Premium rear section with ceramic-coated tailpipes for BMW F30 335i and F32 F33 435i
Give your N55-powered 3 Series or 4 Series the soundtrack and refinement it deserves. This high quality rear muffler upgrade is engineered for the BMW F-chassis turbo straight-six, reducing restriction for sharper throttle response and delivering a deeper, richer tone that stays civil on the motorway yet turns purposeful when you lean on the throttle. It is the ideal OEM+ sound upgrade for daily use, weekend blasts and everything in between.
A tuned Helmholtz resonator targets low rpm boom to keep in-cabin resonance in check, so you get tone without the tiring drone. Constructed from 100 percent 16 gauge T304 stainless steel for superb durability and corrosion resistance, it mounts to factory locations for a true bolt-on install and finishes with dual 89 mm black ceramic-coated tailpipes for a subtle, stealthy look.
- Sport rear section for BMW F30 335i, F32 435i, F33 435i Convertible including AWD xDrive
- Reduced back pressure for crisper response and a stronger, more characterful exhaust note
- Helmholtz resonator design helps cut low rpm resonance and cabin boom
- 100 percent 16 gauge 304-grade stainless steel for long term durability

Why choose this upgrade
We have fitted this system to customer cars and to our own demonstrators. Feedback is consistently positive. Owners love the refined cruise, the sporty growl under load and the quality of the T304 stainless construction and ceramic tips. If you want an OEM+ look with an engaging soundtrack and minimal drone, this is the rear section we recommend for the F30 and F32 or F33 N55 platform.
