Has anyone gotten the AMS STX 400?
I bought a 2010 MR two months ago That was modified Going through the mods it's pretty much the STX 400 kit Minus the cobb, I don't know if the car was tuned with the cobb And the previous owner just kept it, Or he tuned using open-source I am now saving up for the cobb. As far as As all the parts that are there they are Quality pieces, The exhaust has a beautiful deep tone he did get a resonated test pipe rather than the straight test pipe, And everything seems to fit up really nice.
