Are these results on the c that you have done the 5.5l swap in? If it is, can we expect to see the same gains on the C43 stock motor? Also, I don't see a lot of info on Ecu and chip tuning on these cars....is this something that could further the gain in power as well. Sorry, I'm a newb when it comes to these cars and am in the process of purchasing one.

Yes this is on my C43 5.5l . You will still see definite gains on the 4.3l motor. TRUST ME!!! Just build the exhaust exactly as I stated and you will love the results. More tq, midrange and topend power from new high flow secondary 100cel dual cats to 2.5"y pipe with 3" outlet going back with a 3"SS pipe all the way back to the muffler. Later I would recommend the Kleeman headers which will replace all the piping b4 the 2nd dary cats.

The ECU can be upgraded by Powerchips,Superchips,Renntech or Kleeman!

I like this idea. My CLK55 begs for a slightly more aggressive sound + more power cannot hurt

To itemize:

(2) 100-Cell Cats
(1) 2x2.5" to 3" Magnaflow Y-Pipe
(1) 3" x 12"/18" Vibrant Resonator
(1) Custom made 3" piping from Resonator to stock 2.75" piping just after subframe prior to muffler

I'm gonna take my car to an exhaust shop and ask

Don't for get mandrel bent 3" piping. Makes a difference. And not all exhaust shops do it.
