How much louder are headers?
Assume you've already got a middlin-loud catback, in my case a Z06 Ti. How much louder would a set of longtube headers make the car?
Which would be louder, going to headers on the Ti cats, or keeping the stock manifolds and going to a louder catback, like B&B Bullets?
With headers, is there much volume difference between metal matrix cats and offroad pipes?

With the setup I have there isn't much difference at idle and regular driving isn't much louder. WOT is considerably louder and has a good rasp when the RPM's drop between shifts.
I have a buddy with the same header package as me but with bullets and it's way too loud for my likeing...

The Z06 Ti's are kinda loud with headers, but it's a different kind of loud....not annoyingly loud, like with a lot of aftermarket exhaust. With headers, the Ti's just sound....mean. It's a sound you just have to hear for yourself to appreciate it.

If you would like, you can check out our website. We are currently uploading video's of different exhaust setup's so you can compare...

Ti's are quiet with or without headers. The difference in volume will be minimal if you add headers.
Remove the cats and it's a whole new world of noise. But the Ti's will still kill most of the volume.

The car was louder than I expected after the headers. On the highway it was loud enough to be annoying so I installed the insulation in the rear half of the car. That made a huge difference and it no longer bothers me.

From the outside at idle the car is noticably louder, but it sounds good and is not so loud that it gets a lot of attention. Same from a drive by. That changes once you accellerate hard - it gets very loud and attracts a lot of attention (not all good).
Hope that helps.

I started with stock manifolds and a Ti cat back, 2-gutted pup cats and two factory cats- sounded better than stock but not noisy.
went to LG long tubes, random tech cats and the Ti-sounded better all around and much better at full throttle.
had a bad cat, pulled the cats and ran it without them for about 3 months-now this was by far the best sounding setup, idle and easy driving were acceptable, full throttle was mean, got good comments on sound.
i am back to RT cats, long tubes and Ti cat-back this should be acceptable sound level-probably quieter than B&B bullits without headers but raspy, no drone

The biggest impact on the exhaust volume on the C5 is what cat-back portion you have. Bullets with stock manifolds, will be louder than the TI's with headers.
Now that said..some cat-back exhaust like the Borla Stingers, Bullets, SLP Loudsmouths, will become insanley loud with Headers.
It's all in the cat-back
and to some degree if you run cats, or no cats.
Sound clips are fine, but keep in mind you are going to still have no idea how loud INSIDE the car is, which is what concerns most.
Try and listen to someone's car live. Lastly, when you are listening to a Sound Clip, or a live car for that matter..... pay CLOSE attention to what other Mods that car has,,,,, Superchargers, Cams, Heads etc. etc will significantly effect the way the car sounds.
I had SLP loudmouths with Longtube headers on my stock motor, PERFECT for me, loved it, then I added a Cam, and it changed the whole dynamic of the sound and I ened up switching the cat-back. The SLP's with the Cam made my car sound to raspy, almost like a Harley.
Good luck
Sorry for long post, but , Been there, done that, have the T-shirt.

I'd also like to add, what is TOO loud? What's just fine to a twenty-something with the base cranked up on hip-hop may be insanely loud to a fifty-something that is pretty happy with the sound of some GHL Magnums.
I agree. You need to listen in and out of a car equipped like you want or as close as possible to it. Find a large Corvette club nearby and go visit.
