Ben Evans New Member 8 Member For: 5y 7d Posted 21/11/19 06:41 AM Share Posted 21/11/19 06:41 AM Hey all about to get a whole heap of mods done to my T and am debating between hollowing out my original cat or replacing it with a hi-flow. I live in Tasmania so do not have to worry about emissions or anything. I want a bit more noise from my car and was wondering if hollowing it out would be the way to go.

A decent quality cat wont restrict power Link to comment Share on other sites More sharing options...

Sure the odds of getting pinged are minimal, but is it worth the risk? Edited 24/11/19 10:17 PM by G6EEEETTTT Link to comment Share on other sites More sharing options...
