Fitment questions, answered

Will this fit my 2011 E92 335i?
This listing covers the 2008 to 2013 E90/E92/E93. Confirm your exact year, model and engine with your VIN before ordering, since exhaust routing varies by engine.
What is a Z-pipe catback?
It is the cat-back exhaust section in the Z-pipe configuration with valvetronic valves for sound control, built to the supplier's listed specification.
Is professional installation recommended?
Yes. A cat-back install involves the full rear exhaust section. A professional shop with a lift should do the work, and you should check your local noise and emissions rules.

Still unsure? Send your year, model, trim and VIN — fitment verification is free before you order.

Install Overview

Moderate 2–4 hours Jack and jack stands or a lift, socket set, penetrating oil
  1. Let the exhaust fully cool before starting.
  2. Soak all exhaust hardware in penetrating oil well before starting.
  3. Support the factory exhaust, unbolt the hangers, and remove the old section.
  4. Hang the new system loosely first, align the tips, then tighten everything evenly.
  5. Start the car and check for leaks and rattles. Re-check hanger hardware after a heat cycle.
  6. Check your local noise and emissions rules. Modified exhausts are not street-legal everywhere.

Not comfortable doing it yourself? Have a professional shop handle the install. If anything doesn't fit right, stop and contact us before forcing it.
