Hi, I have been contemplating upon purchasing an Exhaust System. I own a 2001 330CI Coupe BMW and I was wondering which exhaust system is better. When i mean better I mean will best improve my cars sound. The sound I'm looking for is not like those Rice Rockets "Rattling, high pitched" I want more of a European muscle sound, " A deep Grrrrr!" Also whichever exhuast system will help my performance more. Please lend me some advice...The exhuast systems I'm pondering between are Remus and UUC Motorworks. Unless you all have other companies in mind that will fit my needs, then tell me about those. But I need help in choosing a Cat-bac performance exhaust system! Please help!
