Had a friend of mine install a 2.5 inch flo pro on my vibe last week..It went pretty smooth and I opted for the opposite exhaust exit from stock because my egt temps were reading a little high and wanted to get the hot exhaust out a lil more quickly..Increasing the flow decreased the temps by 150 degrees, just in time for summer. http://www.flickr.com/photos/4...tream/

It's a little loader than I prefer, no power robbing res, but when I had it at the dragway it all made sense, it ripped and wasn't very load compared to most of the other cars there..you like that huh!? haha, cooled my egt temps by 50 degrees.
