Ok, when i bought the 89 I have it had a huge glass pack on it thought it sounded good. Since then the tail pipe is no longer in use, oops, and it seems that the glass pack is next to leave. My problem is i don't want to loose performance by getting something else cuz it does good with what i have, but it is just way to loud. Makes my neighbors a lil angry with me. Thinking of getting the 27.99 THRUSH at advance. I have read it has good performance and decent sound. Anyone have any comments, and or life lessons on it?
