Hands down I have to say that the Area-P might be the most popular exhaust for the Ninja 250R. And it makes sense, it has a great mix of price / performance, and sounds pretty damn good.

Following on the coat tails of their original exhaust the Quiet Core tames out the sound and switches out the shortie canister for a longer full canister with the same great looks.
Pricing stays the same starting at $450 (Stainless) to $495 (Carbon fiber).

A dyno chart for the Quiet Core is not available yet, but Area-P states that power delivery is pretty much the same for the quiet core as it is for their standard exhaust. Also, a jet kit is is not needed for this exhaust, but is recommended.

“After testing several other production bikes, we recommend Dynojet kit # 2193 or Factory Pro kit (or similar) to help optimize the fuel curve and further increase power, as the production bikes do have a tendency to run lean in the low/mid range especially.”
