Thanks for the reply and hanger link. I am going to buy it (STI cat back). Cost about $95 and looks quite clean. My well used stock XT exhaust is now leaking with 260,000 KM on it. Good service. I was hoping to remain stock, but the dealer wants $1000 CDN to change the center pipe. Anyone know of a Canadian source for the hangers? They want very high tax and shipping for those. Would wind up being close to $100 USD landed.
I believe it had to do with the length of the STi exhaust being short on the Forester... the tip didn't extend far enough under the bumper. Some members reported bumper skin discoloration or melting from the the hot exhaust.
There's a picture of the installed shield on this post.
