986 Exhaust Question!
I have a 2000 986s that I am going to upgrade the exhaust on and would appreciate some advice/ recommendations. The car has been solely used for track day/ HPDE events for the last two years. I have seen a lot of good comments on the fabspeed, and have been looking at those. The question is, which of the following would be better?
Porsche 986 Boxster Supercup Exhaust System
or Porsche 986 Spec Boxster Competition Race Exhaust System.
The car is only for track use. Anyone have any advice? Are they both direct bolt ons without modifications? Will I have any issues with a check engine light? Any other companies or systems I should check out?
Thanks in advance for the help!

If it's a track car, the lighter the better. I would run straight pipes if your track allows for the noise, or perhaps one of the Fabspeed, or Borla duals. Simply doing headers makes a worthwhile difference, but adding a race system would be golden, and I don't think any ECU mods are required as long as you leave the O2 sensors in place. A custom tune might make a bit more power. Most driver cars have issues with drone with the twin systems and a popular exhaust is the FVD Brombacher system.
Just to update, the Fabspeed race looks to be the perfect setup, good price too, but need headers it looks like. 36 lbs is a ton of weight off the back end!

If you are willing to pay the price get the full service you are entitled too, call Fabspeed to see what they say. Usually a lead time to make the parts too.

Interesting thread.
Hope it will still develop here, not over PM !
In my case, before looking at exhaust, I started with intake !
AFe performance filter, big intake pipe (fm IPD), 74mm throttle box and IPD plenum.
It does take a difference, no idea how much on HP, ..but more than one sec at Laguna Seca. (Have more than 1,300 miles driven there.)
May be this is also the reason that I did not touch the exhaust, as most of the track days there are 91dB limited !
Still, I have envy to change the exhaust headers as the OEM one is so restrictive ! It is like it has been designed to have limited flow out !
But, I have fears to touch the sound barrier of Laguna, where I love to drive around !
It is also a pain to keep the end exhaust, that is real heavy, ..OK, positioned low, but really far on the rear !

If it's solely a track/HPDE car, I'd go for the 986 Spec Boxster Race Exhaust 
You'll pick up approx. +15whp along with shedding 36lbs from the rear of the car. Exhaust tone is dramatically improved as well and the system includes turn-down tips to help pass track sound limits. No Check Engine Lights either on a 2000 986S either.

Alec, ..Love it big time, ..but would like the same but as "soundproof" as the original.
(Beside the Laguna Seca 90 dB limit, I do NOT like the noise at all, but I love when it is as light as possible ..and as less restrictive as possible !!!)

Nice car : ) Starting in 2000 and going to 2004 (986.2) the primary catalytic converters were moved from the inlet pipes into the header assemblies. However, a secondary set of redundant cats were kept on the inlet pipes to the mufflers. What we can do is keep your factory headers, keep your factory muffler, and ditch those secondary cats assemblies with bypass pipes. This allows you to drop a good bit of weight while providing just a modest increase in overall exhaust sound. Now, I've had 987s running race headers and maxflo exhaust systems pass Limerock DB (pretty close to Laguna) with turn down tips, so I actually would bet a full Maxflo system with factory headers on your car would pass at Laguna. But if you want to play the safest route possible...secondary catbypass pipes are the way to go.
When you have some time, give me a call at 484 883 6197. We can go over it a bit more in detail and come up with a game plan for you : )

yes, I love these Boxster, so well balanced chassis.
Im going to try a special design of headers, with balanced larges tubes, the 3 going directly into a large good cat (before the 3 in 1).
(other side of cat going into the oem "connector") that continues to the inlet tubes (Basically, the cat doing the role of the 3 in 1, ..a Swiss design tentative ! )
See : the 3 tubes goes directly into the cat, soldered on a triple holes, cut on a steel circle disk adjusted at the size of the cat.
(laser cut, you can see a spare part in the middle). the trick is to have such "cat entry" instead of going into a 3 in 1 (the original 3 in 1 is cut and also stay in this photo).
Basically the idea of such design is the replace the 3 in 1 by a cat !
The wood base is to keep the overall position and dimension the same, this to have a bolt in header at the end of the soldering sessions.
Will see what's happen with the noise with such setup.
(If you are looking at the oem header, it is realy an awful design, very very restrictive. I read somewhere that this header was badly designed to be sure the 3.2 of the "Boxster S" will not compete too much with the one of the 911, as anyway, these two parts have to be different between the two model coz position of the engine. Or, a cheap way to keep the same M96, and make one a bit low perf ?)
If still ok, then, may be I will not going with secondary cat bypass (fears of too much noise), but will go for a solution with secondary 200 cells cats.
For me (as less noise as possible guy, ..but also as less restrictive as possible AND as light as possible !!!), the problem **is** the end muffler, simply because it is very heavy.
I would love to find one that is as silent as the oem one, ..but much much leighter.

Getting close to be able to try !
The modifications are done, and as you can see, replacing the "3 in 1" by a cat, that get straight intake from the 3 balanced exhaust pipes, and then a light cone going into the exhaust pipe goes in place easily (that was my idea in the design of this version).
As you can see, still missing the O2 sensors connectors, this will be done before tests.
Will try and see what's up !
Goals : efficiency via balanced length tubes and easy flow, cats staying on line to be environment as friendly as possible and be as silent as possible, I'm NOT a making noise guy.
In term of overall flow, I have a performance intake filter (AFe), a large intake pipe (IPD), a large throttle box, matching IPD plenum, so, logical that next in the path is work at the exhaust headers !)

What I would REALLY love to find in the market is a "rear" muffler that is very light, ..but still being fully sound absorbing.
(My strong belief is that making noise, beside showing the need of attracting attention, is simply creating nuisances and amplifying the number of enemies to the auto sports.)

I did install the setup above and for me, the results is real great : Almost zero additional noise, but I do feel that the engine is "more happy", I get the feeling that I have a better "rpm up" !
For me, the best check is Laguna Seca, ..i.e.: simply reading the lap timer ! Will check that as soon as possible !
