Maintenance and some other issues???

Hello again,

First issue: rattling noise coming from the exhaust area the exhaust is new from Che's product, also, I have his headers which will be installed soon. In regards to preventive maintenance my car has 47k miles on it I recently did an oil change which wasnt an easy thing to do but I did it. I must say that I need the proper tools to do that since I was lacking a few tools. Would it be a good idea to change to 02 sensors once the new headers be installed? Also, do I need to replace my rotors at every brake wear? Whats a good indicator that the rotors need to be changed? I have some wear on the rotors but I am not an expert to determine if they need to be replaced.

Lastly, I have a noise coming from the suspension or some other place everytime that I park my car in the garage and I go over a cement ramp I hear the squeaky noise I have an extended warranty on the car by (Easy Care) which is bumper to bumper should I just take the car to the stealership and let them deal with it and do an inspection on the car? I dont know what to do with this ride, shes a keeper but I to deal with a few issues. I paid over $3,500 for a warranty on the car wondering if it was worth it

Been looking around ebay for parts, tools etc so I can work on my car and save some money but I need a little guidance on this. Whats a good torque wrench to have? Damn so many questions

What year and engine size is your boxster?
I have Che's muffler on my 02 S and it makes a rattling sound as well. Porsche dealership said it was coming from inside the muffler, maybe a loose baffle.
I have had mine for 6 months and it has not gone away. Maybe if we both call Che and tell him he might be able to fix it or send a new one out.

I dont know what year yours is, but be carful, my 02 S has BOTH O2 sensors on the headers, and therefor NO after market header will work without a CEL.
Che was working on a solution, but the computer is looking for a O2 sensor before and after a cat converter.

Do it, they come with a warranty for a reason. If he sold you the muffler and it didn't state, 'Muffler comes with a rattle', then you should be entitled to a free replacement. Let us know if Che takes care of you guys or not.

I would guess the muffler is rattling, but I traced a rattle to the TTP headers that I have. The bends in a few of the pipes are very close together and at lower RPM's, they can rattle. Also, I just got a Dansk Sport muffler and there is some rattling that comes out until the engine warms up.

You can always eliminate the rattle you have by placing a spot of weld between the 2 header pipes that rattle, thus linking them and stablizing them which eliminates the rattle.

exhaust

I have a 2001 S Speed Yellow the old oem muffler did not make the noise I will have the dealership check on it. Also, I purchase the headers from Che and now I am concern about the 02 sensor issue why would he sell something that wont work on the boxster i dont know but now I am freaking pissed off. He said that it will work once my mechanic verifies the info i would let you guys know.


Thanks

Well the more I looked into it the worse it got. The bottom line is that I have 4 O2 sensors, and 2 must be before the cat, and 2 must be after it.
For Cheís headers to work in MY car, I would have to have the mechanic drill and weld a bung in the secondary pipes. Two before and two after the cats.
As you may notice Che's headers do not have a Cat in them like fabspeeds, so you must move your 4 O2 sensors down stream a little into the secondary cats, before and after. This requires lengthening the wires to the O2 sensors.
I have heard that with longer wires comes more electrical resistance in the wire, and thatís how the O2 sensor send information to the computer. This will lead to a wrong value and a possible UNFIXABLE cel.

If you have this situation, and you want after market headers, then buy the fabspeed ones with the cat and then have someone drill and put the O2 sensor after the Cat, and hopefully you wonít have to extend the wires much, and it would only be to 2 sensors rather than 4.
