We just installed my Mozart last night I have never heard such a loud exhaust ever. Let me just warn you all now, its a nice simple bolt on exhaust thats cheap and light weight BUT it's loud as heck. Under daily driving you have to keep the rev's at 3000 up. I attempted to shift from 1st-3rd-5th and that did not even shut this thing up! I do like it (no choice, I paid for it and its on my car). Just the weight savings and DTM tips make it worth it.
