DOES THE NEW ZX10r HAVE A CATALITIC CONVERTER?

 

Yes it does, look at the lower bolt up point after the headers under the ride.

 

if i put a slip on exhuast, would it have no effect on exhaustflow because of the cat being the restriction?? Or would i still gain a few hp?

 

Everything restricts a little, my guess is you would still get a little boost.

 

You may gain a couple hp/tq with a slip on. You would also gain what others want is noise only. Kinda depends on what you want. For example, I chose to use and learn how to program the kit ecu for stock headers and pipe. I have no answer just yet on how or why I chose that method. (just my beliefs) Just my thinking. Good luck in your thinking as well.
