Like this......



I called Magnaflow and talked with them for a little while... He said that it would not be a problem and that the mufflers are capable of handling something like 1800*F??
I cant remember exactly what he said.. but it was pretty high...

I havent had a problem with mine..

 

I use magna bullets. They are the 3" in/out, 4" diameter. There are probably better options for sound reduction however (like the 5-6" ones). Just don't use a chambered or glasspack. You also want the best flow you can get.

 

I have a Flo-Pro FP727 on mine in front of the turbo. It is a dual 2.5" in single 2.5" out and is a chambered muffler. I gained a 10th on the G-Tech after I installed the muffler.
