S/S replaced mine N/C with the new design baffle & so far they are good while cruising & quite loud when on the pedal hard, just the way they should be.
If the bore scope has a 90deg. mirror attachment like mine, you will be able to look right into the holes in the baffle for packing. My Snap On scope is long enough to check all the way from the turnout to past the front baffle on my pipes.

Thanks for the suggestions, I don't think it is the packing though because they were loud as hell the day I put them on. I have another set of pipes that have mufflers inside with a cone on the front face, they are fiberglass
and have a 2" ID. These are noticeably quieter than the stainless units
but are still pretty loud. I hadn't thought about removing these old mufflers and installing something else that would baffle the sound but it sounds like a good idea. The units on the car are a completely welded assembly but my old units look like they could be modified with a new insert. The mufflers from Flowmaster are also 1 piece units that I would need to weld a turn out on as well as mounting tab and a retaining tab to hold it to the collector. They sell for about $200 per side not including welding on the extra parts.
I need this thing to be no louder than a modded Z06 or Viper under heavy throttle but I am not sure if that will be possible.
