Code No. 33005-AT004
●LEXUS IS-F Metal Catalyzer
Two 2nd catalyzer and silencers are mounted in the stock Center Pipe which is 60% of the entire stock exhaust system layout. Stock catalyzer has 600cpsi but we changed it to 150cpsi. This change provides awesome purification and less exhaust pressure which will leads to more power. By reducing the exhaust pressure you will have bigger sound from muffler but we made the silencer bigger to control the sound. Now other people would not even notice the change of the parts!
