Default Straight pipes

I just bought an 05 with the mufflers cut out (straight pipes right to the tail pipes). It sounds like a track car, but won't pass state inspection. I picked up some take-off C6 mufflers with axle pipes to put on. Question: What are the hose fitting tubes coming off the mufflers for?

Sounds like you got yourself the valved mufflers. They are vacuum controlled to switch back and forth from straight pipe to muffled.

The mufflers are off a 2008. Did they have the valved mufflers then? I wondered if the tubes were for some kind of 02 sensor or something?

Came out in 08 models. Look in one of the tail pipes should have a butterfly valve. One in each. With them open they're loud, closed they are quiet.

Thanks for taking time to share you knowledge with me on this. I'll check it out and figure out how to hook it up.

Since you don't have the 08 model with the factory connections you should look into B&B's vacuum module they use for their systems. It's fairly simple to hook up. Costs around 200 too. I got it on my car with their Fusion system.

Thanks for the info on that. When I recover from buying the car I'll look into it. For right now I'm just going to have the mufflers put on so I can drive it.
