Just replace smashed header pipe, or should I just get a new exhaust?

First time on a track last year (some of you may remember the video lmao) I accidentally got some air when I intended to roll everything as it was my first time on a track. Nearing the end of my 2nd lap for that time out (4th lap in total that day) and I gassed it just a touch more than I wanted and got some air. Landed on the face of a jump and someone landed on my bike with their rear tire. Smashed my radiator on the right side as well as the header pipe.

I just saw some deals on Morosports.com and I’m curious. Would you just replace the header pipe and be done or would you do a full exhaust? I don’t plan on racing officially, just for fun at my local track SVR as I’m 29 now and never touched the track until I was 28 lol. So I don’t see myself going pro with this late of a start
