Default Cobb Headers

Does anyone have these header/cat and actually feel a big difference? I've seen the dyno off of their site. But how noticable is the feel of the extra power, and how much is that "all in the head 'WOW'" feel?

I haven't seen Trey post here in well over a year. He is too busy and when anyone from Cobb does actually comment on something 9 times out of 10 it is Josh.

If you do a search, you will find plenty of threads on the Cobb headers. I have them and they rock. Just last we I reposted my sound clips. But I am gonna make you use your search button to find them...

Hey I have the uncoated version of these... And [Tony The Tiger voice/On]Thhhhheeeeyyy'rrreee GREAT [Tony The Tiger Voice/Off]

I've got ~3000 miles on them and received my 1st CEL at 287 miles. Used my Scan tool to reset it. Received another one 500 miles later. And my 3rd 300 miles later. At the time of the 3 CEL's I was running 87 octane. Mainly due to higher gas prices/lack of adequate funds to eat food at the time. I have since switched to 89 octane and have been CEL FREE for the past ~2000 miles.

After the initial install I only had the headers, accompanying high flow cat & my Greddy Catback exhaust. Which as most people knows is practically straight through. The 'resonator' on the exhaust is hardly adequate for this type of modification.

The resulting add on was INSTANT power gratification. MY RS pulled like its never had done before. However, the side effect of this new found power was a HORRIBLE Raspyness sound ala 'Bumble Bee tone' as it revved through the rpm band.

Solution: The addition of a 2.5" wide x 32" long resonator from my local Muffla` shop. It got rid of the raspiness completely. And very minorly [?] may have reduced a little power. However, its still a lot more than before. [prototype headers, stock cats, Greddy Exhaust]

The boxer sound is practically gone. Unless the exhaust is hot and the car is idling. then you can hear it. Some friends say it sounds Honda-ish. Others like a Ford Focus - RS/SVT.

It still pops inbetween shifts and sounds really smooth and sweet.

Now if I can only quiet down my short ram Injen so I can enjoy it even more so...[Short ram was free...]

Chris.

My experience is very similar to Chris's. Almost exactly the same actually with a few differences in some of the other mods. For instance I've run my headers for several thousand miles without a CEL most likely because I have a Scooby Sport Torque Chip. That screws with the temperature the ECU reads from the engine.

My car sounded like crap with a stromung cat back and I too added in a resonator with a slight hit in power. Car wails with my AEM short ram.

Powerwise, I've noticed that I need very little pedal effort to get the car to accelerate. I have the factory vacuum guage and at about half throttle the manifold pressure rises to near atmospheric (engine breaths easier). Well, so much jargon, just know that 3rd gears pulls a hell of a lot faster than it used to with just a cat-back and intake.

The only other issue I can think of with these headers is that I got one of the very first uncoated headers produced they came from Cobb with 1200 paint. The paint didn't hold up well and it boiled/burned off as soon as I started the car. I had a little bit of rust too where some of the paint had chipped or burned. Recently, I did some maintainance on the headers sanded and repainted with 1500 paint and now everything is as good as new. I'm guessing the newer headers will come with the higher temp paint now and this should be less an issue.

So the only real problem with the Cobb headers is sound. Is there a muffler that can give it that low rumbley sound, or will the Cobb headers make that impossible?

He posted 3 weeks ago on that ancient Cobb thread with stage III dyno #'s, that was bumped. I am pretty sure DLC contacted him and told him it was active and he came in to comment on the status of the NA Accessport. Otherwise, his very infrequent posts generally address issues or misconceptions surrounding the Accessport for the turbo'd cars. Too say Trey posts here is not really accurate. To say Trey is a member here would be more accurate. That is all I was getting at...

Yeah, my point was just that if CitySubie happened to read his posts, they might want to know he's less than objective.

What's the news on the NA Accessport, BTW?

The paint on my headers started to melt as soon as I turned the key for the 1st time... I have new brakes/rotors coming into play in the short near future and will be doing exactly what DoorKnob did. I hear Rustoleum BBQ paint works effectively...

With SoCal's 4month 'Rainy Season' coming up. I don't want them to prematurely rust away on me.... Will be complacent if they last 5 years.

Chris.
