This is s serious misconception about CATLESS vs CATTED X Pipes.

The position, density and quality of the CAT's will depend on how much gas flow can pass through them and how much back pressure they impose.

This is a dyno graph of the exact same X Pipe with and without 200 CELL Cat's in the position of the secondary CAT's.



As you can see the difference is only that of two different dyno runs which are rarely exactly the same.

Hope that is useful and people request a HFC. If it's not as powerful then the HFC is not good enough.
