Did u read the answer that pete gave me what about the the flex pipe its not soldered it has 2 clamps at the end how do I remove the flex pipe
on the flex..
you will need to remove the clamps to remove the pipe,,but,,most times these wont come loose,,and they will be sawed off the,whe n you install it .it will need to be welded on,,if you can get the claps off,,you can buy muffler clamps at your local auto parts store to replace them,,again,,they may need to be cut off then welded back
thanks
