Are you looking for stock or aftermarket? If it's stock, go to a junkyard or be prepared to shell out $1K. If it's aftermarket, no company makes one yet. You'll have to go custom, using the stock midpipe from the header to the cat, and then the custom part after.
well the thing is i got a tanabe rear section and the weapon R race header for my GTS. I didnt realized the midsection stock section are welded with the stock pipe. I guessed if that my only option i would have to look around if there anyone who is willing to do that for me. Anyone in Mn or in the mpls, st p area who know anybody who are willing to do it??
