Racing Dynamics Sport Headers (w/cats) - Thoughts?

![Default](https://rennlist.com/forums/images/icons/icon1.gif)
Looking at adding headers and an ECU tune to my 991.1 base. I wanted to add catted headers in hopes of eliminating Check Engine Lights (CEL) error codes and possibly passing CA smog check without having to remove the headers every time. I have read that 200 cel cats might potential pass CA Smog tests. I assume I will have to flash back to a stock ECU tune when I smog and I will need a smog guy that will "look the otherway" in regards to a visual inspection. With that said I really like the Soul Catted headers but they are really expensive. I found a pair of Racing Dynamics Sport Headers (w/cats) that are less than 1/2 the price. Both run 200 cel cats. Back in the day when I ran BMW's, Racing Dynamics were a quality option but I know nothing about them for Porsches.
Does anyone have any real world experience with the Racing Dynamics Sport Headers for Porsches? I get that the Soul Headers are more refined but are they worth the 2.5x price premium? From a performance perspective are they similar? What am I missing?

The IPE makes an F1 exhaust that sounds great but cant find a clip of header sound. Anyone install any of these ?

Look for HJS catalysts as they can "take a licking and keep on ticking". Respected brands like Cargraphic, Fabspeed, etc use only HJS cats.
