welcome to the site. congrat on your upcoming tC. the trd exhaust is a nice can, in my opinion. i think it sounds really good. the price at the dealer is the installed price, and it is not a bad choice at all to include it in your deal. also, if you are mechanically inclined, you may want to do the install yourself, and purchase the exhaust from one of the other retailers and save some dough. greddy and apexi make quality products as well, will be closely priced with the trd (actually made by borla), but will most likely be louder. hope that helps. oh, and since i have the power to do so, i have moved this post into the proper forum. no big deal, just letting you know. again, welcome to the site.
