RE: flowmasters or slps
its amazing how much everyone hates the flowmasters...... ive been more than happy with the sound and i didnt notice any loss of torque when i put them on, and i have original 40 series in my II and it sounds wickedly awesome

I put American Thunder Flowmasters on right after I got my 2006 GT, I have had many compliments on how it sounds. Great middle and top range sound. Now starting to wear in and rumble deeply.
