Getting ready to fire up my car for the first time and since it has no windshield and is not really driveable I can't take it to put exhaust on it beforehand.

The engine is fresh but is using a solid lifter setup that was previously "broken in" so I don't really need to do a break-in so to speak.

I am really excited to fire it up but am worried that with 11.5:1 it may be a bit loud and I may not hear rods etc. There is a muffler shop less than a mile from me but I have no way to get the car there first.

what say you?
