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?

yes Mandrel bends are a must.

If GT stock piping is smaller then 2.25 or 2.5 then could i jsut get an adapter or would i be best repiping all the way? If yes then how far back?

Can anyone attest to the way the way a magna flow sounds on their celica.

And before you ask lol i have searched the forum but found that the threads related to this topic werent really helpfull in the how to part.

thanks for the info
