Hi guys, I'm thinking of doing a resonator and muffler delete on my 2018 Accord and I was wondering if anyone knew it would harm my engine in any way? Since the resonator can be used for back pressure, I know that my gas mileage might go down but I searched online to see if doing a res delete could harm the engine and didn't really find anyone talking about that. And since each car is specific, I just wanted to see if you guys knew anything. Thank you!!
