Default custom header

is it possible to have a custom header built?

It seems it would not be too hard to make a header where both sides are equel, and by removing the first cat, and making a custom pipe it would be a really easy bolt on.

Any ideas?

Of course it's possible to have a custom header built.

If you want, you can have a custom CAR built..... That's what "custom" means...

Search for pictures of the MRT exhaust for the GC8 and take those to a competent exhaust shop (not Midas, etc.) and have them make you a system like that. It's basically what you describe.

Before the Brullen/Revolution threads began, I looked for an
alternative to the dubious Borla. I sent emails to a couple,
S7S pops into my head, and basically got nowhere with it. My
guess is that in the long run it won't be worth it unless you have
something really out of the ordinary in mind.

I am sure you have seen the Brullen and Revolution threads
already, and I think there was a rumour of a Greddy development
going (although it might have been for the WRX). The feedback
from the Brullen installs has been positive, and that's the route
I am going. The Revolution will be less expensive but it doesn't
include the high flow cat.

Happy hunting.

Sorry, that was S&S not S7S. Not that it really matters, because
they weren't able to help anyways.

Unhappy OW!...

Custom headers start at $1500.00 for the Subaru. 321 Stainless steel(this makes it capable to support turbo systems) is used along with a very nice merged collector. The quality would be top notch.

If you are looking for something cheap, I believe that BORLA makes a header for $450.00. I can't remember if it was equal length though. The material is not as good as the 321 but is ok for none turbo use.

peter
and i thought 400 was a lot...

Thnx

You didn't say you were trying to save money. Headers for a boxer engine are not like a cat back exhaust. You can't just bend a pipe a couple times and weld on a can and a flange. A good collector will cost almost as much as a whole cat back exhaust, believe it or not. 321 stainless also costs a lot more than 304, but you get what you pay for in durability (resistance to head problems and rust).

Sure, I made a crossover pipe (heads to turbo) for a 85-90 Subaru Turbo in my Garage. I also have made a Y-pipe (header) for my 85 brat in the driveway. The tools needed are simple too.

Welder
hacksaw
angle grinder

Everything else is just nice.

If you wish to do it yourself, feel free to email me about it.

You made a 4-2-1 or 4-1, equal length, slip jointed, 321 stainless header?

Eh, no Stainess is flat stupid around here as you have to WORK to get stuff to rust. Anyway I still don't get why people spend the extra money to get stainless, when most of the time the shops don't even know how to weld it correctly.

Slip joints are nice, and I'm sure they are easy to do if one cares about them. For the crossover there is NO real possiblity of doing so, as the one place you have the room to do it is right next to the oil pump, oil filter, and a bunch of wires. Not a good place to have any exaust leak during warm up. Equal length is also unlikely in this case due to the very limited room. The pipe merge is by far the hardest part of this one. I'll find pics to show how tight it is.

As far as the equal length, I'd have to measue on the Brat but its as close as a 5hr under the car job can be. Biggest problem is that the crossmember and swaybar have only one place for the exaust to run w/o killing ground clearence which is more important than 1/2-1" difference in lengths. The merge is easy to make in this case as I just wipped one out of some scrap pipe using a chop saw to get the angle cut.

Are you saying that someone can pay you for 5hrs of work to build them a header? How about an XT6 header? So what do you say? *hands in prayer*

It has nothing to do with rust and everything to do with heat tolerance. If the shop doesn't know how to weld stainless, find one that does (like Cascade). If you want a cheap header, you have lots of options, but you get what you pay for.

Kevin, I haven't cut the heat shields off of the XT6 header yet to see how bad the 2-1 section is on each side. It is however fairly easy to chop the pipe off at the end of the 2-1 section and then build a Y-pipe section onto it. If you do it from there back it shoudl be fairly cheap, although its been a LONG time since I've looked under a XT6, so it might be more difficult that it is with the wagon.

Here is a quick pic of what I did on the brat. Its only a temp one, as I need to ditch the busted air injection system, then make a whole new system from the heads back. I'd atleast grind the welds flat, and possibly paint it with silver 1500 degree paint for a "finished" exaust.

I was in the same boat you guys were in. It takes more than just a little wrangling underneath the car to make things work the way they were intended to..

The result of about 6 months workand thousands of miles of testing and 4 design changes....



Good Luck...

Oh BTW... Brullen sells these complete with a High Flow Cat for $1129.00 Canadian (that's about $730.00 USD)

Not meant as spam... Just know how you guys feel...

I was making a general statement to anyone that is intent on making their own custom header. It was a long hard road to make long equal length primaries fit underneath a scooby.

Twas a pain, but well worth it..

In other words, been there, done that got the T-shirt.
