I have a S4 with a Racing Beat 3" turbo back exhaust, and I am going to need a cat to pass inspection/emissions. I was wondering of anyone has used MagnaFlow Performance Catalytic Converters clicky I am looking at aquiring the 3" w/ air pipe, part Number 94319.

Has any used or heard anything about these cats?

 

If not then what is everyone else running?

 

i did use that exact one, it did pass inspection too!! its loud though so watch it!! being its hollow the sound echos inside it!! but wroked very well!!

 

I used a $30 Catco 3" high-flow cat off E-bay....
It passed me with good numbers, you have to break in the cat for about 100 miles though.

I will probably have to replace it each time I go in for testing, but ****...it's $30

 

true i am so glad i live in minnesota no ermmisions laws!!

 

Right now I have the 3'' racing beat midpipe, so I doubt it would be louder than that...

How long have you had it? Also what kind of downpipe do you have?

 

I used the 3" Catco off ebay and welded some flanges from mazdatrix, I also needed about 5" of 3" from the local Muffler shop to get the cat extended to fit...

Cost about $70 for parts and 1/2 hour of welding...

It also got rid of the C-130 Hum in the cockpit when crusing at 80MPH, I am keeping it on until it causes problems...

The neighbors also like it better! :-)
