Well, it's done...

I finally installed my headers I had been waiting on with the help of billboost (one of the admins over at nebonnevilleclub.com).

I had purchased a set of the used XS Headers which were being sold on ebay a while back from a member on club gp. These are the headers that were crafted after the SLP setup, and all I can say is that they are nearly identical minus the coating. Bill currently has a friends set of SLP headers sitting at his house which we used to compare.

Size of the primaries and pipe bends are identical. Flanges are welded in the exact same manor (welded on the inside of the primary with a tack weld on the outside). Both headers had a significant amount of weld slag on the inside of the primaries and near the egr tube. (slps had more in some areas and the xs had more in others). The cross over pipes use the same slip on design, and both systems put the 02 sensor in the same location requiring an extension harness.

All and all, I would take the XS over the SLPs any day of the week. I picked up my set used for 275 shipped. A set of SLPs run for between 450-650 USED!. I dont know about you guys, but I am all set with paying an additional 175-375 for cermaic coating since essentially both sets of headers will function the same.

I will try and post up some pictures of the headers installed, and a sound clip of the 3" exhaust, headers and lack of cat...

 

Nice job pricing things out and coming out ahead! What type of coating did you get on them? I did a flat black ceramic coating on my nickel TOGs, and I'm happy with it.

 

honestly i didnt bother worrying about coating. My iat and coolant temps are low enough where i couldnt really justify paying for a 200.00 coating job. they are just straight up stainless steel.

 

 

very nice. amazing deal you got there.

 

Very nice!

 

 

Space, install was a little bit of a pain, but not too bad. I couldnt imagine having to do it on the ground like a lot of the hardcore DIY guys, but luckily I have a lift. The front and cross-over were cake, its the rear that is a pain. You have to roll the motor all the way forward so its practically touching the radiator to slide the rear manifold in and on the studs (or you can actually remove the studs with a 5.5mm for an aditional inch or two of clearance).

As far as increase in power, its only a tiny bit noticeable out of the box, but once i started playing with the HP tuner and adding some more timing since i was knock free, the car really came to life.

Track opens up on april 12th, we will see where i land.

All I know is that I beat up on my best friends Mazdaspeed 6 (turbo awd), which ran a 13.8 bone stock. I pull his car on the street all day long whether its from a dig or a roll.

Im shooting for 13.6 on a 3.4 and race gas on the 12th!

I picked up my SLP's for $600 and had to do a messload of work to install them. This kit you have is a much nicer design.
