Installed SPT Catback Exhaust

I Just installed this yesterday on my 04 sti and it's everything I was hoping for. System is 3" from the cat back. Looks and sounds awesome, very deep and throaty but not too loud, which is not bad for a bosal can. The tip has SPT etched on it.
Performance wise, it's hard to tell, since I'm not done with the break-in period yet.
The one thing I was wondering was if I should reset my ECU? Any advice would be great.

I reset mine and it mad a difference

I installed a helix downpipe and drove around for a while and enjoyed the turbo whistle. A fews later i reset the ecu and the car seemed to pull alot harder. (Maybe it was colder or something)

I wouldn't reset yours just yet because your still breaking the car in let it learn on it's own its.

It takes roughly about a week of moderate driving for the ECU to update its settings when you change anything. If you're still breaking it in, it probably would make no difference to reset the ECU. By the time you're done breaking it in, the ECU would have adjusted to it.
Most people do ECU resets because they have no patience...

Post up your thoughts on the system once you do break it in. I am interested in the catback especially since they're like $297. from W&L subaru till the 31st.

How is the sound at idle and WOT? Post some soundclips if you can!
