Seems to work for me.

 

for 300.00 dollars i wouldn't spend the money. They can easily be found used for half the price

The dc gained 4 whp and 2 ft/lbs of tq over the stock header on my car.

Does anyone know the specs of the DC Sports Header?

Primary Diameter
Secondary Diameter
Collector Size

I believe the collector size is 2.0". Just wanted to verify.

should be the third or fourth post

 

not to go off topic ... but which one would be better ... a DC with collector mod or a Weapon R with a Collector Mod... thanks ...

 

It would depend which one had the bigger primaries... Anyone can chime in with the diameters?

That's what I'm looking for, because there are some exhaust calculators out there that determine that's optimial for primaries, how long it should be, optimal diameter for secondaries, how long that should be, as well as collector size depending on engine parameters and camshafts. I want to play around with it.

 

I installed one of these at work. Not sure on exact mesurments but the DC is smaller then the stock. Just a wast of money.

 

just mod the collector to 2.5" and there you go a cheap and affordable header.

I did it to my DC header and i noticed significant gains on t he butt dyno. It definitely pulled alot harder when i modded the collector.

I will post the before and after dynos with this header.

Just get a used DC header. I got mine for $50 off a friend.

good luck

So its a waste of money because of how they looked to you?

See the 5th post for dyno proven results.

 

i have a dc sport mated to stock dp. ill sell it for 50 plus shipping

 

Buy a used DC header, hack the collector off and have someone weld up a 2.5" pipe on it.

 

you should get a greddy header in my opinion, its only a few bucks more, and it yeilds much higher gaines, also looks 10 times nicer being all SS

 

so no one really answered my question ... which is better to mod. a DC or a Weapon R ... btw weapon R on ebay is really cheap ....

 

DC used

 

I have a DC 4-2-1 ...No complaints

 

hey
i got dc headers used too
got em for like 65$

hrm, im currently
running
2.25" piping with a high flow cat

if i open up my collector to 2.5, or should i go 2.25?

thx

The weapon r made 2 whp and 2 ft lbs of tq over the stock header.

The DC made 4 whp and 2 ft lbs of tq over the stock header.

*Both run open header*

Get a used one.

I had a CC 4-2-1 on my lude and it def. helped the mid range/top end.

The only thing I didn't like about it was the oxidation after a year or two.
