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.

Handy size, plush toy with squeaker, great price.
Size: 9 inches - Plush Gumby
Cute Gumby stuffed toy. Bought for my soft-mouthed small dog who enjoys carrying his 'lovey' around in his mouth and jumping onto the bed with it. He is not overly fond of loud squeakers and this squeaker is not loud. I truly find it a bit hard to locate the squeaker but that is a plus for us. This small toy is a bit larger than expected but my dog can manage it. Stuffing is firmer, a good quality toy. I definitely would not give it to an aggressive chewers because half of my past dogs have been small high energy dogs able to destroy a tough toy in a day and no one wants a sick dog or ER visit. But playability is excellent for my gentle and mild mannered 14lb dog.

Pretty Good
Color: Red Nylon Yellow Hotdog
The toy is good for a heavy chewer, but is very slippery. You may want to rough it up a bit before giving it to your dog so they can hold onto it.

Very suitable toy for dogs it’s too resistant. The material is good and very safe. The size is perfect for a larger dog. They love to chew on it.
