I might be wrong, but aftermarket headers on their own only give you an increase at the top end?

The headers really only liven up the top end. They do nothing noticeable in the lower and mid ranges. That's right. It frees up the revs above 5500RPM according to the butt dyno.

Rear sway bar and new legacy suspensions (I have an outback)

RSB will help a whole lot. Well worth it.

I saw that I can get the Cusco for a good price from RHD Japan, but would be happy with the Ultraracing one as well.

Just depends on the deal I get when I buy it in a month or two.

Good to know for the CS discount.


Priced up Cusco too.

  1. It's 20mm vs 21mm
  2. About $40 more expensive, both delivered to my door.

According to RHD Japan the Cusco is 21mm too 9_9

You mean 40$ more expensive for Cusco ?

When I priced it on Pro Wholesale without discount it was more expensive than Cusco, both delivered.


We are shopping for different part numbers and in your case Cusco might be a more favorable option ;)

Mine currently sounds exactly like the car at 3.32


That's not bad :) Similar to stock sound but louder I guess.

Closer to $400 or $500 if you take a 21mm one with rear lower brace.

I didn't express myself correctly, I meant that you need to reinforce the rsb brackets if you take a thick RSB. I wouldn't install an RSB without reinforcement now that I know about this problem. Seems that some guys abroad even bent the RSB brackets with the stock RSB.


Ultraracing say that you need an underbody brace with bracket reinforcements when you install their RSB pointing you at their one. They're just trying to sell it like @GorGasmSpecB pointed.


Of course you can mix the brands :)

Another thing to note @delta  Make sure you get the right underbody brace. There's two different part numbers: one is for a plain underbody brace, another one is underbody brace with integrated rsb brackets. 


Yeah saw that, won't make the mistake, thx

Isn't it 20mm hollow on the japanese version and 17mm on the US version ?


GT and 3.0R RSB are not always the same.


Partsouq lists either 20451AG080 or 20451AG021 for the chassis number of my old 3.0, check what part number is for yours.

Was significantly smaller diameter compared to ZeroSports 21mm replacement.



20.0mm: 20451AG000/20451AG001
19.1mm: 20451AG030/20451AG031/20451AG090
19.0mm: 20451AG010
17.3mm: 20451AG020/20451AG021/20451AG080
15.9mm: 20451AG060/20451AG070

      Hi all,
      Vehicle is a 4th gen 2005 legacy sedan pre facelift.
      My brake light has stopped working on my rear left upper bulb. I switched out the bulb on the other side to test but no cigar. To me this indicates the wiring must contain the cause BUT the other lights on the same loom are working (lower brake light bulb, reverse bulb and indicator bulb). Has anyone come across this before?
      Any advice appreciated, thanks!

      Hey Team,
      Have any of you had to replace an in tank fuel pump on a gen 4 3.0r Legacy? Looking around found that GOSS do a replacement pump for a good price, but different sources say to use one of two models (GE271 or GE272). Has anyone gone through this process? What brand did you use, who stocked it etc any info would be a great help.
