Just installed the CTS Turbo turbo muffler delete and I gotta say i'm not too impressed with the CTS kit. Due to the size of the new outlet portion of the turbo, the N75 valve has to be shifted away from it to have the hose fit on. They include a small bracket to do this with 4 holes. Two in the stock location, two shifted diagonally away from the turbo outlet. Aside from it being a pain to get the bolts in the holes on the turbo, the top holes were too small, and not threaded, and there was no hardware such as nuts to secure the valve to the bracket. I ended up just using the smaller vacuum line they gave to hold the valve in place. Doesn't seem like it will be going anywhere and i'm really not concerned since I plan on getting a different turbo down the road. Just would have been nice to have a bracket actually work. I also had to re-use the original O-ring since the "included" one wasn't actually included. The main reason I installed this was to get better fitment on my TOP which didn't line up with either of the bolt holes on the engine. I was able to get one of them to line up so while not perfect, it is definitely secure on there. I have yet to drive the car since putting it on but i'm really not expecting any performance difference from it. I definitely wouldn't recommend anyone getting this from a pure performance standpoint. While the install wasn't really difficult, it was definitely frustrating enough where I wouldn't do it again even for a slight performance increase, which again I doubt this will give.
