Stephen, did you look at hndaeater's(i think that's how you say it) dyno comparison of the header's. I don't know what the difference between your results and his would be because i think your running more boost and his is a 00-01. Would there be much of a difference?

Yes, I saw his dyno. He's making about 30 more peak hp, but the gains are restricted to a pretty narrow rpm band. I'm seeing gains beginning at 3500 rpm by what my datalogged runs are showing:

Yep that is what i noticed as well, the torque does seem to have a +10 advandtage over the y pipe starting at around 3500 rpm. So the question remains, was it worth it? I just don't understand how the dyno doesn't show a bigger gain. After looking at several 1/4 mile times of ypipes vs. headers it seems the headers are far superior

Also did you buy the headers for the sound or performance. I ask because i am on the verge of buying these things and just want to make sure i know what i am getting into.

That being said, the Cattman headers really do increase the sound level of the Apexi catback a bit too much to suit me. But that's just me (i.e. older and more conservative than most people here). I'm now thinking of trying the 5th gen muffler.

Both, really. I was just as interested in the sound improvement as the performance. For all out performance, Warpspeed's 3" exhaust is probably better, but I didn't want the loudness.

Sounds like your in the same boat as me. i want the performance gains of a 3" exhaust but not the sound. Also i have the 5th gen muffler on and it was a deff improvement of the sound level over the aftermarket muffler i had. I noticed that warpspeed doesn't make the 3" exhast for the 5th gen. Would it be hard to custom make one. I know alot of shops around here say they can't do 3" mandrel bent.

StephenMax - Do NOT get the 5th gen muffler. Get a 60-series Flowmaster.
SM and Chris - Have you guys considered an ATP VES?

Whooaa, i have never seen that. Is this a proven product and company or is this one of those ebay type gimmick products

ATP is one of Garretts' exclusive distributors and makes nice albeit expensive parts.
I'd rather have a quiet somewhat restrictive 2.5" exhaust 90% of the time and the VES or e-cutout for that other 10% vs. a 3" full exhaust.

So from what i conclude this will give me about the same gains as a 3" exhaust. If so i am all over this like a fat kid on choclate cake

Basically, I'd have this installed on a custom 3"-->2.5" straight pipe to replace the cat with a Hallman $50 manual BC on the vacuum line from the engine bay through the shift console to the VES actuator.
That way I could adjust when it opens pretty easily.

In theory, better then a 3", since you don't have such a long length of 3" piping and bends to go around/over the rear axle or a muffler in the way of flow.

Why cattman of course. OOOO $hit here we go again. Just when i think i am done the bug bites me right in the a$$ again

I am considering doing this when I slap my S/C on....kinda deciding between this and keeping my WSP mandrel Y and just throwing a cut-out on there....right now my exhaust is very quiet....I have the new prototype super quiet muffler that WSP sells....kinda wanna keep it that way....but would like my car to sound better inside, just not louder...any ideas...would cattman headers do that?
on another note, hnda etr's dyno of the stillen y pipe and then the cattman headers was very impressive to say the least, he had a 20whp peak gain or so...and that was with the stillen y pipe to begin with...
I agree with stephen 100%....I have not seen a dyno yet that proves the headers are worth 3-4 times what y pipes cost....not to mention the labor is a lot more intensive....on NA maximas that is....on boosted maximas, things start to get really interesting and the headers really start to shine/merit their cost!!!

Yeah his peak numbers are impressive, but look at the rpm range it is over. Also i think the stealin y pipe has actually been dynoed to show very slight gains over stock. I'm not downing the headers because hell i plan on getting them because i am trying to maximize my exhaust setup. Just trying to help imform you so your not dissapointed in the end

Can you ellaborate on this alittle bit, i'm not sure i quite follow you here. Right now i have a test pipe. What is the Hallman manual BC

haha hang on to it i'll probably need it.
BTW how did you hear about this thing and why aren't more people running this?

check out the exhaust cut out that you can activate with a switch and not by boost. That way you can choose when it comes on. I would think that is the bettter one.
I am going for the headers!
maybe exhaust cutout on that ...

I'd rather have the electric controlled cutout. That way I could open it or keep it closed whenever I want, rather than it opening each and every time I make boost.
http://www.quicktimeperformance.com/QTEC/
I started my engine after installing the headers but before connecting them to the rest of the exhaust. It was so loud when it first started it sounded like an explosion. I don't think I would ever use a cutout except at the track, and I don't go to the track (too far away).
What would be interesting, though, is to have a dual exhaust setup with all the exhaust going either to one muffler or the other. The cutout would control which muffler the exhaust goes to. Then you could have a quiet muffler for daily driving and a flow-through muffler for performance. Might look a little funky with two different style mufflers though.

Electrical parts in contact with extreme temps and road debris/water is never a good mix, however the eCutout is still a good reliable option.
I just prefer the automatic feature of the VES and being able to control at what PSI you want it to open. So, daily I'd have it set to only open above 4psi or so.
Another thing to consider is that you have a SC vs. a TC. SC is going to be VERY very loud with the cutout open, where as the turbo absorbs/reflects much of the exhaust noise. You might try dropping your straight pipe and drive around a bit to get a feel for your new Maxharley.
It will definitely turn heads when it's open. Hopefully, it's not the wrong heads.

Running the Cattman headers on my 2K2 is still awesome, even though I'm NA (for now...) I would definitely buy them again... Michael, you can check out my car anytime... even though you never did return my phone call...

It's not different then a mechanical waste-gate.
You can adjust what PSI it opens via spring or boost controller/bleed valve.

After listening to that video on the website of the VW 1.8T it sounded pretty good. I know it will sound different on mine, but i don't think it will sound bad
