True dual with a 5.3

Postby fox4wd1981 [OP] » May 21 2011, 8:18am

Can anyone offer some input. I am wanting to do a true dual on my 08 but concerned that it may trip some sensors or turn on the check engine light. Any advice on this?

If you remove the catalytic converters, it will turn on the light. Also if your engine has active fuel management (V8-V4 mode), when it goes into that V4 mode, you will not like the droan sound.
