I have a 1985 seville 4.1 v8. I was driving down the freeway when I heard a lound noise like a tire had blown. Then my car started to sound like it had a deep sounding exhaust system (like it had balls). When I got home i noticed a hold in the muffler. What caused this? The car runs fine. Will it pass smog for CA Change of owner ship? How much should I be looking at for a repair?

Two things:
1. The muffler was rusty and old in the first place.
2. You had a buildup of unburned fuel in the exhaust which finally ignited, causing your "boom".
You will have to replace the muffler to pass smog, and likely you will have to fix whatever is causing the buildup of unburnt fuel, too.

It was probably just an old muffler. You may have hit something. A new muffler should be no more than $100 plus installation. It should total 125 or less for muffler and all. BTW you will probably not pass CA emissions with the hole in the muffler.

Carb is running too rich or you have a super dirty air cleaner. Bad O2 sensor will also cause a build up of volatiles in the exhaust system.

it was just due to go out...mufflers don't last forever and normally they give no sign of going out.
depending on the garage you take it to...and do take it to a garage to have it fixed...it's a mess if you try it yourself. depending on what you have to have replaced I'm gonna guess upwards of $150 if it's just the muffler...if other replacements are needed then figure that in.
Hope this helps
