Best Turbo Exhuast Setup?
I'm trying to figure out my options for selecting a turbo exhuast. I was wondering if someone can shed some light on this topic.
I understand that 3" is optimal because the exhaust flow is fast enough.
Exhuast Basics (great article for those searching w/ the same question in the future)
However I've seen these three setups and would like to know the differences:
1. 3" single (loud?)
2. 3" dual
3. 3" dual until the 'Y' and then 2.5" thereafter.
Specifically, the last one interests me. A local had a Thermal R&D custom built with this type of setup. Here is what he told me:

Hi Tan,
I had a question about your Thermal Exhaust. Why didn't you opt to go for 3" all the way through (including past the 'Y'). I would think the 2.5" piping would impede flow for FI.
>>>Because I was told with the dual system 3" would be too much. If it was a single, 3" would be optimal but not with the dual. Also, with my HP, 3" dual all the way back was a bit excessive and a bit loud. I also had a UR 3" dual before this and it didn't sound what and felt slower thumbsup.gif
**It should be noted that he was running a Comptech supercharger w/aftercooler at 9.8 psi
-Does the fact that a supercharger only "pushes" air vs. the "push&pull" of a turbo make a difference?
-Am I suffering significantly w/ a highflow cat vs. testpipe/straightpipe?
-Lastly, if the Thermal setup is ideal for my purposes (LoveFab GT1 GT3082), what would be a fair price for the setup?

I'm interested in this question too... I have a friend who owns a dodge SRT-4 and about the only thing cool about that car to me is the fact that he has no muffler... from the factory the SRT-4 runs its exhaust through the downpipe, past the converter, and straight out the back with 3" tubing all the way... I am curious if a simular setup with the S2K would be too loud? Anybody know?

I'm not to familiar with the SRT-4 or what kind of turbo / piping it has but in a s2k, no mufflers means your going to break windows its so loud

Maybe it is a custom job? I agree, it must be very, very loud.
Tyraid2K: I'm curious on what you based your decision to do this on, instead of going 3" past the Y-split
