thanks to Toykilla i got these installed today!! All i can say is WOW, these things make the borla sound a lot deeper. The car seems to be more responsive when i hit the gas. i am still breaking them in as i only put about 30 miles on them so far. I will definitely keep you guys posted as i put more miles on them. We did have one problem the driver side test pipes was hitting a heat shield and rattleing but i can just bend the heat shield and it should be fine. Overall i would definitely recommend these as long as you dont care about the smell.
