I like the Bronze, especially when it is a darker bronze. I went with Gunmetal on my Nitroyellow and loved it, but on the grey I would add some contrast
I have it, It is decent, the EOS one for 429 is much better, I have one of those as well waiting for when I damage this one, the rexspeed has a crack point that all of them will eventually crack at. Get the EOS when it goes back in stock, it is way cheaper and way better thicker quality carbon...
Yep all of Valve Masters exhaust are re branded Chinese made stuff from Ali Baba, some of the stuff of Ali baba is not bad, but you should know that it is just re branded and you can buy it way cheaper yourself, just have to wait a little.
I would make sure everything is tight as that can cause vibration, but my AWE does sim things in 8th gear, in sport mode the car does not really ever shift into 8th, but in normal mode it gets to 8th as fast as possible and just because of how deep and loud this exhaust is you get some vibration.
Best loud intake for the money is MST v2, In my opinion and I have heard both in person, it is louder then Armaspeed, if you are on a budget, CTS with the inlet pipe is mega loud. I have ran both, as well as AMS and BMS. MST overall winner, CTS behind, then HKS is the coolest by far
