CAN THIS BE REAL

huh, looks like they are selling the Top Speed headers like every other eBay seller. If so those are the same headers that Che(Delubozparts) sells.

From what I've heard all the headers available for the non e-gas are pretty much the same.

Um, yeah it's for real. Take a look at the completed auctions for this exact heading. Several of these headers have sold over the last couple of weeks for as low as $77!!! But you get what you pay for. Don't expect to receive anything better than really cheap headers. Still at that price you could almost just throw them away if you didn't like them!

You get what you pay for.

I hope so. I won one of these auctions last week. I have not received it yet but it should be this week. I'm scheduled for some Dyno time this Saturday. If all goes well I may be able to post some results for these headers. :dance:

I see lots of CEL problems with something like these.

Do they make these for the Dodge Charger too?
:cheers:

You should be fine as long as you keep the 2nd set of cats towards the rear muffler. I've only hear people having problems when deleting both sets. :cheers:

There's a reasonable price for everything. "You get what you pay for" is true, up to a point--beyond that you're just paying an artificial premium.

I don't believe that most of the porsche parts out there in the aftermarket are worth as much as they're selling for, but this one is definitely on the cheap side of things.

You're almost guaranteed some combination of the following:

1. Made in China, copied from some westerner's design.
2. Poor fitment (warped flanges, poor quality control, cold welds, etc.)
3. Poor long-term durability.
4. Minimal engineering work done to ensure a benefit.
5. No product support.

Most of the problems with CELs are related to the o2 sensor location. Most people put the none e-gas headers on e-gas cars....that's a no-no.

Okay, I was skeptical when I ordered these but was willing to take a $100.00 risk. I received the headers today and I have to say so far I am quite pleasantly surprised with them. I have seen several other headers that are available for the Boxster and these look equally well constructed as any of them. They are stainless, Tig welded and have a mirror-like finish. The flanges are 10mm thick with 1 5/8" tubes and a 2" collector. The inside tubes are also ported at the flange for smoother exhaust flow. I hope to have these installed and on the Dyno by the end of the week. I'll post any fitment issues and results when available.

awesome cant wait

:cheers:

I am genuinely interested in how loud they are with the top up, just the SS Dansk unit raises the interior noise a lot. I'd love the gutteral sound of headers and extra horses sometimes, however, calling attention to your car being exceptionally noisy can't be a good thing as far as avioding the pullover.

I purchased a similar "Chi-com" header for my Jeep Wrangler about 6 months ago for about $50. I haven't had any problems with it even after some off-road wheeling and could of runs on the beach. I suspect that many aftermarket products like this are made behind the "Yellow Curtan" anyway. I do have concerns about quality control. It is easy to make a weld look good even when it isn't. I'm not sure that I would do the same for a Porsche though. Just my opinion.

From seller's page:
"these will unleash the power of your boxster"
Any truth to this, do you think?

If you are really interested in the headers just ask if Top Speed makes them. If so they are the same as all the other ones on eBay......which are the same a board sponder, 'delubozparts' sells.......which are proven on the board by butt dynos and 3rd party dyno graphs.

The reason I brought up the CEL issue is the headers replace the existing cat/manifold which contains O2 sensors. I don't see how you could bypass the system (unlike the secondary cats) without disrupting the fore/aft sensors. Could someone please educate me on this?

I know this question has already been asked about other headers and I guess would be the same with these headers....

Using these (or other aftermarket) headers with the stock muffler would make the car noticably louder?

Well no one has had any problems because the bung-holes are still there for the O2 sensors on the headers. So in a way, it's just fooling the sensors into thinking the Cats are still on. As long as you keep at least 1 set from what I have heard, no cell light will come on.

The CEL's can be eliminated in my application ('02 Boxster S) with a reprogramming of the ECU. Basically, you program it has as a Euro spec. car which is only looking for a signal from the front O2 sensor (on the first cat.) and not both front and rear sensors. This set of headers only has one O2 bung which is good for my application as I don't have to add one or block of an extra one.

So do these have the bung holes in them for the 2000+ cars? If they do what do the 97-99 guys do...plug them up? I've never seen a header that claims to fit 97-2004!

The headers I received only have one O2 bung, it is located at the rear of the header near the collector.

