That with a good tune such as BPM etc will put you on the right path without being crazy loud.
If you have neighbors and leave early or people still sleeping you may want to tune out the cold start.

primaries are the ones you want to remove.

Yea just primary, dont get much of anything from deleting 2nd set. They will also act to keep noise/exhaust smell down a bit as well.

i have already removed the primaries

so dont need to do other modification ?

so you have all the basic mods done, what are you looking for? If you are looking for more power you are pretty much maxed out. You will either need to do a stroker motor or go with a supercharger
