Just get the module that plugs into the wiring harness and tricks the ECU. That's what everybody else does. I have an aftermarket deck lid myself. No error lights... I'm using the module. If I'm not mistaken, you can buy the module from MA Shaw, Anziano's, etc.... That's what I did. I don't know why techart does things the hard way. How many body shops have access to the porsche diagnostic computer? I think the module is like $100 or something like that. You can still send me a gift for my good advice

 

Deputy - I will check into it. No body shop on Maui has the porsche tool not even the porsche tech on Maui. Check the mail your gonna love this package.

I tried that deputydog, with the 997 it is different. I actually found out that I didnt need the other module.
All you need is to have the dealer hook the car up to the machine, it cost like $75-150.

 

read above post. they don't have the computer where he lives.

did you actually try using that module and it didn't work or did you just decide not to use it when you found out they could do it on the computer?

 

I'm having my exhaust tips powdercoated this week. Should be ready for pick-up on Thursday evening. I'll post pictures.

 

Got them powdercoated..will take better pictures in the daytime tomorrow.

 

wow those loook sweet atomic

 

Looking Good!

 

Well, I went on a drive with some BMW and Porsche guys today and after some hard driving I discovered that the extreme heat had burned/melted the powdercoating off!

I'm having the tips ceramic coated this time....hopefully it holds up!

 

Ok, you didn't believe me the first time when I said PC'ing doesn't work.

Maybe you'll listen this time

Ceramic isn't going to hold up either. It does hold up against the heat better but it is very fragile compared to powdercoating. The tips get exposed to way too much road debris.

I've already been down this road.

Black Chrome is your friend

 

Yeah yeah yeah, I should have listened. But however, I'm wondering how you can say that ceramic coating is fragile. A friend of mine has a Dinan M3 which happens to have ceramic coated exhaust tips. After 35,000 miles, it still looks great. Seems to hold up well against chips, etc.

I'm now hearing about a new option called carbon nitride. Not sure what that is but I'm told that it'll hold up quite well.

I'm not sure if I want black chrome because of the "shiny" properties. I want something with a "matte" finish.

 

I can say the ceramic doesn't work good because I already did it. That was the first thing I tried. Within a month they looked terrible. I am not sure why you're buddie's M3 worked out so well. Maybe it's where his tips are located or the aerodynamics of the rear section of the car deflects debris? I don't really know.

I have no idea what carbon nitride is. Is that what they used to freeze hans solo in?

The black chrome isn't as shiny as you'd think. It looks more like a glossy painted surface with somewhat of a mirror quality to it. I really like it. I think you'd have to use untreated virgin tips to do it propertly since it will show the surface imperfections easily. My tips have been prepped and treated with too many things at this point I'm sure. I need to get a set of stock tips off ebay and try it soon.

My most recent attempt at making this work was some secret process my dealer uses. He didn't tell me what it was. It was flat black and has held the best so far, although it too has shown signs of wear after about 6 months.

So to summarize, here's what I've done so far:

High temp paint: Flaked off almost immediately
Ceramic coating: Ditto
Powdercoating (2X): Melted off in a very short amount of time.
Secret dealer coating : I have some time on these now, but they are starting to look rough too.


Like I said, if I can find some 02 tips cheap, I'll give it a whirl with the black chrome. If that doesn't work I'm throwing in the towel on this one.

I'll give you guys another piece of advice. Whatever you do, don't drive the car without the tips (ie you've sent them off and you're waiting for them to come bacK). Let's just say, it ain't pretty and I'll leave it at that

I'm wondering what sort of ceramic coating process was used on your tips. After all ceramic tiles are used on the Space Shuttle for reentry heat protection. As I understand it the exhaust temperatures on the 997TT reach as high as 1100 degrees F. So heat is definitely the problem here. The coating process used and quality control of the process is critical.

Your thoughts Deputy?

Most likely it's the temperature difference. The M3 exhaust doesn't see anywhere near the temperatures generated by the 997TT. As far as chipping or any sort of other degradation due to road debris, the Dinan exhaust tips are right there in the "debris field" and have held up like new for 35K+ miles. They tend to get very dirty in wet driving, but clean up nicely.

BTW the whole purpose of the ceramic coating on the Dinan tips was to prevent a mismatch due to discoloration. As you may know BMW's signature on its' M car's is a dual quad exhaust. Dinan's muffler only has one side that is used. So, if a chrome or similar finish were used, the active side would show wear/use while the other would not. With the ceramic coating this not a problem.

 

I don't know what specific type of ceramic coating they used on mine. It sure did look nice when I picked them up at the shop though.

I have an EGT temp gauge on my car with the sensor just aft of the headers and temps get wayyy up there.

That chromex looks like an interesting option. It would seem that their satin coating is even more durable by the product description.

Again, the ceramic is great for heat. No issues there. I just found it to chip away very quickly. Mine did not have the durability of power coating. On the flip side, the PC did not have the heat resistance of ceramics.

Give it a try and let us know how it works out. I'm still going with the black chrome when I can get my hands on some cheap test tips.
