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.
