I'm a bit disappointing after hearing it, no way near n55 sound....I know it's 4 cylinder, but still....
Only when the exhaust valves are open, does it sound really nice & upgraded compared to stock or closed. Thing is, the quad tip is really 'cheating', coming off the single muffler. Then again, I've had second thoughts and I would LOVE to get the 4, just for the looks.
The 2 tip GTC with electronic valve is US$2.5k, the 4 tip GTC with EV is US$3k. Essentially $500 for the 2 additional tips & a 90 degree piece. Then we would have to have the bottom of the bumper re modelled to fit the 2 extra tips. Extra for shipping & fitting.
I heard both turbo back & cat back 4 tip systems. I like the cat back sound better than the turbo back sound (go figure), both with open valves. Sounds deep, throaty and LOUD.
Only thing is our BMW warranties with our new/relatively new cars, installing anything other than M-Performance at our dealers.
