So my car came with Gemballa mufflers installed by one of the previous owners. Generally I like the sound, but wouldn't mind it being a little louder. I have thought about perhaps adding sport cats, as I hear they generally raise the overall sound level. However, I probably need to first compare side by side with a few others (PSE, Fabspeed, etc.) before making a move one way or the other. While I know a video clip is not the best for sound comparisons, I welcome any comments on how you think the Gemballas might sound vs. other systems.
