Well to quiet it down, add a resanator or even a silencer in the tail pipe. My silencer quiets my car down alot.

The clicking noise you describe is probably an exhaust leak somewhere.

ok ill have the shop check it out where i got it put on, is it my header gasket???????

If you hear it from the front of the car, it's probably the header/downpipe connection, or the header flange where it bolts to the head. You can check it out yourself if you're careful. Wait until the exhaust has cooled off, then start the car and put your hand around the header/downpipe connection, and the header to head connection (this may be more tricky). If you can feel air coming out, then you've found your leak. Careful, the exhaust heats up pretty quick.
