I do not care about how LOUD my car is. Remember my first real mod was a set of Stoptechs. I talked to one speed shop, and they where saying catless DP and pro-tune is the only way to go. Is this correct? Does a pro-tune get you that much more over the Cobb stage2. I would like this car set-up for Road-curse track events. I could care less about 1/4 mile keep that in mind.

a protune is 100% worth it.

catted or catless is your choice. if you dont care about loudness or flames, and have a little extra money, get a catted dp.

Catless is going to give you less restriction, which is good. A Pro-tune is always better than an OTS tune because it is tailored to your car. Cobb's maps are great starting points and tune the car for more power while keeping a healthy margin for safety. A Pro-tune will get you the most power you can get without blowing your car up. The WHP difference between an OTS tune and a Pro-tune can be pretty substantial. Also, if you have the right tuning software, your tuner can tailor your tune for more roadcourse racing power than 1/4 mile power by altering how much boost and where it will kick in in the powerband. Catless and Pro-tune all the way.

Yes, a Protune will give you a lot more power over the stage 2 map from Cobb. Your vehicle is getting tweaked specifically. Not just a shelf map for all Turboback STi's. Catless, or Catted. Its up to you. Will you be running in Leaded gas?

Sorry Sorry sorry what was I thinking ( I was not) Unleaded please...Hangs head in shame.

At the power level of Stg2, a cat will not decrease performance.
A Stg2 OTS Map, and a Catted DP will do wonders for your car.
Get a couple parts on your car and then get it pro-tuned. As a Pro-Tune on a Stg2 will only yield minimal HP increase over the OTS map.

i could give three ****s about what cops think of my car as long as we drive like a normal people on public streets i think we should all be fine.

PS Catless and Protune FTW!

Sometimes you have to worry about noise, even at racetracks because some have sound level restrictions.

Personally, I would not take a stage 2 OTS map onto a road course, especially after seeing how poorly my '05 took to it. Protuning is the only way to go and you can specifically request a road course-safe tune. Tweaking for the 1/4 mile is different because the car is only running hard for about 12-13 seconds. On the road course you are running 20 minute sessions at full tilt.

At stage 2 levels, my tuner said a catless exhaust might only buy you another 5whp (I only had one hi-flow cat.) To me that isn't worth it, especially when it comes time for emissions testing (that might not affect you.)

Mine may be a unique situation (Cali 91 Oct.) BUT when I plopped in my Cobb catted DP into my '08 with Stage 2 OTS map for Cali, my tuner said it is so dialed in that he would be able to extract MAYBE another 5 horses. The tuner, btw, was Dan Harman, so not some newcomer learning his way around.

Again, my situation may be unique because I understand that there are vehicle to vehicle differences and the big difference being the fuel you and I use but just be aware that at least one of the OTS maps made a pro-tune redundant.

Getting a pro tune is like the same kick in the butt that stage 2 did. catless stinks too much, but isnt too loud.

Did you get a Pro-tune on your '08? It would be interesting to compare/contrast your experience with mine since it seems to be one of the OP's concerns.

is this true, getting a catted dp will be louder and flames.
