Hey guys i am planning on ordering a FT86 Speed factory Catted Header as well as the perrin 3' catback exhaust, of course as my paychecks permit

.
I was wondering if i should also be looking at front-pipes/down-pipes/over-pipes(what ever you want to call them)
It would obviously be 2 extra parts to the build, but are they really worth it? are their any true restrictions on stock in that area?
And would they make it ridiculously loud? This is my daily driver, i need some solid noise to make me grin well i drive

but don't need any ear bleeding.
I am somewhat of a novice so if someone wouldn't mind to educate me a little on this topic that would be lovely
Thanks in advance!
