right now I have the greddy evo catback. the noice is getting to be too much for me. I dont think it has changed I just dont want such a loud muffler anymore. Im looking for something not too expensive, not very restrictive, and not as loud as my evo. I will do some cutting and welding if i have to in order to get a "universal" muffler to fit. the main thing is reducing the noise, but not creating a HUGE restriction. whats a muffler I could use from what I have told you?
