I have to take them out for every warranty service right?
Could they cause excessive damage on a long road trip? 1k miles non stop?
Thank you guys so much for your time and patience. I just want to protect my car and use the warranty to my advantage while increasing sound and hp
No chance of damage from a set of DPs. As another said, it's actually the opposite (they are good for your turbos)... That said, they are not good for warranty service. I'm not sure what others do, but I would hesitate to take my car in with DPs if I were on warranty. They'll probably never know, but better safe than sorry.
