The hi-flo cat does make the exhaust louder. It also helps improve flow and takes a little weight off the car

Ok thanks! What type of Cat should i get?? I cant spend too much cuz im spending $4000 on just the engine plus i need new tires and exhaust system. Should i get a Dynomax Cat since i am getting a 3" Dynomax Cat Back Exhaust (super turbo). How much do they normally cost. Thanks again! :hail:
