A Must Have Exhaust for the F8x BMW !!
Let me start by saying this exhaust is amazing!! Everyone compliments my car now saying how it sounds like I'm driving a Formula One Car. The great thing about this exhaust is it isn't obnoxious for a cold start like it is stock(referring to that crazy rattle of a coldstart). It makes your car just have this "deep mean gurgle" to it. Im obsessed! Cant drive my car enough now. I will say my seats now vibrate a bit with this exhaust but I'm not complaining, and neither are my passengers ;) haha with the Valve control it certainly helps with make the car day and night while driving but be ready to clean those right side pipes a little more.
-Only reason I gave a 4 star on quality was because of the welding, Im from a family of welders so I was not 100% impressed with how it looked.. and some pieces weren't ground down so friends and myself that installed the exhaust kept getting cut. THIS REALY DOESNT MATTER its all under the car anyway- was just a personal note so you know I'm being honest.
