I'm getting a high-pitched clicking sound out of my exhaust when cold, when accelerating. Once warm the sound disappears. I recently installed a Roush Stage I Supercharger with Brenspeed tune, but can't imagine how/why that would cause the sound that literally just showed up today. Any ideas?

 

Your exhaust gaskets may need to be replaced.

 

I once had a exhaust leak, not sure about the high-pitch noise but the clicking - it sounded like a 'bicycle chain' rolling. I'd check the connecting junction (from OTA pipes to axleback) are put on snug. Post some pics, liking your stripes!

 

any news op?
