powerwrx,

My experience is with a decat’ed standard OEM center pipe on a MY03 WRX which will be _very_ similar to an aftermarket decat.

New age cars seem to have lost the noticeable Scooby ‘burble’ on tick over compared to my old MY00 classic. The decat’ed center pipe brought it back.

‘Normal’ performance doesn’t feel that much different. Although the car does seem to be slightly happier above 5500RPM to the red line. Given that I don’t rag the car through the gears every time I drive it I didn’t feel this gave much more every-day performance. With that said if you want the occasional race off the lights then it will seem a little quicker because you can hold on to each gear for a few more revs.

In summary, Scooby ‘burble’ will be back and very slightly better at high revs.

Decat'ing the downpipe, now that will feel and sound different ;-)

-Steve.
