Another exhaust thread - cat(s) delete?
Car: 2009 C63
Current exhaust mods: Renntech shorty headers (w/ Renntech tune)
Possible next mods: Mike's power pipe, and possible replacement of primary cats with a high flow option
Question: does anyone on here have an exhaust setup similar to what I'm going to do?
Basically, I'm pretty set on doing the power pipe, but I'm not sure if doing a high flow primary cat replacement will be worth the $$$, if it will be extremely loud or drone on the highway, if it will lean out the afr too much, or if it will throw a code. I'd prefer to keep the headers I have, rather than buy a LTH setup.
Input and suggestions are welcomed!
