I have an 04 Comp G that is beginning to feel its age. I just replaced both front hubs (it has 120,000 miles) and it now needs a resonator and the struts are original and are due for replacement I have only had the car for 3 years btw. Also, while I do really like the car, my plan is to keep it for another year and a half, then give it to my daughter when she graduates college. My hope is to then get the car I really want, an 05 or 06 GTO.
First question, which exhaust system will sound and perform the best, without costing an arm and a leg. Next, which are the recomended struts to keep the handling and ride at least as good as factory? Is the stabilitrak in any way connected to the strut type, or is it strictly a braking issue.
I am actually quite surprised at how well this car handles, as I usually had rear wheel drive performance cars, TA's Mustangs etc, and did not like the handling of a 03 Monte Carlo SS, which supposedly is on the same platform. I want to keep the handling the same as my daughter also likes the car.

Thanks for any help.
