Anyway, I got rid of the Celica back in 2007. Cleaning out the building a few weekends ago, I found an exhaust I used to have on my Celica. I can't remember exact details since it's been so long, but it's some kind of HKS if my memory is correct. I *think* it'll only fit GTs and not GT-Ss. Here are a few pictures of it.
I'm located near Greenville, NC, if anyone would be interested in it. Not sure how much they go for anymore, so I guess I'm open to any and all reasonable offers.
