Hi Flow Filters, Belanger Headers, HiFlow Cats, and Corsa should gain you approx 40-45 gross HP on an '06 that has been broken-in properly. Belanger claims +50, but the real world sees 40-45. Add a D-C re-flashed PCM and you get 50.

ps,,,,,all the above are on a year-end sale!

I saw about 35rwhp with my corsa and header combo, and off road pipes. As jon said, with DC tune and those mods I gained 50+ rwhp.

People have seen anywhere from 10-25 rwhp on different dynos when just adding headers. My buddy was on high side, he had corsa and no cats, when he added headers few weeks later he got exactly 25 rwhp on same dyno.

Not to hijack this thread but what type of HP gain can I expect on a 01 Gen II with just S&B filters, high flow cats and Corsa 3" exhaust?

power gains aside, I gained the sound I wanted.

Id bet $5 that you have 1 very low tire, but I would aslo check the brake fluid reservoir

hi jon brake fluid res is ok.i didnt ck the tire presser but i would think my low tire pressure light would come on,im thinkin its a wheel speed sensor.

I dyno'd 3 of these and saw on average about 25rwhp and 30 w gain. Also, with the headers, there was a slight loss of power below ~4000 rpm and a slight increase above ~4000. That is normal with a header install... but just don't be surprised. peak was up about 10hp w/ the headers only.

not as much of a gain as it is on the older cars... but still noticeable. If it were me personally doing the mods, i would not do headers on a gen3... i'd just to the exhaust.
