trying to figure out the exhaust for my 07

I just found a really good deal on an FMF Q4 silencer, it doesnt have the header pipe.
what can I expect from it, does it need the FMF header to work?

I believe that completely stock you are at 82 DBs and when you remove the pea shooter (like I have) you are at 88 DBS. Most aftermarket pipes are just below 93/94 DBs.
