Not a fan of GMMG exhaust, yeah it sounds good but im running longtubes and custom True Dual Exhaust w/ Moroso Spiral Flow mufflers which sound amazing. I'm already on ls1tech which is the only fbody related forum im on lately. I stay on streetcarforums alot and here mostly. I would join you at the Gathering but i'll be gone to Fort Hood on April 1st so thats a no go.
