^Agreed.

You may lose 3-5bhp, but you wont notice it.

Exhaust note might change a bit too

When I got my powerflow done, I asked about de-cats. He said not to bother, as small engines need back pressure, and a cat provides the correct amount of back pressure for the system. Said by removing it would probably lose.

He said you want back pressure before the cat, but then as free flowing after the cat as possible!
