This was on my wifes car (05 WRX wagon), that we traded in on the SUV she had always wanted.
Anyway, the QTP downpipe was seldom opened unless she was in a high spirited mood, so it has little wear and tear, and more importantly it still seals up perfect. No leaks at all when the cutout valve is closed.
QTP downpipe $250 plus shipping... these are $505 new, so half price here people!
I also have the QTP cutout controller for $60 plus shipping.
Package deal for both is $300 plus shipping.
