Pretty much brand new. It was on the car 3 days. I got a pretty fab deal on this so I'll pass it on to you and let it go for $320.00. Included is everything that came with this new (cat-back, gasket, bolts and SPT sticker). The pipe that goes from the cat to axle is under the axle-back portion in the picture.
The SPT will mate to the Cobb downpipe. As for the stock mid-pipe....STi exhaust is 2.5" and the SPT is 3", so no it won't mate. Why would you want to keep 2.5" over 3" anyway. It sounds great, and keeps "The Man" off of ya because it's not a huge can.
Is your exhaust too loud for you already? I thought I was going to go deaf in the backseat. Rumble rumble.
Hey thanks for the good deal. I got back home and took out my Megan Racing exshaust... bolt on the spt and i'm loving it. Not as loud as the Megan that's what i want.