Performed base dyno runs over the weekend. Just a little background info. on my car. It's an '02 "S" with 17k miles, manual trans. Engine is stock with the exception of an EVO airbox. Dyno runs were performed on a Dynapack 3000. Three pulls were made and peak hp only averaged 180 rwhp @ 7,200rpm. I had expected see closer to 200 rwhp, even at a 20% power train loss. Headers should be installed and on the Dyno again today.....

Your numbers seem very low for a S. Are you sure it's being dynoed correctly?


Here is a healthy S dyno chart. Stock & stock w/ evo intake set up.

I agree, the HP numbers mine generated are low. I don't know why yet. The Dyno and the techs performing the runs do a great job so right now I'm at a loss. They called a few minutes ago to inform me the headers went on this morning without issue and will be on the Dyno again after lunch. I'll post some graphs when I have them.

I'm confused :confused: . I have a 2002 S as well and I have a fore and aft O2 sensor on the pre-cats.

SRQ, why does your S only have one on each side???

[QUOTE]SRQ, why does your S only have one on each side???

My car does use four O2 sensors. With this header set I am only going to utilize two of them. Programming the ECU as an ROW car will eliminate the CEL for the missing sensors.

Picked up my car last night. Headers went on without any fitment issues, ECU was programmed for single use O2 application and Dynos were run. MY max rwhp without these headers was 182.5rwhp. and 199.6rwhp with headers for an increase of 17.1 rwhp. The engine now has a slightly more aggresive exhaust note and it passes the butt dyno test. So far I am quite pleased with these headers. The quality, construction and fitment is on par with any other aftermarket header I have seen and they did have a measurable performance gain. I'll still post some graphs when time permits.

I've been following this thread and am considering doing this. SRQ Boxster, who reprogrammed the ECU and what was the cost of installation and reprogramming? If these work out, it sounds like a win/win/win situation. More horsepower, aggressive exhaust note and two less o2 sensors to worry about replacing down the line.

The work was performed by Renn Haus here in Sarasota. Total for install and ECU programming was $300.00.

Thanks, I think I am going to take the plunge. Do you know if there any issues with reprogramming the ECU to the Euro specs? My next step is finding a place in the Chicago area that would be able to that. I'm not sure if there is a Porsche performance shop around here.

I don't want to burst your bubble but most CEL are triggered after several hundred miles have been driven.

How did they adjust the ECU to run RoW spec? Are you still able to pass emissions test this way?

CEL is not an issue after reprogramming. The RoW program is only looking for a single O2 reference signal. I believe the reprogramming of the ECU is done in its configuration but I would contact Guy at Renn Haus for specifics. As far as emissions go, we dont have state inspections in FL and at this point I am still running the secondary set of cats.

Are you sure you have an S!? Those are 2.7L #'s there.

Lol thats what i was thinking!!! post a pic of your car!!!!

My car is in fact an S. I don't know why the HP is indicating as low as they are. The car is quite healthy and I know it not actually "missing" the 45-50hp. I auto-X this car several times a year and have never finished out of the top 5. I've always giving more credit to the car as I dont dont consider my self that good of a driver. Here's a PIC from an earlier thread.

Crap, I never thought about emissions. I wonder if there would be any issues with removing the cats come inspection time?

i wish you had not installed the headers util you got the dyno mystery straightened out. With a number so low, it hard to really say that the extra power is from the headers or from a correction to whatever caused your super low initial pull numbers.

i'm very interested in the header, by the way


as far as the price is concerned, i'm not surprised. my younger brother is a welder / fabricator for a company that makes custom trailers, and he makes headers frequently for people by copying (or at least approximating) designs of high end parts. he pays little or nothing for materials, and he used the shop for free. i've seen him sell headers for prices similar to these. i'd get him to fab some for me, but i can't get my hands on a decent model to copy.

Ya, Dyno numbers surprised me more than anything. The guys at the shop ran one of their own cars prior to mine, an '02 S with a different style header than mine but it has the EVO intake, ECU tunning and a B&B muffler setup. HP was in the 210 range. I suspect it's just the type of Dyno or the way it calculates HP as my car runs super strong and has zero drivability issues. So far I love the headers and the perceived butt dyno increase.

So where does the other sensor go? Does it just stay unpluged? Does that work? Do you just cut that other one off? :confused: Seems like it should still used both O2 sensors. I ordered these headers and now I'm having second thoughts. They should utilize both sensors. Most other after market headers do. :confused:
