If you've changed the exhaust system you can get CEL's. O2 (bung) extensions are commonly used for this and almost always fix the problem without going to an ECU flash. thanks for the reply. Does the ECU's perameters have a limit on the lean side or does it only trip a light from the rich side? I guess the question would be, can I simply over extend the bung by about 2" to 3" or is there a "sweet spot"? I wouldn't want to guess here, best to check with your reputable tuner and I'm sure you'll be satisfied. If the extension doesn't work you may be looking at a faulty O2 sensor(s). The claim that after market products (and I don't mean to slam anyone here) are always problem/error free is not the case. However, there are many excellent products (you tend to get what you pay for with Porsche) but we consumers need to be aware of gliches that can arise. Good luck.

whats the best bang for your buck aftermarket exhaust
Camus997 replied to Porsche2ndtimer's topic in 997 TT, 997 GT2
I went with AWE and a number of others heard it and bought the same. A nice balance of sound for different driving styles. It is a nice deep rumble/burble at low rpms but if you step on it hard in sport mode it sounds like a true exotic sports car (or jet). -
This is an important issue! After much advice and experimenting, I'm running (HOT PSI, after a few laps) 38 front and 40 rears. This may vary depending on your tires, but I'm running stock PS2s. Good luck, and keep safe.

I had my "warning" for my one year scheduled check come on as well for my 07 TT. I think the "scheduled" maintenance is a guideline and definitely needs to vary according to driving styles etc. An oil change just after the "break in" period is a good idea from all those I checked with. Since I use my TT as my daily driver all year (Canadian winters included), road trips (I'm currently on a 2 week jaunt in NW USA), and track (about a dozen times a season) I will change my maintenance and oil changes done more regularly than the books recommends. I think this will be about 2 oil changes and one minor maintenance check a year, when manual recommended regular maintenance is not in effect. Good luck! C.

I went with AWE. Check out their web site for more (detailed) info (some of from independent reviewers, in their media section).

Here is some more info re outside & inside sound. I wish there was a good video of the stock exhaust sound, at various rpm, to compare these with. http://www.awe-tuning.com/media/products/a...teriorsound.jpg http://www.geevideos.com/watch/1862263217/...tt-awe-exhaust/ The sound, at least from these recordings, seems a bit deeper (I like a rumble), not too loud, and a nice howl when you step on it. Still, the Fabspeed has a similar sound, although it seems a bit louder with more of a gurgle when idling. It's hard to decide without a good quality stock exhaust set up as a basis for comparison. B) Update. I had a chance to actually listen to a couple at my tuners and decided on the AWE. A quality product with a fairly aggressive sound but not over the top for us "older" drivers.

For a fellow Calgarian, waiting for 977 delivery that will be used as daily driver all year, your post are encouraging. Have you had any trouble with sliding sideways due to large rear tires, or stopping? Thanks and keep drivin'.

Good question. I'm also considering the AWE exhaust upgrade after listening to the Fabspeed and other sounds on the internet. I'd like to know if this upgrade reduces the (small) turbo lag that still comes in the 997TT. And, does it just bolt on with no other mods necessary with no down side? Does the sound inside the cabin increase noticeably? Anyone out there with the 997TT AWE exhaust upgrade that can speak from experience? Thanks.
