P0420-CATALYTIC 1/1 EFFICIENCY

Just got this code today, is it what I think it is? The catless downpipe?

 

maybe dude...

 

would a s2 wastegate on my stock srt4 be good,bad, or nothing? I know the wasategate is the best bang for buck and the tension on the stockwsg is 4psi, would the s2 have tighter tension and would it be ok to use on a non stage car?

 

igotboost - nice hijack it would be fine.

izzy - w/out s1 and having a catless dp that code will pop up on a fairly regular basis. get s1 and you'll be ok!
