Product Description

If you're looking to unlock some serious potential in your late E-series BMW with the N55 "twin-power" single turbo engine, this CTS Turbo downpipe is the real deal. Crafted from T304 stainless steel, these pipes mean business when it comes to maximizing your engine's output.

NOTE: Compatible with late E-series models sporting the N55 engine.

With a 3" diameter pipe coming off the turbo and splitting into dual 2.5" pipes, this downpipe ensures superior flow compared to the restrictive OEM setup. The T304 stainless steel construction, TIG welding, and precision fitment all add up to a noticeable improvement in throttle response, power delivery, and engine soundtrack.

Product Details:

  • T304 Seamless Stainless Steel tubing for durability and performance
  • 3" diameter pipe off the turbo, splitting to dual 2.5" pipes for optimized flow
  • T304 Stainless Steel flanges for secure connections
  • 100% TIG Welded for precision and strength
  • T304 Stainless Steel 02 bungs for sensor compatibility
  • Delivers a great sound and ensures perfect fitment

Designed for E-series N55 engines found in:

  • 2011 – 2013 E82 BMW 135i
  • 2010 – 2013 E90/E91/E92/E93 BMW 335i & 335xi N55
  • 2012 – 2015 E84 BMW X1 35i

Unlock the full potential of your BMW with this downpipe, but remember:

Stage 2 software is required to prevent triggering the check engine light.

Shipping & Delivery

How Shipping Car Parts Works

Shipping times vary depending on item availability. While we work closely with our vendors and manufacturers, inventory accuracy may sometimes cause potential delays.

Unless a specific lead time is listed on this product page, expect to receive an email or communication with an ETA within 1-3 business days of placing an order. Many suspension kits ship within 5 business days while some take 7-14 business days (Excluding made to order products like Fortune Auto). While we strive to keep these estimates accurate, please note that we cannot guarantee the exact delivery date. These estimates are subject to change due to weather, holidays, etc.

Availability on back-ordered or custom made products will very and we will keep you informed via email with any arrival date changes. You will receive tracking information as soon as it is available so you can easily track all of your aftermarket car parts from us here at MartiniWorks.
Due to the nature of products arriving overseas or around the world, orders with multiple products may arrive to your door at different times. All shipping prices are based on delivery to the lower 48 states unless specified otherwise and do not include any duties or custom fees you may be subject to.
Aftermarket car parts like intakes, lug nuts, bolts, and smaller items will typically be shipped via USPS or Fedex; in a standard size box. Aftermarket wheels will be shipped in their original box with tracking via Fedex/UPS via LTL; and may arrive at different times to your door.
Wheel & tire packages will be shipped to you via freight and will require signature and courier confirmation. Please keep in mind that many wheel & tire packages will be off-loaded to you via lift gate and MartiniWorks is typically not responsible for any additional charges for that service.

Inspection Upon Delivery

Upon receiving your items, please promptly check them and inform us of any issues, damages, or discrepancies. Before beginning any installation or taking your vehicle to a mechanic, ensure that all components and boxes are accounted for and match the packing list or provided instructions. We cannot cover any expenses incurred from installation delays caused by absent components. Should you find any parts missing or damaged due to shipping, contact us without delay for assistance in obtaining a replacement. Please note, we are unable to address claims for missing or damaged parts if reported more than 14 days after delivery.
