would a 3g elipse GT stock muffler be better then the 04 oz ones? do u think it's worth the swap over??

 

If you're going to put on a new muffler, you might as well pick the one you like most. I wouldn't expect any sort of noticable power gains from just changing the muffler though. It's the furthest from the head, and the piping size would remain a big limiting factor, as would the catalytic converter and warmup cat.

 

Hmmm I thought about the same thing but for 02-03 OZ.
And the same would stock Ralliart muffler be better for OZ?

 

like hobie said, dont expect any gains from a muffler, you probably wouldnt even get much from a full catback, but if you plan to get a new muffler put on, and you want it to be louder and get a slight bit of gains, then you might want to get a full catback made with no resonator, or get the stock resonator cut. good luck
