If you’re looking for an exhaust modification to enhance the sound on your i30N without splashing out on a new exhaust system, a GPF (gasoline particulate filter) 3″ stainless steel delete pipe from RPM Performance is a popular first choice among Hyundai owners.

It’s important to note this article is for those looking to do this at home on a budget – preferably with an interest in doing it yourself. Alternatively, you can use this piece as reference to see whether it’s actually worth doing or whether it may be better opting for a complete new exhaust system. Either way, we’re happy you’re here and we hope this helps you out.

To begin, you will at least need the following to carry out this job successfully:

• Car jack

• Axle stands and;

• A ratchet/spanner set

1. Safely jack up your car.

Safely jack up your car and rest it on at least 2 axle stands. If you have access to hydraulic ramps and a smooth flat surface, even better!

2. Locate the GPF

The GPF on the i30N is the big box located towards the front of the car at the bottom of the downpipe.

3. Remove the GPF

Using your ratchet and spanner, remove the x2 bolts from the one side of the GPF first. Then, remove the x2 sensors with your spanner, followed by removing the x2 other bolts located on the other end to release it from the factory exhaust system.

Here’s what the inside looks like:

4. Install your new GPF delete pipe

Offer up your brand new pipe to the original exhaust system and bolt both ends up fully. Then reinstall your plugs with your spanner and your new exhaust system is now ready to be enjoyed.

Note: This installation process will also require your car to be mapped.
