 Steps and Key Points for Installing the iPE Exhaust System
1.Attach the oxygen sensors to the iPE catalytic converter front section (Figures 26 and
27). Note: Ensure the wires are unwound to increase their length.

2.Install the front section of the catalytic converter (Figure 28). Do not fully tighten the
clamp screws; keep the front section adjustable for alignment.

3.Secure the oxygen sensor wires to their mounting bracket (Figure 29). Connect the
plugs and secure them to the bracket.

5. Install the catalytic converter rear section and its mounting bracket (Figures 33 & 34).
Use the dedicated catalytic section clamp (Figure 35).

Note: Insert pipe depth 40~45mm

6. Adjust the clamp to align with the bracket’s bolt position, then lightly tighten
it(Important: Pay attention to the clamp orientation,Figures 36 & 37 ). After alignment,
fully tighten the clamp.

support bars (Figure 38).
Note: Apply appropriate torque when tightening bolts.

7. Install the mid pipe and rear pipe. Lightly tighten the clamps first, then adjust and fully
secure them (Figure 39, red arrows).
8. Secure the rear pipe hanger bolts and tighten them (Figure 39, yellow arrows).
Note: Insert pipe depth 40~45mm

9. Install the tailpipes onto the IPE muffler (Figure 40, red arrows).
10. Install the factory motor, motor baseplate, and springs onto the IPE muffler(Figure 40,
yellow arrows).

11. Reinstall both sides of the IPE muffler and tailpipes. First, install and secure the
hanger bolts and nuts. Then, install the muffler inlet clamps (Figures 41 & 42,
yellow arrows).

13. Starting from the catalytic pipe, tighten all bolts progressively towards the
rear pipe.
14. Adjust the connection between the catalytic pipe and the mid pipe. Secure
the catalytic pipe front flange clamp (Figure 44). Then, tighten the clamps at the
catalytic front-to-rear pipe junction and the mounting bracket (Figure 45).
• Note: Apply appropriate torque when tightening bolts.

Once positioned, tighten the muffler hanger bolts to secure the height.
17. Install the upper muffler body support bar and tighten it (Figures 49 & 50, yellow
arrows). Tighten the muffler inlet clamps (Figures 49 & 50, red arrows).

Note: Apply appropriate torque when tightening bolts.

notify iPE within 7 days and iPE will give a full refund including shipping costs.

3. Product quality problems which are not included in the warranty includes:

Consumables: Under prolonged use, damaged flanges/screws/flange

gaskets/springs/diaphragms/several strips/aluminum adapters… or slight rusting or
discoloration of the product is common and natural.

The heat protector (heat wrap or heat shield) is a consumable and has a limited life span. Due to
difference in personal usage or frequent disassembly, damage caused by wear and tear is
common.

The tips and oxidized blue/purple colors are decorative parts. Before installation, please make sure
that the appearance meets the requirements. Once installed and used, the return or exchange of
the appearance will not be accepted. Please note that the decorative products will be affected by
extreme environments. Therefore, there may be slight discoloration after prolonged use. In order
to extend the lifespan of the tips, DO NOT wash with corrosive chemicals.

A friendly reminder, whether it is a 200 cell catalyst or a catalyst-delete pipe, iPE products are
designed for motorsport and race track use only. By deleting the catalytic converters or modifying
certain parts of the exhaust system, the chances of triggering the CEL ‘Check Engine Light’ and
‘OPF/GPF (Otto Particulate Filter / Gasoline Particle Filter) ’ warning signal are high in certain car
models. Please note, our warranty DOES NOT cover this or any software incompatibilities.
