Hey Guys, I just bought a new 2018 BMW 640I AWD GT with Auto Trans. I was considering dumping my stock exhaust to get Dinan's performance exhaust. I think the MSRP is $2800. My question to you guys is:

1. Will it void my warranty?

2. Any issues or problems? i.e., leaks, engine issues after install etc.???

3. Will I lose any low end power?

4. Will it effect my resale value?

Can anybody also show me links to reviews for this. If anybody has first hand experience would love to hear from you
