The i30 N's turbocharged 2.0-litre engine has made it one of the most popular hot hatches in Australia to upgrade, and a cat-back exhaust is the go-to modification for a bigger, more aggressive note and marginally improved turbo response. Because the N runs a larger factory pipe diameter than the standard i30, parts aren't interchangeable — head to our standard i30 range if you're working on the non-N model instead.

What's the difference between the i30 N and standard i30 exhaust?

The i30 N uses a larger diameter system suited to its turbocharged 2.0-litre engine, so parts from the standard i30 aren't interchangeable with the N.

Will a cat-back exhaust fit the i30 N without a tune?

Most bolt-on cat-back systems don't require a retune, but it's worth checking the specific product listing for any tuning notes before ordering.

Does upgrading the i30 N exhaust add power?

A free-flowing cat-back can modestly improve turbo spool and exhaust note, though most owners notice the sound change more than any measurable power gain.

Is the i30 N exhaust legal for road use in Australia?

Yes, as long as the catalytic converter is retained and the finished system meets ADR noise limits for your state.
