I had a 2010 ls460l awd black on black for 10yrs....engine died so I got an s63 amg for a couple years and just recently went back to another ls460l....just a newer year. Just switched the wheels to black, then saw your vids....thinking about the straight pipe b/c it makes it sound more like my amg and doing the yellow or red caliper paint. One thing I noticed you haven't done yet is the grill. On my 2010, I bought on ebay the sport black version grill and swapped it out from the chrome...looked awesome. For some reason on my newer 2015, the fittings are different so you can't easily swap the two so I just took the front apart and painted the grill and bumper in between the hour glass to gloss black. Looks really good. There are some good pics on lexus forum too.
