Is this or the 4 inch version louder?

the 3.5 & 4" refers to the canister size/diameter, not how loud it is.
I have a p/c t-4 slip on will this end cap replace the modular one?

This cap will only work with the modern Pro Circuit mufflers that have a 3.5" diameter.
What does it do?
what does it do and i have a stock pipe on my 02 xr 100 and the end is flat with 3 holes do i just scew it on or do i need a spark arrester

This is just a replacement end cap for the pro circuit t-4/ti-4. If you are running your stock exhaust i cant guarantee it will work.
Will it work?
ok, the answer is going to be "only fits pro circuit exaust" but it says it will fit my bike. could it have the same bolt pattern?

it could but most likely not, unfortunately we do not have the specs as far as bolt pattern. it says it will fit your bike because it will if you are running a pro circuit exhaust
Does this cap fit over the stock cap or does it replace it?

This replaces the end cap on the T-4 and Ti-4 exhaust.
