Well im looking into fixing my exhaust a bit... i was thinkin of getting a high flow cat and then making the piping bigger till it gets to the stock muffler... would that be a good idea and would you think it would sound good, better, worse? well any input would help me in either investing in puttin my dual mufflers on or trying the piping enlargement.Thanks

I do not think you will notice a difference in sound(s) by going larger... However any time you increase the size the flow can move that much fast out the muffler, which is a plus!
