Is it worth it..., Magnaflow? Options

[urbandork]

Im slowly thinking about putting a magna flow muffler on my 6th gen. But im wondering is it worth it? Im wondering more about sound then performance but both do matter.

How much diffrence in noise does it make? How much deeper is it?

Also i have a GT if i go for a 2.5 over a 2.25 is there an adapter that i can use to keep the stock piping or would i have to get 2.5 piping all the way from the down pipe and back?

Whats the stock size for GT piping n e one know?

Ive search the forum and found that when it comes to muffler suggestions its the magnaflow or flowmaster. Ive been told that magnaflows are better. Is this true or a simple bias?

personally, a buddy of mine has magnaflow, and I hate the way it sounds, some might like it, but its too loud at a low rpm

but he also has crush bent piping, mandrel bends make a differance

I think (don't quote me on this)
the stock gt pipe is 60mm, like 1.7"

someone correct me if I'm wrong(which I prolly am)
