I have not had the remap on my 2020 Roadster - I don’t think I need it - but fitting a Librands sports exhaust was a must for me. It just adds such a charismatic exhaust note. I’m sure it’s improved the bhp as well, but I’ve never had it on a rolling road to check.
Just as well David as there isn't one currently available. One was developed by MMC but discontinued several years ago. Cain of Wolf Performance in the UK is hoping to offer one soon to cure rev hang although in my case I'm now convinced it's mainly due to dual mass flywheel.
I have the factory side exit pipes/silencers fitted which should add modest bhp but they really need to be coupled with sports CATS which are not cheap.
