Borla agressive system for 02-07 WRX/STi. now $299 Great sound, ask anybody who heard it on my car. Super raspy. Pretty loud. Perfect fit, it tucks up into the center tunnel just like the stock one. The slip fittings telescope so the length can be adjusted for different downpipes. Has maybe 20,000 miles on it. It carries Borla's million mile warranty and its quality stainless steel so its not going to rust out or anything. Its kinda dirty, I should probably clean it. The tip will still polish to a mirror finish without much effort. It has a flat flange on the end of it so it will not connect to the stock downpipe.
It has a slip fitting between the two parts so you can't separate it into a mid-pipe and axleback. Makes for smoother flowage, yo.
