exhaust system problem
I have a 2007 Convertible G6 that is making the whistling noise on acceleration. I was wondering if the convertible exhaust system is the same as the Hardtopo version. I want to fix my whistling sound by deleting the resonator and replacing it with a magflow system i guess? Any help here would be great. A lot of people recommended deleting the resonator but i believe they had hardtops. Just wanting to make sure both models have the same type of exhaust. I had heard that my convertible model has more bracing underneath than the hardtop.
