3. Install circlips and flanges from the stock system onto both the new head pipes.

4. Apply a small amount of anti-seize compound to the threads of the O2 sensors and install them into the new head pipe. Install supplied 18mm to 12mm oxygen sensor adapter then install 12mm oxygen sensors.

5. Install the front header assembly (D1134FB/D1334FP) into the front exhaust port first.
   Use the stock flange nuts, do not tighten at this time (Figure 2).

6. Install the rear header assembly (D1135FB/D1335FP) into the exhaust port. Use the stock flange nuts, do not tighten at this time (Figure 2).

7. Slide the dog bone nute plate (A195HW) into the muffler bracket and slip muffler can onto front and rear head pipes. Hand tighten muffler to the mounting bracket using supplied 5/16-18 flange head bolts (A240HW, x2) (Figure 3).

8. Tighten the exhaust system nut, bolts, and clamps in the following sequence: (1) Head flange nuts (x4), (2) Muffler body 5/16-18 flange head bolts (A240HW, x2). Make sure the head pipes and mufflers are aligned parallel,.(Figure 4).

9. Install springs using supplied spring puller; there should be about 2” between spring tabs (Figure 5).

10. Route the front O2 sensor wire along OE path and plug into the Grey connector.
    Route the rear O2 sensor along top of the transmission along the OE path and plug into the Black connector.

11. Install 3/8” lock washers (A286HW) on both 3/8”-16 (2.25” & 3.5” long) socket cap screws (supplied). Using these bolts reinstall the floor board with two machined spacers (supplied) on the forward mount (A902HW) and back mount (A667HW).
    (Figure 6)
    Note: Machined spacers are located between the floor board supports and floor board mounting plate.

12. Re-install the right side passenger floor board, right side panel, then saddlebags.

13. Be sure to tighten all hardware before starting your motorcycle.

14. After installation and before starting the motorcycle, completely clean pipes and muffler with cleaning solvent and a clean soft cloth that will not leave residue.
    NOTE: Any residue, oil, or fingerprints will stain the finish when the metal heats up.

EXHAUST CARE (STAINLESS)

1. When installing a new set of stainless pipes, make sure your hands are clean and free of oil. After installation, thoroughly clean pipes with a soft cloth and cleaning solvent that will leave no residue (glass cleaner, alcohol, acetone, etc…) before starting the motorcycle.
2. It is considered normal for stainless steel exhaust systems to discolor due to heat.
3. High performance engine tuning utilizing a dyno will likely result in severe discoloration.
4. Avoid long periods of idiling as this can cause discoloration. Intake leaks can cause the engine to run lean and overheat and this could lead to discoloration.
5. Make sure there are no exhaust leaks at the junction of the exhaust pipes and cylinder head. We recommend replacing gaskets if they are worn.

EXHAUST CARE (BLACK)

1. When installing a new set of black pipes, make sure your hands are clean and free of oil. After installation, throroughly clean pipes with warm soapy water and a soft cloth.
   Dry with a clean towel to remove any residue before starting the motorcycle. Do NOT use anything abrasive to clean pipes.

2. Avoid long periods of idling as this can cause discoloration.

3. Intake leaks can cause the engine to run lean and overheat, this could lead to discoloration.

4. Make sure there are no exhaust leaks at the junction of the exhaust pipes and cylinder head. We recommend replacing gaskets if they are worn.
