30 wheel hp, so about 50 crank hp. Your right. The gts should have just added a full exhaust (which it did) and forget about stroking the motor to 4.4L to make 450hp. They could have done it with a "tune" and exhaust!

People really are suckers for these bogus hp claims. Maybe 10hp from cat delete. 10-15 with cat delete and a tune at the wheels. No more.
Man you really are an idiot!!!! It is well documented by numerous dyno runs (that you can view in the dyno database at bimmertech) that a full exhaust does indeed add 20 to 30 WHP, if not more in some cases.

By the way, the GTS don't have a full exhaust, it has a different rear muffler. The mid section is the same as any other M3 including those restrictive primary cats that when removed are the source of the gains.
