How come the exhaust in the GT4 pics in the brochure looks like it has a large muffler similar to the stock muffler, as opposed to the 2 discrete mufflers in the E9X M3 Akrapovic after market exhaust.
I would have expected a similar Akrapovic exhaust to be used in both applications, i.e. after market and GT4.
Actually, the exhaust on the GT4 that Turner Motorsport acquired looks like the regular after market Akrapovic exhaust.
