surfer.vr6 0 Posted June 30, 2004 Just one question.... will taking out the contents of the cat, leaving just a empty shell increase the power of the car? Quote Share this post Link to post Share on other sites
16VG60 1 Posted July 1, 2004 It will remove the obstruction, such as it is, presented by the cat matrix. Unfortunately however the empty can that is left behind will not do much by way of improvement to exhaust flow and increasing power not to mention resonance. The proper way to do things here is to fit either a cat by-pass or a sports cat. Are you thinking of just altering / changing the cat on it's own or are you also going to change the system? There are nominal gains to be had from restricting your efforts to just the cat. The real improvement worthy of your effort would be found in changing the system and cat as a package. Should you require further improvement then the manifold and front pipe can be gasflowed and changed for higher flow items respectively. I think i have offered you a quote regarding a system and cat by-pass, please give me a call if i can offer any further assistance. Quote Share this post Link to post Share on other sites
