Since the 3.0i is essentially a dual exhaust up until it reaches the mufler, what kind of custom exhaust should I consider for my 3.0i Coupe? I may consider using two Supertrapp mufflers and make something like a dual exhaust similar to the M's Left and Right placement. I also got the part number for the supertrapp for the 2.8l, will 2 of these work for me? Any other advice or suggestions would be helpful! Thanks
