034Motorsport High-Flow Catalytic Converters are designed to replace the restrictive OE catalytic converter, and allow for quicker spool while increasing horsepower and torque throughout the powerband.

We construct them from stainless steel tubing, and utilize a high-performance 250-cell stainless-steel-matrix cat. They feature CNC machined flanges to prevent warping and expansion, factory-correct exhaust hanger location, and 2 oxygen sensor bungs in the proper locations for the factory sensors. Full 3.5" tubing is used at the turbo outlet, with a smooth transition to 3" after the cat.

The high-flow catalytic converter is a complete drop-in upgrade; will bolt up to any stock/stock-fit turbo and stock/stock-fit exhaust. Professionally assembled in-house, TIG-welded and backpurged.

Features:

  • Stainless Steel Tubing
  • TIG Welded
  • Application-Specific Flanges
  • Factory Oxygen Sensor and Exhaust Hanger Placement
  • Installation Hardware Included!
  • Dyno-Proven Horsepower and Torque Gains!

We've seen gains of over 24WTQ and 27WHP on our dyno on stock turbo tunes.

Fitment:

  • 2009 - Present Audi A4 2.0 TFSI (B8)
  • 2008 - Present Audi A5 2.0 TFSI (B8)
  • 2008 - Present Audi Q5 2.0 TFSI (B8)

*** Direct bolt-in for OEM cat-back exhaust, or aftermarket cat-back exhaust systems designed to fit with the OEM catalytic converter. Will fit Quattro and FWD B8 Audi A4 2.0 TFSI models equipped with Manual, Tiptronic, or CVT transmissions. Does not fit Right-Hand-Drive (RHD) vehicles.***

Please Note: Our Oxygen Sensor Spacer is sold separately, and is recommended to help prevent the MIL or CEL if you do not have Stage 2 software that defeats the MIL or CEL when removing the stock catalytic converter.

Maximum joint comfort and durability
Color: Pink, Style: 1/2 Inch
I absolutely loved the color, and it offers incredible cushioning without sacrificing stability during balance poses. It is dense, doesn't lose its shape, and springs back instantly. The materials are high-quality, and it doesn't have that strong plastic smell that others often have. It is worth every penny for the comfort it provides.

PLUSH! Fabulous yoga mat!
Color: Black, Style: 1/2 Inch
SO comfortable! It feels like a soft memory foam padding. I use it for several exercise classes and it is great for all of my needs! I love the strap it comes with to keep it rolled up in between classes and the ability to carry it anywhere.

very comfortable and thicker than a regular yoga mat
Color: Pink, Style: 1/2 Inch
This yoga mat is very comfortable and thicker than a regular yoga mat. The quality is excellent, and it doesn't have that strong rubber smell that many mats have. I'm very happy with it!
