I am well happy. I don't find it too loud at all. Don't think I would of been happy with OEM mod only. Below 3k its very civilised still.

I guess BMW are too good at making it so quiet and capable, discreet at the same time. But I want it to be a bit mental (maybe even scary sounding?) when I put my foot down. Just didn't' sound like a V8/420hp was in there before.

PM on the way...

I don't know. Seem to remember 2.5" or something. Not 100% sure though.

For me with the x-pipe....it's to raspy...
I think you have a lot of drone in your car at low rpm's ???
But that is just me...it's a very personal thing here...(sound )

It is very raspy above 3000rpm and screams like Gods private is trapped in a paper shredder.

Not much drone cruising in top gear 60-70mph. Its very normal. Only a bit more throaty when driving off gently compared to standard.

But I'm trying to cure the rasp... add resonator after x section or H section like akrapovic?

You still thinking bout swapping out to a new exhaust?

I need to pull my finger out get those EAS 80mm tips and have the OEM mod done at the same time!

Too late, just back from the swap!!!

New exhaust on!! I'm knackered, dirty, excited, underwhelmed?! I don't know.
Need time to try to adjust.

Completely different now!!

AAAAHHHH!!!
