I just purchased an 08 xt in Blue recently. Pretty much same condition to yours. Nice work on your car. I just did a cat back on mine using 2013 wrx sti midpipe and mufflers. Its quite nice actually. no drone, not loud and has very nice sound. Im gonna get a piture up as soon as the forum lets me. I would recommend a cobb tuning catted downpipe, i know they are expensive (650.00) but, the results speak for themselves. Are you using a cobb accessport? just curious...
