As I have posted in the past few weeks I am going to be building 89-91 Civic Si HB (as soon as I find the car) for the SCCA Solo II STS class. I have started looking on Ebay and other sites to find that there are a ton of 1off headers, and intakes out there. But my question is are there any differances between these companys? Say a DC sports header and a DC style header (the welds look good on some of these pics)

I figure that the differances in the intakes are just the filters, and the headers would be the welds. If anyone has info on the differances please post.

Thanx

Hey, if you did some research you would probablly find that the difference would be the diameter of the piping, if it is mandrel bent or not, and if the inside is polished to a smooth surface to increase flow of exhaust/air.

Research? I thought I was doing that. Asking a group of people on a tech forum to make a call based on their experiances. These are basic bolt-on I'm looking at. If the size of the tube makes a differance which is the right size.

My whole thing is that a knock off maybe as good as the origional and you not have to pay for all the hype. I figure anything is better than stock so if a CAI, Header, and exhaust from say AEM, DC Sports, and HKS give you a total of 15hp and cost you $1000, and you knock off brands give you 12-13hp for $500. Is a mear 2hp-3hp worth twice the coin?

good bargain shopping Michael. save the money for something worth the horse power. It' like buying nike shoes or reeboks. if that makes any sense. later

vb, you couldnt have said it any better.. i would go to manufacturer's site and check out the measurements, then see about the knockoff, because usually you can find measurements on those too.. the differences might only be subtle but it could be the difference between a cracked header and one thats still working...

Hey, why don't you save your money on the intake and header and go buy a turbo kit for your car. Each psi is worth about 8-10 horsepower. The avg. turbo puts out 6 psi so u got 48-60 horsepower right off the bat.

Because I am building the car for a specific class I can only do bolt-ons. No boost

Man I love Ebay!!! I just got a camber kit, CAI, and strut tower brace for less than 200 shipped. Thats less than buying a DC sport tower brace and having it shipped. I am so stoked!!

nice deal bud , and a little test to make sure your getting good flow thrrough the filter... put the filter over your mouth like a mask, and breathe in, if you can breathe normally its a good filter, if not switch it to a K&N... they last forever
