What problems could the Catless dps cause?
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
