The mufflers look exactly the same as best I can recall. All the parts fit and work fine. The only thing that had to be fabricated was an adapter to make the 2 1/2" pipes connect to the 2" CTS pipes. The exhaust shop needs to be careful if they cut the pipes in the same manner as mine were done, so the length is correct (I'm sure that is obvious to an experienced exhaust guy). Cutting them behind the sensors on the CTS pipes eliminates the problem of having to install the sensors into the CTS-V pipes and possibly messing up their function. If you use a good exhaust shop, they should have no problems.
