I’ve got a 2018 YFZ450R completely stock except for untuned vortex. Slow asf. I’ve got a full exhaust system on the way as well as stage 2 intake hot cam. Looking into fci intake. I just want something solid for the trails with some actual torque. My main question is what should I do for an exhaust cam? I’ve heard the 09-13 oem yfz450 exhaust cams are a good way to go. I’ve also read about the yz cams but I already have the Hotcam and I’m gonna use that. So any recommendations on exhaust cam?? And also a good place to get it dynoed in or near Indiana?

You'll noticed a difference when you toss the stock intake and exhaust aside for an FCI/Exhaust (Rossier, RP, DASA, Barker, Empire, etc....) The STG3/09-13 OEM intake camshaft makes a noticeable difference in power delivery. I haven't noticed much seat of pants difference between exhaust cam swap outs.
