Jiarear Carbon Fiber Dual Exhaust Tips — F22/F30/F32 2.0T (N20/B48)

The construction is worth paying attention to. The outer shell is genuine high-gloss carbon fiber — lightweight and visually sharp — while the inner layer is stainless steel finished in a heat-resistant black coating. That combination isn't just aesthetic: stainless steel handles exhaust heat and corrosion where carbon fiber alone wouldn't hold up long-term. Integrated sound-absorbing holes built into the internal structure help knock down drone and resonance, giving the exhaust note a slightly more composed character without any additional hardware.

Fitment spans a broad range of non-M four-cylinder models: the 228i and 230i (F22/F23, 2014–2019), 320i, 328i, and 330i (F30/F31, 2012–2018), and 428i and 430i (F32/F33/F36, 2014–2020). These tips are not compatible with M Performance trims or any six-cylinder variants — the 335i, 340i, 435i, and 440i all run larger OEM pipe diameters. Confirm your stock outlet size is 2.5 inches before ordering. Installation uses stainless steel clamps and is generally bolt-on, though some vehicles may need minor trimming of the stock exhaust pipe for a flush, clean finish.

The set ships with both left and right tips at 9.4 inches in length and 7.6 inches total width — dimensions that fill out the rear diffuser properly and match the quad-exit aesthetic without looking undersized. Jiarear backs the coating and build quality with a one-year guarantee, offering a free replacement or full refund for any finish or quality issues that arise within that period.
