Well the cheapest way is:

 

Modify a stock LGT or WRX exhaust manifold to mate to your stockmid pipe you would need these parts (that I happen to have laying in my dining room and want to whore the pics out :lol:):

Which yields this:

You can Heli-Arc (TIG) or MIG weld it with a 75/25 gas mix .030 wire amps set to 1/8" thick plate steel

 

IF you can weld this would cost you $150 TOTAL (parts only)

 

In not this will run you about $350

 

You could also do this (again my pic I want to whore out:)):

Would cost you about $225 in parts (header, catalytic converter, pipe, flanges)

 

About $75-$100 install IF they fit if not this must be done:

Then This

And add a short piece of pipe to bridge the gap.

 

 

YAY!

Sorry but I'm not sure I follow. If I buy an ebay header, all I need to do is have a shop cut the header as pictured above, have them weld a pipe to connect it again, bolt up and thats it?

If you buy the eBay header, you MIGHT have to cut it like i cut mine to fit your engine, THEN get a simple pipe bent to mate it to the stock catback and here is why :

This is how the Borla Header (eBay header) looks when bolted on the car before any changes. You see that the stock mid-pipe will not work. So what you do to make them work is remove the stock mid-pipe and have them make a pipe that connects the header flange (The end of the header ) to the stock cat-back exhaust like this:

You can leave the stock system on or get an aftermarket system as they will all bolt up no problem :)

OH! now I get it.

 

Any issues with 02 sensors? Sorry about all the questions (I bet they've been answered numerous times) but I though I might as well just ask. :)

 

Typically the cat you buy will have two bungs integrated and you can screw them into the bungs. You may have to extend the rear O2 but no other issues beside that.

Well now my Legacy rocks this setup (as of 6 weeks ago):

And I have to apologize to user roa I didn't buy the hogzaust hype so after my conversion my Legacy was as quiet if not more than it was with the stock manifold, due to the stock CBE and muffler. It sounded like a stock LGT, quiet. So i went down to Lowes got me 8 SS washers (3/8" dia) and put them in the mufflers. WOW! That sure did open her up :) but it was too loud, SO i took out one set from each muffler and only have one bolt with the washers in them and only ONE washer per side instead of two.

 

Let me tell you that was the ticket :) the smaller the gap the more tame and quiet it is yet still has the signature boxer rumble. No soot, corrosion, rust or anything.

Video/Audio clip please!

 

 

Yeah once I get home from the office today ill get one. I had to replace the mid-pipe to manifold gasket and it had a bad fire ring and produced a nasty "tick/hiss" which wasn't sexy :lol:
