Need picture of 997 exhaust manifold


Recommended Posts

I bought a low mileage 07 C4 earlier this year from the local Porsche dealer. It is clear to me that the owner added turbo style wheels after the car was purchased. I just started doing some research for a possible exhaust system upgrade, (and I was sad to learn here that the PSE has gone up more than 33% with no change to the package). Among other things, I saw a post that mentioned a low cost header made by X51, and so I went out on the net and found a picture of the thing, and darn if it doesn't look exactly like the exhaust manifolds on my C4. I'm thinking that the previous owner may have installed X51 headers. I searched the web for a picture of the stock 997 manifold for comparison, but I could not find a picture. Can someone please post a picture of or a link to a stock exhaust manifold?

If he upgraded the wheels and the headers, I can't help wondering if he changed anything else. Thanks.

If your headers look like this they are the X -51.

The "S" Carrera has a very funky header that has a totally different configuration.

I see you have the 997 C4. It may have come stock with the X-51.

Loren (the site admisistrator) may know the answer to this.

Thanks for posting the photo. Yes, those are the headers that are on my car. I see that the X-51 package also includes mufflers from the PSE system. How would I tell if I have the PSE mufflers? (I don't have the PSE switch.) Is there a documented horsepower increase with these headers (and with the x-51 package)? The option codes on my sticker do not have any indication of an X-51 package. I know the turbo wheels were a later addition, and so I'm guessing, (do to lack of option codes), that the headers are also late additions. Thanks again.

I believe that Porsche put the X 51 headers on all Carrera's except the "S" in which they put a crappy restrictive header (go figure.) My Carrera "S" is a 2006 and I have the PSE. I do not have a switch to control it's on and off.

If you have the PSE your exhaust tips will be different sizes. Attached is a pic of my car with the PSE. You can clearly see that the outside tip is larger than the inside tip.

I you had the X51 package (which Porsche now calls a "Power Kit") you would probably see a big difference in what you paid for the car. I believe it's a $20k+ option from the factory.

If you had the power kit you would have a dual intake carbon fiber airbox. Do you have that?

I hope all my facts are correct here. I'm sure another member will correct me if they are not.

:cheers:

By the way I ordered the X 51 headers for my car :clapping:

Thanks phillipj. No I don't have a carbon fiber airbox. Darn! Great looking car!

Thanks! :D

Do you have the exhaust tips that are different size? If so then you have the PSE. Like I mentioned the 05 and later 997's with PSE did not come with a switch (like the 996.) Mine is activated when I put it in "Sport Mode" (I have the Sport Chrono option.) In regular mode I get no PSE <_<

Some folks add an interior switch in the 997 to have control over the PSE (rather than having the car dictate that sweet sound.)

No I only have the normal Carrera oval tips. I did know that PSE has the two round tips with one smaller than the other, but I didn't know if you could install PSE mufflers without installing the entire system. It looks like I just have a stock Carrera exhaust system. I'm thinking about getting the PSE system, but I see that the price went way up a couple of months back, and so my negotiations with the wife will be a bit more difficult :rolleyes: .
