Today we are installing an old-school HKS Hi-Power onto a 1992 Nissan 240SX SE.This is an older HKS unit with the old school dual exhaust tips, meant for NA applications.
Tools you will need for this install :
- HKS Exhaust part number 31006-KN005
- Breaker bar
- 14mm wrench or socket
- Spray on lube
First raise the car up and locate your cat, depending on your vehicle and how old it is / exposure to rain / elements it may be rusted. If so use a can of Blast Away or similar product to get the nuts lubed up.
Next undo the 14mm nuts holding the cat to the exhaust midsection.
Now locate your exhaust hangers forward of the gas tank and to the left of the tank, held on by 2 14mm bolts.
Now you can drop your entire exhaust as one piece, make sure to take care when removing the catalytic converter bolts, as they tend to rust and may strip if not removed carefully.
Here is a comparison shot between the stock unit and the upgraded HKS catback.

Now hang the rear muffler section onto the back of the S13, re-using the factory rubber hangers.
Next bolt up the midpipe to the cat, securing it by reusing the 14mm nuts you removed. Now line up the midpipe with the rear section, making sure to make a positive seal with the supplied HKS exhaust gasket.
Now tighten her up and you are done!
Enjoy and good luck!
