we've got several good places in Kitsap area 9(if you wanna ride the ferry over)

Kitsap Muffler Kitsap Muffler Home Page being the first one I'd send you to for a basic exhaust

also
Bucky's Bucky’s Complete Auto Repair. Mufflers, Brakes, Radiators.

I've had both shops do work for me
(pricing seems to be Hit or Miss, depending on the day you ask)

but for the price,
you can just pick up a full exhaust kit from LMC truck or JCWhitney and bolt it on yourself
(or talk to a shop about installing one of these for you)
