My 98 GT has a hi-flow catted h-pipe and 2 chamber flows right now. Sounds good, but too "tame" for my liking. Is anyone running Spintech Pro Street mufflers with a catted mid-pipe? I want something louder and more aggressive sounding. I'd like to leave on the catted h-pipe, but I want a more aggressive sounding muffler. Personally I really don't like the sound of SLP and I'm not a huge fan of Magnapacks either. I've listened to a couple of sound clips online of the Pro Streets. I think they sound pretty good from what I can tell by listening to a sound clip but I was just wondering if anyone has any experience with them personally or know anyone that has them. I don't want to make my car sound like a beat up garbage truck with a rusted out exhaust
