  1. Thanks to all for the suggestions, I've been out of town so haven't been able to look yet. The pictures are most helpful. @raceken your hi res pic is nice but I'm a little disoriented since everything is out of the car body--do I have to remove the engine from the car to find what you're referring to? I don't mind having the sport exhaust on at all times. But I wonder whether I just need to get a new exhaust (maybe non OEM that is louder?). Will check car this weekend to see what is up so I can report back!
  2. Thanks for thoughts--how do I remove the vacuum lines from the mufflers and plugging the lines, or disconnect the electrical connection to the solenoid?
  3. Well, my sport exhaust went out again after tracking my car--this seems to only happen when i track it! This is the 3rd time it has gone out now, and the dealership can't seem to get a permanent fix on it. Here is brief part replacement/history: 2011: R sided exhaust diaphragm leaking so was replaced (under CPO as this was right after I bought it) June 2013: sport exhaust went out after tracking car but spontaneously recovered so nothing replaced Oct 2014: solenoid was replaced after road america track days killed it Oct 2015: nonfunctioning again after blackhawk farms track day (driven <1000 miles since Oct 2014). I did hear a 'doin-gggggg' like a spring coming loose as I was making a corner so not sure if this is what broke it or not My questions: 1) it seems these cars commonly have sport exhaust failures--is it impossible to permanently fix it? i.e. is it worth paying $$$$ out of pocket to fix it if it might just go out again? 2) how difficult is it to diagnose myself, like using Loren's diagram? I am unfortunately not that handy with DIY but could go back a jack if that's helpful. could also bring to local indy/friendly dealer to put up on jack but will I be able to find the problem easily? 3) is it better to just be a new sport exhaust entirely and if so, which one would be recommended--a louder one than OEM would be ideal!
  4. Thanks, will do! Now the question is, should I also replace the rears to match heating cycles?
  5. Cut the wall of my left front tire on the out track of turn 7 of Blackhark Farms Raceway today (apparently they put speed bumps just past rumble strip to discourage cars from braking too little). Kind person gave me a spare to get home. I'm currently using MIchelin super sports 235/35/19 for all four tires. They don't have a lot of wear on them as it's pretty much a track car only for me these days--I've put maybe 4 tracks days on them (including 2 days at Road America), probably 1-2K miles max. Do I need to replace both front tires? Or is it ok to replace just the left front?
  6. Thans Ahsai, I read the other threads on this but just want to clarify 1) is a leak the same thing as RMS/IMS 'failure'? 2) if I don't fix it will it lead to failure? 3) is taking the car on a track a bad idea if it's just a few droplets I see on the garage floor? 4) is it even worth fixing this? I saw one post where someone said it was a simple leaky connector and solved the problem, and someone else said not to worry about it because the car may never be the same once transmission/engine moved
  7. Also, my coolant was quite low a few months ago and thanks for people on this forum, I changed the plug for it and topped it off. Level still looks good today.
  8. Was getting my 2007 997 C4S teched for a track day and my indie guy found this moisture under my car--it is in front of the oil drain plug (magnetic from LN Engineering) which looks fine. Since the last oil change a few months ago I've only driven my car 3 times (total 10 miles or so), and I noticed a tiny amount of fluid in my garage underneath this same area. Oil level is completely full. My indie guy is a BMW guy but thought it's maybe rear main seal? Neither he or I know though. Does anyone know where this is and should I be worried? Should I cancel my track day? What should I do?
  9. Thanks Loren and RFM, ordered the cap and porsche antifreeze at suncoast!
  10. Looks like the coolant on my 2007 has run below the 'minimum level' (see pic). My questions: 1) what is current recommendation for low coolant? Is it ok just to add to it or do I need to do some sort of 'flush' as described in this thread and if so how do I do this myself? I don't need to take this to a dealer right? 2) for coolant type should I buy the one on amazon in this thread and mix with distilled H2O? Is it a 50/50 mix at room temperature to add? Best Elliott
  11. ok thanks for the suggestions, will check both the brake fluid and pads!
  12. btw--the local guy told me over the phone that ceramic would be the way to go, is this other people's suggestion? Anything else I need to be aware of that needs to be replaced when new pads are put in?
  13. My 2007 C4S has been on the track 3 total days now and total of 24,000 miles but since the last track event I've noticed the brakes have been a little softer than before. I assume this is a brake pad issue? I'm bringing it in a local indy dealer to have checked out but next question is which brake pads to replace? I got it CPO but I think it's stock with red calipers. Few options I've heard of: suncoast performance friction hawk Anyone have experience or recommendations for these? About how much should I expect it to run for brake pad replacement including labor?
