Side exhaust muffler inserts?
I recently purchased a c3 that the original owner had put headers on it and removed the mufflers replacing them with glasspacks. Got it running the first time today and it’s quite loud and raspy (I’m ok with that in cars but when it’s struggling to get 200 hp I think it’s too loud). In the far future I intend to put side exhausts on it and am looking into muffler inserts for them. If anyone else has some side exhausts with Doug’s headers d952 or d950 inserts (or any inserts really, just tell the manufacturer and such) I’d greatly appreciate it if they could put a vid in the replies so that I can see how they sound because I am struggling to find a video.

Here is a thread about the D950 inserts versus other ones. I have the D950s myself and am quite happy with them. The baffles do flow a little better I hear at the cost of being louder, but with only 350 horsepower in my car it’s not much of a restriction. Here’s the video that goes along with it.
