I have the Pacesetter Header and I have done so much to make it work....it doesn't look anything like it did originally. First I had to saw off a bit of the front of the flange to clear the water outlet under the dizzy, I then had the slip flange welded together, then where the pipes turn from 2-1 to extend to the cat I cut it and had a flange welded on it and had a custom pipe with a hi-flow cat welded and flanged to mate with the rest of the exhaust system. I had to bore the stud holes for the head flange since it wouldn't slide easily, finally I had an o2 flange welded on ( since the one provided was too far back and I used it for my secondary o2, california emission vehicle.) right where it turns from 2-1. Off to Jett Hot for coating they went and finally on the car. I paid 100 bucks for the headers and over 400 to prep em! I also have the 2.5" Pacesetter exhaust system and together it sounds weird full throttle...kinda like a swooosh rather than a roar, not annoying though.
pacesetter manifold with powerwrap !

Supramacist: Yes it flows better than stock, for me anyways because I was California Emissions, the header eliminated my first cat and the high flow replaced the second cat. I dynoed the car shortly after for a gain of about 14HP and about 15TQ.....this also included a custom cold air intake. and at the time the o2's were not connected so the car was literally spitting out fuel....about 8or9:1 AF.
From what i hear, they are very quite, and bacically a stock replacment, with more flow 
Great for old people who hate loud exhaust :rofl:

I also have a set of pacesetter headers. I had it modified to a 2.5 and dumped the y that came with it. Also had the oxygen sensor piece welded flat to the pipe so the sensor would be in the exhaust stream more and not masked.
The shop had to modify the flange for it to mate to the head, the holes didn't line up and the flange had to be ground a little caise it wasn't a flat fit. I also wrapped them down to the Y. I wasn't happy that the pipes are so close together. I couldn't wrap all the pipes individually all the way down to the collectors.
If I would have researched them a little better before buying I would have gone with the OBX and gone stainless. I will probably buy a set on my next vacation the the USA and bring them back here and do this again.
