I was having a hard time deciding whether to buy Edelbrock header vs other header but they are currently discounted. Here are my choice but I know some of them are harder to get. Any opinion on where to buy for cheap?

1. Edelbrock Pro-Flow -Discounted
2. Comptech- Discounted
3. Greddy SUS
4.DC HEADERS 4-2-1

 

i like dc, and greddy but edelbrock mostly for muscle car for me.. i used to own 1991 chevy camaro rs..... but im gonna go with greddy or dc headers


hint greddy headers with same exhaust system brand as headers would be good

 

IDK why people are always hesitant to get Edelbrock headers just because they are big in the domestic aftermarket. After all, they do make the best OTS Honda IMs and nobody bats an eye at getting one of those. All those headers seem comparable, but DC does get some negative reviews.

I don't live in Cali, but is a USDM ITR mani CARB legal? If not, you can hide it under a heat shield anyways...

 

I agree. Edelbrock makes excellent products and they put a lot of R&D into making sure their products perform well.

DC 4-2-1 is always a good choice in my opinion. They don't make the most peak power compared to others headers, but they do make consistent gains throughout the powerband. DC also puts a lot of R&D into their products. Many people bash on them because they don't produce insane peak numbers, but power is truly about how you use it, not how much you can make at 8 grand.

Greddy has discontinued their header, but Comptech also makes a decent CARB-legal header.

 

Only on an ITR.

On a GSR, it is not an approved part.

Same with the JDM ITR header under the JDM heat shield.

Only reason to consider an aftermarket header instead of the ITR, is because the header length is different on some years of the GSR. Using the ITR header on those cars would either require modification of the header itself, or relocating the cat (which would require other mods as well).

My opinion on this, staying smog legal in Cali, leave it completely stock or swap to the DC Ceramic header purely for weight savings. Pushing through the stock cat, we're probably only talking about a 1 to 3 hp gain here, so not worth any real hassle over it, or spend very much money.

 

oh when did greddy discontinued? just curious

 

Get comptech if you can find one. Took me over 6months to find one, but i love it and build quality is gonna be a lot better then dc.

 

I have no choice, I have to swap out the stock jdm header for some without a o2 bung so I can pass state ref. Greddy still makes header for all type of cars. I really don't want to bother with DC Header because of the fitment and rust they tend to get. If any one know where I can get a set of the header,even dc, please advise?

 

I've seen Edelbrock headers online recently, brand new, very cheap. I'd go that route if I were you.

 

I have had all of these headers except the edlbrock. I liked the Comptech the best but the greddy was pretty comparable in quality welds, but the primarys were a little smaller. DC was junk and I have heard nothing but good things about the edlbrock. I would just go with whats in your budget.

 

I feel like everyone here say the same thing "DC have fitment problems,they rust,etc".

 

I would prefer comptech usa headers it worth the money and the 4-1 is the best clearance and it doesn’t bottom out like that dc headers and they always get smash.

 

Just recently. It was probably part of Trust co. filing Chapter 11 :/

They also discontinued their turbo kits for the EG/EJ and DC2/4. No love for the Honda anymore

I have never had a problem with any of my DC headers except once when I bottomed out a 4-1, and that was driver error. No, they're not THE greatest header by any means, but DC actually does put quite a bit of effort into producing headers that actually work. As I stated above, they don't make the most peak power and they're not pretty (so they're not as attractive as other options) but the 4-2-1's make solid, consistent numbers throughout the power band. AND they're CARB legal, that's hard to do.

But on the same note: I agree, the Edelbrock is probably the best choice if you can find one

 

Guys, sorry to break the news but the only header that most companies have available are DC Headers :-(

 

i say dc 4-1 header...carb legal and will improve your power

 

I had a DC 4-1 for about 9 years, stainless steel. Worked great, no issues, ground clearance was good. I sold this header with a SMSP high-flow cat and my Comptech exhaust a few months ago.
With this header on my car I was able to get to 182whp.

Not sure if this helps for a GSR but I also have been running a Greddy SS Header on my Del Sol for 9 years as well. Never any issues.

 

I suspect that some of the negative feelings towards the DC are just a response to its popularity.

 

LOL^

Go comptech. Its rare, but worth the hassle. I searched for months, before finding one. I got it brand new and its been great ever since.

 

I've had a DC header, works great...haven't gotten my car tuned yet

 

the edelbrock is a better piece than the DC and has a superior ceramic, it also has a carb number and is 100% cali friendly. the choice between this and DC is basically down to quality vs rice

 

Does anybody know where to find these header for a decent price?

 

I'm not sure what a decent price is, but I found this after 2 minutes on Google.

not bad, i played around on google for awhile with part numbers, wound up finding a chevy dealer that sold me a honda edelbrock header for less than any retailer i could find

 

Are there any CARB legal 2.5" headers?

 

Maybe Skunk2.
I belive people have also modified the collector on the Edelbrock to a 2.5". Not completely legal but close.
