GAS High Flow Cats, Audi 3.0T Supercharged

If you're looking for our catless test pipes, they can now be found here.

-------

As many people know, tuning your supercharged 3.0T beyond just a single pulley setup can drastically shorten the life of your stock catalysts, and even cause engine damage if left alone.

After installing many poor-quality, low-cost imported test pipes, we began development on a high-quality test pipe that would last. Our test pipes (like all of our products) are manufactured from start to finish in-house in Ontario, Canada by our certified TIG welders and go through thousands of hours of torture testing on our 3.0T development vehicles. Don’t be fooled by companies offering thick, heavy alternatives.

These high flow cats feature the same perfect fitment as our catless versions, but are 100% EPA compliant and do not require O2 spacers.  

This is the solution you've been waiting for! Stop sacrificing HP for emission issues and check engine lights.

Features:

• Thick-wall 1.6mm T304 stainless tubing
• 10mm T304 stainless laser-cut flanges, welded inside and reinforced outside to prevent common flange warping/cracking
• 1/8” T304 stainless mounting brackets 
• Fully hand-TIG welded and back-purged for strength and longevity
• True 2.5” with 2.5” flanges, no tapering down to OEM size, eliminating the bottleneck when running aftermarket downpipes/cat-back
• High quality 400-cell GESI dual S-wound sport cats rated at 500bhp each
• Proven on hundreds of Stage 2+/Stage 3 dual pulley setups over 540whp/660bhp
