Power gain question!!

[Makkasteez]

Hello, I am debating on purchasing the Signature Active Autowerke Catback exhaust. Also the Active Autowerke Catless Downpipes. Approximately how much power should I expect to gain w/o dyno tune.
Thanks

You'll get nothing from the axel back in terms of power but you'll shed a bit of weight. The downpipes is where the powers at. Are you running a tune? I've been reading the gains are between 20-30whp with a tune and you definitely feel the difference.

i want a tune once i have a lot more parts, probably not for another couple months,
^thanks

right but a tune will take advantage of all the parts you put it. Stock Tune won't do anything
For example Downpipes, Intercooler will not give you that great of a benefit unless you are running higher boost. Will intercooler will give you better cooling but you might not need it with stock boost.

Sounds like your getting a full catless turbo back. I agree you'll need a tune to take advantage of it, but stock I'd say the free flowing exhaust will produce 15-20 more whp and 30+ with a tune.

Stock tune won't do much. Just the gains from a cat-back, even with an ecu (if you don't have down pipe's) the most gain you will see is 10 - 15 whp if that.
