Hey all,

I have my TXS TBE (MagnaFlow) from my WRX ready to go on the STi.
I am getting the Stage 2 COBB AP as soon as it comes out for '05.

Here's my question:
I prefer the look/sound of the stock Sti muffler to my TXS one. How much HP/Torque will I be giving up if I use my TBE as a stealthback?

Also, if I order the race pipe, how much will I gain?

Any Idears?

Thanks in advance.
