Understood, thank you for the info. I can handle a little drone as my other car is an F80 with a remus catback that i drive with valves fully open 80% of the time. I'm also fairly young at 25 so that helps.

I definitely like loud. Half the reason I got a roadster is so I can row gears and listen to the exhaust scream with the top down. I realllly love that throaty sound the headers give and am thinking there might not be any other way to achieve it. However I don't want to have to put a cat on every time inspection comes around is there a common solution? a specific cat(thats guaranteed to pass) that everyone uses on section 1 after relocating the O2 sensors? But maybe that'll will tone down the mean throaty sound im going for. I've read about so many different setups im starting to get confused lol

In the meantime I'm taking the mufflers off tonight to see how it sounds and hoping theres less ricey rasp then the youtube vids make it seem like there is
