Stopped by the dealer to see the new 05's up close. I have an 04 myself and wanted to check out the dif. between the two other than the ls2. As I lay on my back to behold this new and "improved dual exhaust" that dumps on both sides like all the (can't think outside the box) gear heads like and ensist on. A great smile lights up across my face, I's that, NO it cant be, YES it is the dual exhaust (both sides) going into ONE, UNO, muffler then comming out w/ 2 outlets and going into two more mufflers (one on each side) right before the exhaust dumps out. As good as it may look coming out on each side in the "traditional hotrod fashion" I'll stick w/ my TRUE DUAL EXHAUST dumping out on the driverside. Thank you Pontiac for keeping it real for 04.
