With it removed, you will get to experience a low-pitched, louder, and a more distinctive exhaust sound..

Does removing catalytic converter affect engine?

Removal of catalytic converters from cars allows exhaust gases to exit their engines much faster and at higher levels. o Since catalytic converter removal allows for exhaust gases to exit a car’s engine at increased speeds, engine back-pressure is reduced, which lessens engine strain.

Do high flow cats make car louder?

Yes, high flow cats are less restrictive than stock and will allow more sound to pass through your exhaust system. I don’t know how much louder it is with stock manifolds though. Maybe you could put in jba or bbk shorties at the same time.
