Sorry to hear about your experience with the inserts.
I have hooker side pipes on my vette as well. The 4" pipe with the insert inside it should not be welded to the headers. This is why your mechanic says it would be a big job now. He created that situation.
I would recommend the STS baffels if you are looking at buying something else.

I run these and they have a very authoritative sound without being overwhelming.
My guess on what spraying water into a hot glass pack does is that it cools the packing fast enough to either fracture it or make it brittle. Then next time you drive it much of the packing is able to pass out the exhaust since it now is broken into smaller pieces that can fit out the little holes in the pipe that normally retains the packing.

Do a search on Youtube for "corvette sidepipes" or "hooker sidepipes" to hear what others with different inserts sound like.
Hooker makes 3 types of inserts;
Reverese Flow - the most restrictive, quiet
Glasspack - medium level (what you currently have)
Maximum Flow - high performance, loud (the ones I'm using)
STS and SweetThunder are another brand as mentioned, also Vettepack but I think they are not as loud.
The STS type looks like a pipe with a corkscrew around it. The pipe part is capped, and the cap can be drilled or removed for increased sound and performance.

I talked to my mechanic, and ask what he had welded. It was exactly what Flyeri talked about in his reply to me. He welded two studs to the frame that hold the pipes and I ask why would he have to take the headers off to take the baffle out. Apparently, there was a lack of communication, or I just misunderstood. He said he would loosen the bolts on the headers as a precaution, he wouldn't want to put any bind on anything that might cause the Crome to crack. He said it wouldn't take him long. I feel so much better about it now. All is well
No worries ��

Thank you so much for telling me to get the old inserts back. That would have never crossed my mind.

Someone told me that I could have my glass pack blown out, wouldn't the end result be the same concept as the water hose method?
I have been listening the different baffles on the net. I feel like a kid in a candy store. It's great to have choices, I just want to be sure I am happy with the one I chose.

Removing the packing will create a louder but also harsher sound. Over time the glass is broken and some escapes making it louder. It also becomes compacted by the pressure waves reducing it's ability to deaden the sound.
On dirt bikes it's regular maintenance to replace this glass packing once it starts to get too loud.
Have you had the alternator checked yet for that battery light issue?

Sounds like it to me. A glass pack is a straight through pipe with many small holes drilled into the pipe then wrapped with a packing (fiberglass) then that is all encased in a larger pipe. The sound goes in these small holes on it's way through and is baffled by the glass packing.
