To my knowledge, and I've looked a TON, there's only one other video of that kind of setup.
I assume you're talking about third video that I threw on Youtube a while back, right? By the way, I noticed that my description of #2 was wrong and corrected it. In that one, my car has the catless connectors that come with the standard OBX 1-7/8" header package.

The problem with stainless steel headers is that they let a lot of high-frequency engine noise out that the OEM cast iron manifold doesn't. Doing a header swap alone basically increases "bad sound" only. Once you get an aftermarket catback, most of that sound will be drowned out, but if you stand in front of the car, you'll still hear it.

Yes, I was referring to that clip of yours. BudRacing just put up a video of headers with stock catback, and it sounds pretty badass to my ear. Sounds a little throatier. I guess I will see for myself what it's like in real life soon enough.

Different camera, different microphone, slightly different sound.

Wrapping them helps slightly, but I still hear a bit of what you're talking about. I would imagine that if the stock resonator was still there it would take care of the higher frequency noises.

there's no bolts in the block for the headers, and tightening spark plugs takes about the same amount of time as not tightening them.

if someone asked me to help them put headers on their V, i'd likely do it for free.

Wrapping them shouldn't help at all. You need sheer mass to deaden airborne noise.

Having catalytic converters takes care of most of the junk coming out the back end (both chemically and aurally--I just realized).

I'd help anyone on this forum with anything, to be honest. It'd be nice to sit down and shoot the sh*t with someone else and get some perspective on all of the work that I've been doing. I've only seen two other CTS-V's around here. One was just in passing, and the other one is owned by a guy that works at the same company I do. His V is a travesty--it's missing body panels and looks like crap.

I think the one thing that other V owners would likely comment on is how quiet the interior of my CTS-V is, given the fact that you can barely breathe standing behind the car. I've been hunting squeaks and rattles seemingly forever, and spent 12-16 hours (and $600) applying an actual soundproofing treatment (damper + MLV) where it counts. Unfortunately, that treatment weighs about 45 lbs, all told.

I would too, for the most part. There's a few ********* I'd leave hanging, but by and large, if anyone needed help with anything, and I had the time, I'd absolutely do everything I could to get them moving.

The headers are held in by bolts .. To the head sorry for to mis type and if your not careful u can crack a plug so it has nothing to do with how tight they are. And that price is for me to put them on at my shop .. If you want help I can do what I can but it costs money for lift time and electric and I don't own the shop it's my buddy's personal shop for his toys

Yeah, but the part that bugs me about that one guy is that he doesn't give a crap. The first generation CTS-V was a great first effort by Cadillac, and if treated right, can be both flashy and an intimidating performer.

I'm talking about 98cobra. I'd absolutely help the person you're referring to

Slightly off topic, but is there anyone within a few hours from Goshen KY that would like to help a college student on a budget with a header install? Some of you guys sound generous, and id like to have my hands on the install, but dont have a lift yet, nor the tools. I have a guy here that can install them and wish I could take it to him, but like I said, Im a college student for the next 6 months. Need to prep the car for a cam!
