Happy holidaze everyone!! I have a quick question. I was thinking of getting flowmaster exhaust for my baby full-size Jimmy. I was told that flowmaster is very loud and obnoxious but that there are units that reduce the resonance to make long drives and respectful passengers not so endowed with perpetuated rumble. Does anyone know where these units are being sold? I was told they're about 30 or 60 bucks and they work well without inhibiting the flow. If not, where do they sell the quieter flowmasters? Thanks to anyone who reads this. I love this site!! From Dave, y mis dos perros, Beaucoup and Shaka.
