Ninja 400 Pipe and ecu ??

What brand pipe is getting the best results and best place for ECU flash for the Ninja 400's?

Thanks Jake

 

I went with Spark.

Spark and Akro seem to be the best. As far as ECU Flash, Norton OR TST works really well. I had the TST Flash before I had my bike on the dyno.

 

Spark? not familiar.
Thanks, Ill contact TST

 

Yeah if you look around the ninja400r forums you'll find Spark seems to be the Goto for the 400. Spark Kawasaki Ninja 400 "Konix" Full Exhaust System: MOTO-D Racing (motodracing.com) Spark (norton-motorsports.com)

 

Graves....amazing results.

 

Agree completely. I forgot about Graves. Honestly I dont think you can go wrong with any of the top exhaust brands for the 400. Graves , Akro, Spark , M4. Either one of those will yield great results on the dyno.

 

The pipe and tune together is what make the difference.

 

Graves just came out with velocity stacks and an air box mod for the 400 too. They show a dyno graph on their website of a Ninja 400 with their pipe, ECU and velocity stacks making around 53 hp. I think the airbox mod adds like another 2-3 hp.

I have a spark with a Spears flash. Works the same as my graves with graves flash. Like Ken said, the pipe and tune together that make it. If there is a difference between the two I’ve had, I couldn’t tell, but if I lost 10 pounds I would
