How’s oppo feel about Subaru rumble? I’ve hated it for a long time because it sounds like a misfire (and as Clarkson says, it usually heralds the imminent arrival of a moron) , but I finally relented and added a UEL header to my FR-S. Can’t explain why, but on the FA20 the unequal length offerings just perform better. Gotta say, after driving her around for a few weeks I kind of like it now...
