I have been searching a lot of threads but can not find the answer I am looking for. I am thinking about getting different mufflers but can not decided if I want to get the X pipe as well.

Has anyone who had different mufflers later installed x pipe? How did it change the sound? Do you get more rasp? Notice any power increase?

If there is already a thread about this that I can not find can some one please post it?

Thanks!
