I had my True Duels put in last week. ( Love them ) But now I have a pluged cat, and my system is all welded. Should I just replace that one with another stock one? Or should I do High flow? and will It be louder. I don't really need louder.

 

The high flows will be louder for sure...If you don't want the extra sound, go with a stock replacement

 

Agreed.

 

Just get the hi-flows. When you have to pay to replace cats, the last ones you want are OEM cats.

 

hi-flows = $84 each, stock cats = $360 each for the same quiet, and flow restrictive part so...........
