RkSport and DcSports both are very well name brands, but their headers for the 2.4L look very different, the Dc one has more of a straight through design while the Rksport one has the bends towards the front, is there a reason for this? Or is it just for looks, so you can see the piping from above the engine bay...becuase I think it would look cool lol
Basically, I'm asking the different in sound and performance of these 2 headers.
DcSports -
RkSport -
I can't speak for DC as i don't own one.
But the advantage I see is that DC has a lower price and easier to install.
As for RK, which i have, it is great and I immediately notice a huge gain in the mid to high rev. A gain was gained at the lower end but it was not as big as mid/high.
One thing it left me was a rumble and throatier sound, think standard SRT-4 like.
I bought it for many reasons but one thing is for sure I don't regret it.
If you decide on the RK one go with carcustoms.net to buy it. Best deal around. And if you decide on any header,
invest in one of these. Under hood temp will be very with any header.

Nice, thanks. Not being a smartass or anything but how would the dc header being eaiser to install, they both look pretty straight forward to me.
Naaa don't worry i didn't take it as a smart ass.
Well, on the RKS, you have to rock the engine forward so it slides in, that alone took me an extra 3 hrs trying to figure to out how to do it right with out the engine going out of place or falling on me or my friend. On the DC one, it is all of a matter of removal of manifold and replacing it with the header.
After that is all done, I strongly recommend to have a friend help you and to weld it in.

are you comparing the 4-2-1 here? b/c that would really help me decide on the DC if it was just a matter of swapping. b/c if im not mistaking, you would have to rock the engine forward for a pacesetter too

Yep indeed 4-2-1 from RKS vs DC's.

Nope. None of that has happend, but i am also using the header jacket so that alone helps tremendously with the radiant heat. Besides if you are worried on that ever happening you can put this
heat shield on the firewall.

The Dc pics if right from www.dcsports.com after i typed in the make, model, and engine.
I know DC makes great headers, anyone know who actually makes RK's headers?

I know the Dc header eliminates the cat converter, and judging by the o2 sensor hole in the Rk one, I'm assuming the Rk one does too, correct?
I have the pacesetter one and it took quite abit of manuvering to get the stock header out and about the same or more to get the pacestter one in. I never heard about rocking the engine forward. How would you do that?
Do either of the DC sports or RK sport headers have the O2 sensor problems?
Just wondering but why aren't you considering the Pacesetter header?

Aren't all Pacesetter headers 4-1? I want 4-2-1.
Why?

I want to distrubute the airflow more evenly? down the lenth of the car, I had a pacesetter 4-1 on my 2.2 and i didn't like the effects of it at all...then again it was a 2.2 after all.

Well,
I don't have the pics anymore, and my old post has red x's but here's some info:
For the 2.4L
RKSport either their original 4-1 or the above piced 4-2-1
Pacesetter 4-1 everything
DC sports 4-2-1
O2 sensor placement.
RK Sport 4-1, located in the exhaust pipe runner #1
RK Sport 4-2-1, located just before te flex pipe (piced above is the ecotec 4-2-1)
Pacesetter, located after all the runners at the collector, a.k.a. like factory
DC Sports, located in exhaust pipe runner #2
Cat Convertor yes/no (box contents)
RK 4-1 or 4-2-1 bolts up before the cat
Pacesetter bolts up before the cat.
DC Sports includes a cat elemator pipe. ALSO has a weldable flange if you wanna use the cat.
So there you have it.

To my understanding it is RKS themselves that makes them.

Nope, on the RKS you can attach the stock cat--it will slip over the standard pipe.

RKS has no 02 problem. IMO it is perfectly placed.
As for rocking the engine forward, we had to dismantle all the supports/mounts and placing a jack with wood under the oil-pan for support. One person had to pull on the engine forward (or rock the engine forward) while the other person will slip the header in the back. I am sure there is another way, but this was the way we did it.

why would you want to eliminate the cat w/ the DC? how would i get it so my magnaflow cat fits up with it?
* * BIG FOR SALE POST * *
I personally would not want to eliminate the cat due to inspection reasons but that's just how the Dc header comes, but I guess you could just put the cat behind it.
with the dc sport header they supply a flange that you can have welded up to the stock cat
or you can cut the pipe they supply you and add a cat converter
the choice is yours
also if you wanted to install the header yourself to save some money or you dont trust a shop to do it , the dc with the cat eliminator pipe is 100% bolt in
so you can drive to the shop after and have them do the cat for you
rkcrappy's you get that pleasure

I beg to differ.

After header install, I got to slip on the stock cat to the header with no problem. After 4-days, I went to a exhaust shop and weld it in with a new exhaust set-up.

DC Sport was easier to put in than the stock was to take out. I love mine, and it looks good, and performs just as well
