Asking for a friend -- 2020 RR SVR. I know very little about LRs (I drive a TrackHawk). Looking to get a little more grunt out of the exhaust (which already sounds pretty dammed good imho) and lay the groundwork for future upgrades... on a trackhawk, it's easy, go to corsa, magnaflow, american stainless, pick out the cat back you like, grab some headers, throw on a pully, tune, and you're done. Spent some time researching, seems these types of upgrades aren't as common for the RR but I'm sure they're out there. What are the common exhaust/header combos the RR crowd is using? While I'm at it, what are some common upgrade paths? U.S. vehicle.
Thanks.
