Yes and no on the computer thing. Worth a try. It is possible to install a muffler backwards, not sure of the effects of this but may be worth finding out. What brand/ size in and out is your muffler. and did you put if on or a shop?

why did you have to replace the muffler? Do you have a check engine light on?

The only reason a muffler would have to be replaced would be because it rusted out, it wont cause a check engine light but you can fail a safety inspection for it.

It is common for converters to come apart internally. I have done quite a few on these vehicles. Sometimes when they come apart they plug the muffler causing backpressure issues. Thats the only reason i ask. extra flow with new muffler could case internals of convertor to move more and cause intermittent driveabilty problems.
