In Reply to: Supertrapp Question for the 3.0i coupe posted by JK on January 13, 2001 at 16:04:27:

And I don't think anyone else does, either. I put two SuperTrapps on my M Roadster, and they went on fine. The folks at the shop in California (the one Karl recommends, that sells them cheap) said that they knew nothing about fitment.

So I called SuperTrapp direct. They finally called me back. And were of little help. Apparantly, their feeling is that their smallest model (4" x 17" - which I got two of, same as Karl) is good for up to 420 HP. Each one. So the lady recommended the smallest one.

But the larger ones will be quieter, so it's hard to say. I do wish mine were a bit quieter. All guesswork anyway, in my mind.


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
