You should order the tips online. They are about $35 a piece. The rest, if done at the right exhaust shop, with the muffler included should be less than $200. Overall I think I spent about $280.
Also the sound is far far from overbearingly loud. When I first got the exhaust done I could barely tell I changed anything. In the next week or two it did get a little louder as the muffler got broken in. The tune did enhance the sound of it.
