QUOTE(K3V1N @ 9 Nov 2009, 09:32 AM) <{POST_SNAPBACK}>Hi guys and girls,was just wondering what sort of powergain a downpipe will give you,is it worth buying aswell,I'm running a decat and cat back system with codered software at the moment and not sure weather to buy the downpipe or not...
On a downpipe alone the power gains will be negligable! However combined with a de-cat/sports cat you will see a few horsepower more! The real gains though are in flowing the hot gases out of the turbo much more efficiently thereby reducing heatsoak in the turbo body! This keeps inlet temps down and makes the car produce its power more reliably specially in the warmer months! It also allows the turbo to spool up a bit quicker!Definitely a worthwhile addition to any ST!
