That does make sense, but the weight difference shouldn't be more than a few pounds, which in such a low area on the vehicle shouldn't matter. Also, if weight was a concern you should have went with titanium and did the four tip setup which would have probably resulted in an even lighter overall package. I am sure its a great exhaust, but based on previous experience from the e46 m3, dual tip mufflers are not very popular. An example of a good racing exhaust is probably the gruppe m system for the e46m3, which was light (12 pounds) had four tips, and was made out of titanium. For me personally quad tips is a must, but you guys have sure built a nice system nevertheless.
