r/AudiA5

I have a 2013 Audi A5 B8.5 and was wondering if I should get a straight pipe or not. Tbh dont really know what it would sound like and if it would be better to be smelling 2 cut mufflers and one res or vice versa stench wise. Or should I go with an exhaust system (which would be alot more expensive than a straight pipe) with basically the same results. Lmk!

I've been using Castrol Edge 5w40 on my 2.0T A5 for the past 2 years, however since my local shops have ran out of it I'm thinking of going for either LiquiMoly Leichtlauf High Tech 5w40 or LM Synthoil High Tech. Is anyone in here a long time LiquiMoly user and if so how has the experience been so far?
