OK, now are the pro's and con's.
- No reason to change your stock exhaust if you have an NA unless it's HEAVILLY modified. Doing so can actually hurt performance.
- Turbo cars can greatly benefit from a free flowing exhaust but the stock CT26 really doesn't move enough air to justify it.
- Single exhaust setup is lighter.
- I agree, the single does sound better (turbo cars only)
- Single is cheaper than an aftermarket dual.
- Huge selection of mufflers if you choose a single exhaust.
These are just a few things that come to mind after only one cup of coffee this morning but if you would like a more in-depth discussion on this subject, I would be happy to explain.

Scott I don't know where you're getting your information but the bit about NA engines not responding well to exhaust is incorrect.
Even just a cat back exhaust will result in nice gains, header back results in significant gains on an otherwise stock motor.
It is true that an INTAKE doesn't result in gains unless you've also got other VE (volumetric efficiency) mods such as cams or port/polish.
