Okay, I recently picked up a 2014 M6 Gran Coupe with the Competition package. I told myself I was going to leave it alone but... well... its me.... and I can't leave anything alone.

So... my buddy had an M5 that sounded really good. He had tune, MSR Intake, catless DPs and eisenmann race exhaust. He was also pushing around 700hp

Im not looking for a ton of power, Im looking for more sound. MSR intake sound was amazing with the DPs. This was a few years ago and I see a lot of options out there.

Is MSR worth the money or is there comparable versions that will do the same for less money. BMS is similar style for less but I don't know much about them.

Similar question about catless DPs.... I see DPs for $300 all the way up to $2000. I can't imagine there is a huge difference between them all since fitment is pretty specific. Is there a good set for a reasonable price out there.

With DPs I would need a tune also right? to remove the O2 fault code right?

As for exhaust... if I do change out the exhaust, who has the best exotic sounding set up. I don't want an obnoxiously loud and raspy sound.... hell.... maybe I do. haha.

Well.... then you all for any info you can provide. Im looking forward to getting back into BMW life and contributing to the forum.
