Hey i have a My00 wrx and wanted to get a TBE.

Mate says he can make me a custom one with no cat and no muffler. The actual pipe will be 3 inches and the tip will widen to 3.5 (remember no muffler).

Will this still have that WRX rumble or will it be slappy. Will it be heaps loud.

does anyone know of a thread or movie that has this setup.

Would there be any disadvantages, or just heaps of power gain.

Thanks all.
