Need good feedback on both of these and what should I do? I won't be doing this myself I will for sure take this to a german focused shop. another thing... I DONT WANT TO VOID WARRANTY. I am also seeing that since muffler and resonator is behind the cats, it WON'T void. Thoughts on all this?
Thank you in advance!

This will definitely void warranty if you have car trouble that was deemed to have been caused your mod. I would suggest you just get the M Performance Exhaust and call it a day. Since it's a BMW part shouldn't void your warranty, and there won't be drone like you'd get with a resonator delete.
