My "Plan B" would be to remove straight pipe and add after market mufflers like Magnaflow or Flowmaster. GMPP looks good too, but NOTHING seems to be available NOW. I LOVE the car but it definitely needs some added "attitude" in the exhaust area!

I would welcome opinion from those with some experience in this area. Thanks all.
You know to be honest, I was told this by Scott Settlemire back in April. We were talking about this very subject and he shared with me the issues that GM had with the l99 and its sound when running in 4 cyl mode. I personally have not heard one but would have no reason to believe otherwise.
