taurran : "Testing new waters" with the Turbonetics ST
I like dual tipped exhaust systems. I'm pretty sure this setup with the dual resonators and mufflers, and the split immediately following the downpipe, is what makes it so quiet in comparison to other 3" exhausts.
As far as being loud, that's what the wastegate dump is for. It sounds real mean when the car hits boost.

My car does still smoke a bit. I know that Ryan was telling me it was smoking while under boost before. I'm fairly certain its not the turbo as this is the 3rd turbo that's been in the car, and each has been built with brand new seals. There's also the case of the PCV that's hanging open since it has no intake pipe before the turbo (need to fix this soon). I'm going to keep an ear out if the noise changes after the car heats up.
I think that it's interesting that Jeremy said that Larry's car made the same noise, and interestingly enough his car was smoking and seemed to have blowby issues. I'm wondering if my car has the same issue but I'm hearing its a non-issue? Larry, what came of this?

It sounds like maybe your dealing with some detonation. But that's just a guess with the noise you described.

Very nice exhaust setup!
I like it so much I think I might have Intense build me something similar for my G when I get the PowerLab turbo kit.
Is it also 3" before the spilt/Y to dual 3"? I'm thinking about doing 3.5" or 4" before the split.

The previous motor that had collapsed piston rings had alot of blowby and was low on compression on that cylinder. My new motor is a noisy one, but there doesn't seem to be anything wrong with it. The compression is good, it's not burning any oil, and the oil pressure is normal.

I've been told different things, but yes, there are way too many variables at play currently. As soon as I get my coupler in I'll see how large the difference is. I'm not saying it's the same issue as Jet's, just that it needs to be troubleshooted (sp?) one step at a time.
I am newb when trying to diagnose engine noises, but I agree with the detonation theory. Also, are you using Arias ED pistons? I heard that they were a little louder as well.
Forgive me if the above was completely off, but that would be the only two suggestions I have.

BTW, that is by far the nicest looking exhaust that I have ever seen on a Z!
