I think i'm circling around some mix of delete my muffler and cats (but not the resonator) for a louder exhaust note.
Anyone have any thoughts here on both the Pros and Cons on potential mechanical issues as well as the exhaust note?
Socially, I'm not worried about noise violations/tickets or not having catalytic converters on.
Also any recommendations on parts to do this?
Apparently, one issue is the maintenance of back pressure to prevent engine damage? Does the resonator exclusively do this? I don't to risk engine damage in anyway.
Here are my initial thoughts but please chime in?
-muffler delete - no mechanical issues and possibly some slight gains in horse power? And deleting the muffler will generate the largest gains in a louder exhaust note?
-cat delete will cause the engine light to go on, not harm the engine but may cause some loss in power?
-resonator - removes back pressure and can damage the engine?
-resonator delete - i shouldn't do this as removing the resonator will impact back pressure as well as power / torque possibly affecting performance and causing engine damage?
