u can get a cat back made up 2.5'' and a muffler that doesnt drone. plenty out there. i have a varex. best of two worlds and for that system abit less than a CES exhaust. up to you but CES is a direct bolt on the car. the painted calipers look good... after 6 months they get dirty lol. yes the stock leather is sh#t. i will retrim mine sometime down the track. be prepared to fork out around 3k for it though. not worth it unless u plan on keeping the car for a long time. sound system better get a pro to install it for u. they can neatly tidy up the cables and stuff.
