This thing is the shiz.
Different size "balloons" to seal off exhaust, intake ducts, etc.
Works great for finding induction and exhaust system leaks.
For once, a GM special tool that actually works...

I have to be 100% sure my ol ferd has no exhaust leaks before I install the Holley Sniper. The o2 sensor will lie to the pcm if it has any. I plan on using my shop vac discharge plumbed up to the exhaust pipe.....
Thoughts?
