Yas: Xforce does the
TBE for your RA. It is similar to the EvoX look, just exhaust mountings differ slightly. Overall look is the same. Go to:
http://www.perth-wrx.com/vb/evolutio...ystems-12.html
It will look like the Evo X below:
Guys: Xforce only does the equal length headers. This is version 3 that Xforce has developed over the years with no expansion bands like the earlier versions. Quality has been vastly improved, with more tolerance against heat cracks. These headers fit all the 2.0 and 2.5, without having to chg the oil sump compared to other brands.
A lot of people are concerned with the loss of boxer noise. These headers do reduce the boxer noise but not entirely.
Heat wrapping is the norm and will set you guys back $150.
Equal length headers provide less restriction compared to UEL. Performance wise, the Xforce EL headers provide 8 to 12hp and 15 to 20Nm more atw.
EL headers distribute the exhaust gas temps evenly unlike UELs where the longer runners linking cyl 2 and 4 are hotter leading to more wear in these 2 cyls.
Do pop by the workshop during the coming week if you want to take a look. We will be installing these on a GC8 and GD WRX.
Cheers
