Heard and read in previous post some members keeping exhaust piping since its a pretty well design and changing just the mufflers(For weight and sound). I know this wont give much performance.

When looking around on ebay, Ive seen different magnaflow mufflers. Some wider and some more circular.

Here are some links of the ones I'm interested in. My questioin was whats the difference with the size of muffler. I would imagine that the larger the muffler, the more quieter it would be compared to the circular design since in most aftermarket cat back exhaust, they use the circular design.

Thanks for any help

Why would you spend the money to do that when you won't get any more power, and it still won't sound that great? For a little more money you could get a decent exaust on ebay like the invidia.
