Question about converter.

2003 Views 9 Replies 4 Participants Last post by  TrevorS
I want to switch out my factory cal converter and replace it with one from magnaflow. Will this help my borla exhaust sound better and louder and which ones can I choose from. The magnaflow website was kind of confusing.

I'm trying to figure out which will be smarter. Do I get a different converter and the weapon R s-pipe or just get the weapon header and s-pipe combo.
Would switching out the headers and keeping the cat still make me pass emissions? I live in IL.
Nvm, apparently the XB has two cats, one on the header and then the one underneath the car.
