Default How To: 2008 STi HKS axle back.

This is the rear muffler section by HKS. HKS 2008 STi Legamax Premium Rear Section. This is a JASMA legal system, that meets all the requirements for street driving in Japan.
Features 4 Ti colored 90MM tips.
With a 65MM Pipe Size, that matches up perfectly to the OEM mid section.

Things included : Muffler, 2 bolts, 2 nuts, 4 washers, Gasket.


This is a very easy install and takes about 10-15min.



Tools:
2 14MM wrenches.
2 ramps to drive the car on to

1) Back up the car on to the ramps so that the rear of the car is up in the air.
Then locate the 2 bolts that attach the rear section to the mid section.
Get your 14mm wrenches and take off the OEM hardware.



2) The car has 4 hangers that holds the muffler on to the back of the car.
Take off the axle back from the hangers.


3) After the hangers are off the System will come off.


Just a quick comparison of stock vs. HKS

HKS Weight.


Stock Weight


4) This is what the underside will look like after you take off the muffler. You can see 3 of the 4 hangers (4th one is in the shadows)



5) Now put on the HKS rear section. 1st put on the hangers, then the hardware with the gasket.

6) Stand back and enjoy your new system




Sound wise, this is a quiet system. With the windows up the system can not be heard, and is very easy to live with. If you step on the throttle you will hear a nice rumble, but nothing that will wake up the neighbors.
The fit and finish on this HKS system is as good as it gets. Everything lined up perfectly with not issues.

The car has a APS manifold, Invidia DP, Stock mid pipe!

The reason for the price is 2 reasons.
1) The GR chassis use a completely different exhaust layout, and if you notice in the images. Its a much more involved manufacturing process compared to the previous GD chassis. More material, and more involved manufacturing results in a higher price.
2) This system is Jasma Legal in Japan (Japanese version of DOT). To have products be legalized by any government or racing group, increases cost. This is similar to SFI or FIA rating on racing seats and other components. For example, this is for example why Sparco and Recaro seats are so expensive. Last I heard about 2 years ago, to get a SFI rating on a seat, cost 25,000 per seat. And DOT/ Jasma ratings can be just as high, if not higher.
