Without the heat shield it costs less, but yes you have to pay for OEM quality:

About the feel, it won't change much in mid range torque. After the 5k RPM the sensation is that you have a VTEC. This is with a combination of the header and the Cosworth stage 1.0 kit. The tune is also strong on high RPM, but I cannot attribute all the gains to the tune. This is a comparison graph of a pre-17 car (blue & yellow) and a post-17 car (red & green). You can see the difference especially after 5.5k with a bump in torque:
In the stock +'17 cars there are a few more changes, but you get most of the feel with the new header, a better air filter and a good tune.
Finally, the sound is more racy on high RPM.
