What the other thread is a “about” doesn’t really matter.
What Mike is saying that the e30 exhaust could benefit from a flex joint just aft of the down pipe. He’s justifying this modification by stating it is less prone to cracking the down pipes and causing exhaust problems in front of the driver, and is thus a safer design. He points to an issue that happened at the track here in Norcal last weekend where a driver suffered from CO inhalation after an off (see above).[/quote]
Adam/Mike,
My point was not to “split hairs”. If as you say, Mike was interested in having a reasonable and positive discussion about a potentially dangerous situation he could have stated his concerns as you did instead of “this POS spec exhaust is well beyond saving money…And it is so stupid load you can’t hear if it is cracked.”
I don’t know you Mike. I’m sure you are a great guy and you certainly feel passionate about the situation and that’s great. The exhaust issue experienced by Will is concerning and worthy of review and discussion, but inflammatory posts that shout conjecture will not help solve problems and prevent incidents like Will’s from happening again.

I totally agree and sorry for getting worked up over it. My excuse is that I have been present when people have died at the track due to passing out for one reason or another, a likely reason being CO poisoning. One person who was involved in one of the accidents and also lost his life was a family friend on my wife’s side. I did not know him personally but any conection to someone who dies doing the sport we all love hits home just that much harder. My brother also had a very scarey bout with CO poisoning in a 600 hp time attack car about a year back, and if it hadn’t overwhelmed him so quickly, he may not have known what was going on and things could have been different.
Another reason for my frustration is that IMO a spec exhaust in conjunction with all the other motor resrictions is a drop in the performance bucket. With a 2 valve per cylinder head, stock airbox, stock exhaust manifolds, and no engine tuning or building outside of factory specs, within reason the type of exhaust will not change the output of our engines significantly if at all.
Why not simplify the rule…“exhaust must be constructed out of a single pipe and muffler with an ID no greater then 2.5”, with the collector positioned at or before the first crossover in the factory exhaust."
That way if you want to roll the dice on the current spec 1 piece exhaust you can, or you can build your own to your standards of safety, fitment, and sound. I live in CA and would love to bring my bimmer to Laguna, but it will never pass sound.
According to the SE30 guys in my region, the spec exhaust is very good performance wise. Some amount of dyno tuning went into its design. The good news being if the rule is changed, the current spec exhaust will still be “the best” system you can buy performance wise, and you would not have to spend a dime to stay in compliance or stay competitive.
My argument in a nutshell is why force us to run a part that can be dangerous in any situation if it has little to no influence on our cars’ performance.
