The car looks great!!! I love the facelifted rear end!
Did you buy the system used? The pipes that slip over Eisenmann's connecting pipes get compressed during installation, so if you're reinstalling a system that's already been installed, the best thing to do is to get a pipe spreader and open the piping up again, then slip the exhaust system further down on your Eisenmann connecting pipes. It's definitely possible to tuck the system in further- there is a surprising amount of adjustment in the exhaust.
Please give me a call if you have any other questions or need any help at all. 866-963-4520
