Kevra,

Yeah I don't understand, 4 hours, that is just unacceptable!

I just installed mine myself and the quality is great, definitely lighter than the stock exhaust. If you are expecting a major change in the sound, you will be disappointed. While it is louder, it is still very subdued which isn't a bad thing, just depends what you are wanting. Personally I would still like a little more rumble, maybe after I add some headers.

The butt dyno did detect an increase in hp but that also could be psychosomatic. All in all you will be pleased with your purchase even if the customer service is lacking ;) jk

i have a question. with the mid pipe and headers
which one set of cat are eliminated. does the CEL turn on?

On all 2000+ boxsters the pre-cats or warm up cats right by the motor are eliminated with all aftermarket headers except Fabspeeds which are a header with high flow cats.

Che, you need to bring a Fabspeed header knockoff to market and sell it for half the price. You'd probably sell a ton if you can make something like these. As you probably know, all the bungs in the world won't prevent a CEL from happening unless you have some cats.

Che,

4 o2 sensor bungs??????

He doesn't mention if the 4 bung headers will cause a CEL or not. My guess is they will. I guess we'll see once somebody tries them.

so those 4 bung are for the o2 sensors then huh?

if i was to remove the 2ndary cat close to the muffler...
will CEL turn on/?

Yeah, it probably will. In layman terms the sensors that were aft of the cats will sense too much pollution and think your cats are not functioning properly so there's a good chance it will trip a CEL light.

Where's Che?
 

Che has totally disappeared from this site. I guess business is good.

That's too bad because like many others on this site I am interested in his headers but not without having the questions posted on this thread answered first regarding the CEL's

hes around, Hes still a site sponser... His Ad is the one that says DelubozParts

No, he's been on here. he just hasn't posted a repsonse here. I clicked on his profile and it said he was actually here today @ Last Activity: Today 09:19. My guess is that he doesn't have reasonable solution to the CEL issue so he hasn't posted a repsonse. :rolleyes:

so a better solution is probably to keep the cat by the muffler...
and remove the first cat along with the headers?

would that be better?

Here's the deal. If you want to avoid a CEL then you need to keep your stock manifolds or pay $2,300 for the Fabspeed headers I listed a pic of. The other main cats down stream by the muffler can be removed because there are no 02 sensors by them. Essentially the computer doesn't know if those cats are there or not. Here's a pic of the stock Porsche manifold that che's headers replace and all the others on ebay like his. If you replace this manifold with one without a cat then a CEL is likely. This is why companies like B&B don't make headers for 2000-04 boxsters. They know it will cause issues. The 2.5L guys however are in the clear and don't have to worry about all this stuff.

oh i see!! thanks for the explaination. so the secondary cat ( by the muffler ) is save to remove and replace with test pipe... but there have to have a cat by the exhaust manifolds... i see...

Steve... Im going to hit you! ;)

You cant remove any of your cats without getting a CEL... You can remove the secondary cats IF and ONLY IF you have ROW settings flashed into your ECU or have revo flash your ECU to ignore the input from the last sets of o2 sensors.

If you look at the image, the cat on the right side has an O2 sensor screw in behind it so its expecting cleaner exhaust.

This is where the o2's are bolted to my exhaust on my 2.5.

That diagram has me scratchng my head! It shows 8 02 sensors!! That diagram is screwed up! You should be able to replace those cats no prob.

That image is from the porsche parts cataloge, its just showing all the possible locations an o2 sensor CAN go.

Yeah, I see it's trying to show both the old 2.5L system and the later system together. Confusing!!

Nah, heres the image of the 2.5 liter engine exhaust system from the cataloge.

I think this means i still get to slap Steve upside his medulla oblongata! ;)

lol.....yeah, I see what you mean now. Thanks for the info man.

i have a 2.7
:D

:eek: dont hit me
:D

but im only removing the secondary cat
Adam said it should be fine...
as long my main cat is on...

is that true or no?
im confused...

answer with yes or no!!!
make my life easier :D

Yes you can with no problem. CJ has a 2.5L so he is mixing in some of his info with mine and confusing the issue a bit. See if he deleted his cats he would piss off his computer and cause a CEL. I believe that was what he was referring to. Jmatta has the cat delete pipes. If you want just PM him and he'll tell you what I've been saying all along.

Wow, its been longtime since I check back in. Suprised this Link is still up and running LOL.

Stop in and say Hello to my old customers and friends :cheers:

Hey Che, Any plans on offering secondary catalyst bypass pipes for the later cars that have two converters on each side? Im sure you could make a nice product and still undercut the other options by alot! Thanks

I have an '02 2.7 with the secondary cats removed. There is NO cel light and it passes emissions without a problem. I surmise a slight performance increase because of the weight savings rather than freer flowing exhaust. Also it traps less heat in the exhaust system. Two little furnaces rather than four. Just my opinion.

I'm always have new products under production, I will check into these Secondary Bypass Pipes for the Boxster. Thank you !

Che

all we want is mandrel bent, stainless steel bypass pipes, at Honda prices.

AND give 150 ft lbs more torque,10 more mpg,legal in 49 states [who cares about cali] wont pop a CEL and install in 5 mins,and of course balance the budget

For all international customers reading this monster thread, I am from Australia and ordered a heap of things off Che:

Headers, cat back, adj. rear track arms and a short throw shifter.

He gave me a great price on the parts and a top shipping price (considering the size of the box)!

It arrived in a week, was packaged perfectly and all parts look fantastic. Really looking forward to installing them.

Get on board Aussies!
