Exhaust issue for 2009 G6 Convertible

What do you do to increase the exhaust size to 2.5" when the crossrods are in the way ? Tried to have my exhaust replaced from the cat-back and can't. Getting a Magnaflow Camaro Muffler and tips installed today at least.

FYI... The Magnaflow Muffler was a little louder than I wanted and the car doesn't run as good either. Don't know why. My Sunfire with the SC3800 runs and sounds great with the one it has from Magnaflow. Going to have to re-think this.

It's because our cars need a certain amount of back pressure in the exhaust to get power in the low RPM's.

Is there a fix for that ? We are going to replace the resonator with a torpedo (turbo resonator) to add a little back pressure and hopefully quiet the exhaust down. What do you think?
