length header and high flow cat, expect lots of noise, and nasty smells. Thats just the way it goes with them. ANY shorty header you choose, is not going to sound any louder than stock. Headers dont make much of a sound difference. Its mostly in your muffler / resonator.
As far as DC goes, just because they are about the same size as stock does not mean they arent a good header. DC spends alot of time in R&D on their product and there is a reason why they are a much bigger name than Megan or HP. That, and the fact that they are 50 state legal.
As far as performance increases, you will feel a SLIGHT increase over stock. The differences between the brands however, you will never notice. Obviously going with a full length header, you will feel a bigger difference than just going with a shorty header. Either way, dont expect any noticeable gains. They just allow better airflow and allow the car to run smoother, all the gains you "feel" are mostly in your head. I say that because I have had every header discussed in this thread, and none of them gave a big enough performance increase to hoot and hollar about. Anyways, hope this helps you out in your decision.

Rep Power: 256 If you live in Cali you won't pass emissions bc it's not C.A.R.B exempt except DC. If you have an EX the cat is under the car so you will still pass smog with just the shorty header.

Rep Power: 287 Just make sure if you want to stay legal it has a C.A.R.B number on the product and alot of times it comes with a certificate too.
When i had my HP "race" headers, I got pulled over and when the cop looked at my headers, he was like "thats not legal". So, of course, I played dumb and said I didnt know. Luckily for me and a stupid cop, on the HP header, their logo is tack welded on one of the tube down a little ways, and that cop couldnt read what it said and he thought it was the CARB number. haha. I got lucky.

Rep Power: 0 The only reason DC is C.A.R.B. legal is because it's just a nicer looking stock header. Nothing else too it...just remove the heat shield and paint your stock header...slap a DC logo on it and there you go...home made DC HEADER. HAHAHA

Rep Power: 287 I dont suggest any of them. Its up to you. If you want to stay legal, go DC, if you dont care, then it doesnt matter. Either way they are all a waste of money IMO. lol. Im just running the stock one now.
#112
I really dont care if its legel or NOT, I just wanna be able to pass emissions and thats it. I think a eBay header should be fine.

Rep Power: 223 thanks for the advice spoonEM, I was already thinking if i get headers i would do dc sport 4-1 and random tech. high-flow cat..but was considering the megan header because of this post lol
I would have already had headers on my car, but decided not too because installation fee. DC sport header+highflow cat+ welding onto exhaust : /
kinda alot for a few horses, but idk i might still do it

Rep Power: 287 Well, if you go with a high flow cat, you wont pass smog. So , your best bet would be to get all new piping done from your axleback up to the cat, that way, when you have to go get smogged again, you can unbolt your exhaust and re-nstall the stock pieces. Altho, I just realized your not in CA, so Im not sure on your smog laws out there. I hate CA emissions. :thumbsdown:

Rep Power: 230 So I gave in and bought the Megan Racing header instead of the Kamikaze one I wanted to originally. I'll let you know how the car responds to two more whp haha. Also whether it sounds super cool or not through a stock exhaust.
