rs5

There is a cherry bomb and a fuel programmer on my 08 and I was wandering if I took off the cherry bomb do I have to change the amount of fuel on the programmer? And also how much power will I lose? If anything because of the programmer? and I do have the rs5 yoshimura exhaust and air box lid...

I'm in need of a Yoshimura rs5 full exhaust.. Let me know if you are selling!

Looking to buy a header pipe for a yosh rs-5 slip on. Thanks!
