I'm interested in anyone who has done this to their Evo 9, specifically a 272 exhaust cam and stock intake cam. Was it worth it? Did you notice decent gains in bottom end torque and initial spool up time? Thanks in advance

 

If you're swapping one, why not do both......

 

I have a set of BC 272 for an Evo 8 sitting around, no one seems to want to buy them off me, so I've been throwing around the idea of putting the exhaust one in my 9. Just wanted to see if it was worth the trouble.

 

It's not worth the trouble. Do both, or do neither.
