and man does it sound good... nowhere as loud as my WRX was, but then again the STi has 2 cats in it while the WRX had only 1 hi flow cat and a bigger turbo... even though it isnt as loud as the WRX was, the sound is MUCH deeper... this was my favorite sounding cat back on the WRX and i like it even more on the STi if anyone wants to hear it, i'll be at the varsity tomorrow
i had the blitz nur spec r on my WRX as well... but it had a helix downpipe, cold air and a bigger turbo...right now the sti has stock exhaust except for the cat back
