Kinetix vs Helix HFC's?
 
I tried to do a search to compare these two. Which one and why with the Greddy Evo2 exhaust? Want to get your opinions. Thanks

i havent heard anything great about helix hfc's. im using kinetix cats right now and they sound great with my borla td. very minimal gains from either one. the cats made the car sound a bit louder and more aggressive.

14,000 miles and the Kinetix High Flow Catalytic Converters are in good shape. Very pleased with the durability.

Don't even think Helix makes their cats anymore. Myself and several others had cracking problems and other issues with them, so might as well go Kinetix.

They must be making them a little better than they used to. I had my kinetix cats for about 4 months before one of them totally cracked in half. The weld quality, even on the new ones, looked horrid.
