Could you explain a bit more about the problem you are having?
Oh... you mean that you have an exhaust leak....
Ok.. well without looking at it, I cannot tell you what part of the exhaust system will need to be replaced. However, mufflers are common but it could be other things in the exhaust system as well. Just go to a muffler shop. THey will show you whats leaking and will most likely give you the best price.
THANKS FOR THE ANSWER DO U KNOW IF THATS EXPENSIVE TO FIX
Well if the engine stalled then that could have caused it.
ALso, if something was binding up like a brake caliper or a U joint, that would also cause it.
If it is not stalling all the time, then I would not worry about it.
