I've upgraded my muffler (Top Speed), and was wondering if it's worth the money to upgrade to a high flow catalytic converter on my 07 Exige S? Any advice will be greatly appreciated.

OEM Manufactures are getting very good at building exhaust systems.

Similar to mufflers, there just is not much HP hiding in the cat, and in some rare cases they have been known to cause CEL codes.

If you need a cat, they are worth looking at. If you are just looking for bolt on HP, not so much.

Agreed, not worth the cheese; however if your state does not emissions test (a la fla) straight pipe is worth the cost.
