Aside from noise, weight and dyno tests that I have not seen,.. do cans like MBRP, GGB or others actually improve performance. If flow tests/gains can be proven I want one. Why don't companies divulge information, is it because they don't improve performance?
I had an MBRP trail can on my XM,.. don't know if it was better because I took the stock can off as soon as sled got home.
