They sound very nice, just a tad louder than my Magnaflows, I also don't have headers, I have my original manifolds.

 

if you would like icould try to get a sound clip of my exhaust up by the weekend

 

i'll try to record mine as well.

wow that sounds REALLY nice for having a baby cam in there. i wish i had a sound clip for you guys of mine with its lopey growl.... 40 series are just awsome for muscle cars

 

ok i have a video...the picture quality is really crappy and you cant see much but it sounds good enough that you get an idea for what it sounds like. it kinda sounds like there is some wind noise too so just ignore that lol.

not too shabby. i have y et to hear the hooker aero chambers, does anyone have those installed?

 

^it actually sounds a bit better in real life lol. i took the video with myold digital camera.

 

This is a little off subject, but can youpost a pic of your tach and tell me what kind it is. I'd like to check it out for my 65 GT. Thanks.

 

Should I take the glass packs off my 65' GT and redo the mufflers and pipes?

 

Yeah, tear those out and get you some Ravins 33 series. You can't pay for all the noise tickets you will get.
