i have the same type of question i have been looking at trying to get true duals or any type of upgraded exhaust. It seems like a muffler would do the same in performance as a catback because it necks down at the y pipe anyways to 2 3/4 or so so i do not see the advantage of getting a 3" catback it it is necked down before to 2 3/4 that to before it enters the i pipe, i would think a muffler would do the same as a catback. Any comments?

I just chopped my muffler off and welded in some pipe in its place and it had a great sound.
If I were gonna put a muffler on I would chop the muffler out of the back and throw a small 1 chamber muffler on the itermediate pipe before the axle and replace the muffler with some pipe to finish out the duals in the rear exit.
Just my $.02

Mine is a daily driver and it doesnt seem annoying to me at all. It sounds great.
Have you run straight pipe?Not quite as loud as you would think.

Save your money and get the cat back.
As per running without a muffler. I cut mine off and ran a week before putting a new one on and it sounded awesome. I will get full exhaust eventually (headers back), just gotta save the money.

i know but if it is 3" cat back it is still necked down to less then 3" at the end of the factory y pipe so i do not see the advantage of getting a 3" catback if it is smaller then 3" before that. Or am i wrong? look at the picture below and see where it is necked down and then expanded to 3"

yes for sure . . the factory y does hurt it definately but my magnaflow isn't necked down that much what brand is that catback?
also if headers and y are in the planned modding future. . might as well get the catback so the 2 can work together in the future. hate to have headers with stock exhaust restricting it

no get the cat back. you have to re weld so much piping for the muffler change. just save time, and get the catack. you will want the additional flow when you want to start makin more power. i was thinkin the same thing, but then realized, the catback is way better.
