Default catless downpipe

I have herd that if running a cat-less down pipe with the stage 2 maps on the accessport you will see boost creeps and spikes...? can anyone confirm this?

i have a 2004 wrx and am planning on going stage 2 soon im currently running stage 1 with a catback and its running great. i was wondering if i could go stage two with just adding the stromung shorty dp. i know it wont make the numbers they have posted on the site but it would keep the stock look for those nosy smog guys and its a lot cheaper that a full dp.

Hey guys I own a 2009 WRX and it's all stock besides the Cobb v3 Ap with the 93 octane + AEM CAI. I was wanting to get the grim speed 3 port EBCS and a custom e-tune for the EBCS. If it was your car and you had these parts installed what would be your next purchase? Short throw shifter? A new invidia or Cobb down pipe? I had a turboxs hybrid 50/50 BOV ordered but I canceled it after doing more research and learning it wasn't necessary with only 17-18 psi, and wouldn't make any real difference. My stock BOV already blows off and sounds great doing it. Thanks for everyone opinion, Austin.

I would go with a down pipe next. Biggest bang for your buck as the Subaru down pipe is very restrictive.

I'm installing a cobb SF Intake with airbox and an Invidia Catless DP still retaining the stock catback on my 06 STI. I'm planning on flashing the car over to stage 2+. If I'm not mistaken Those are the right parts for that map but my question is should I be installing the HWG map to prevent boost creep since I'll be catless or should the OTS 2+ map be ok? Thanks!
Edit: I just read a the top of the page and it appears I'm right! Sorry for being lazy. Still any one who has experience with this please feel free to chime in with some advice.

Default 2014 WRX Cobb Stage 1

I have a 2014 WRX sedan and have Cobb SF Intake and V3 Accessport ready to install. I am currently only 500 miles into break-in is it safe/ok to install these parts or should I wait until after the dealer recommended 1000 mile break-in? The dealership never told me it this was safe or not at the time I purchased the car and parts. Thanks for the assistance.

Now that the v3 is out, I feel that this thread needs to be updated. I'd like to avoid asking the "will XXX worth with an AP stage 1 map" but this thread was started 8 years ago...

Good luck. You NEED a pro tune for sure if you want your engine to last and not knock all the time. Call Cobb maybe they might have something for you...

You are going to have to get an E-Tune or something because the OTS maps are for the stock turbo, injectors and intake (or Cobb SF). That is a pretty extensive Mod list

Here is a link in the Cobb Support section that I found very useful about factory tuning and some info on what happens when you use modified parts and their effect on the the boost pressure. It might explain why tuners don't get an incredible gain in horsepower all the time when they put on modified parts on their WRX/Sti.

Adding the V3 will not take away the I/S/S# modes. I word of caution though.....Do not run the intake until you have a tuning solution in place. You need a pro-tune to run that intake. If not the car will over boost and run lean on the stock ECU map which could be fatal for your engine.

well i been running the intake for about 3 weeks now and i haven't notice much difference i do get 1 more mpg believe it or not lol car has now 2800miles. i am in hawaii and there isn't much options for pro-tune. i don't have anything done to the car except the intake... i have always ran intakes on all my other cars and never had a problem are subies that fragile that an intake will make that much of an impact without a tune ???

Its not that the car is more fragile. Its that when the stock MAF goes into an aftermarket intake it will on average throw off the fueling by about 30% (leaner). So that leads to more knock and detonation which would most likely cause you to destroy a bearing or a ring land. What I would do is get the Cobb AP and then get either the AEM or Cobb intake because there are OTS maps from Cobb for those intakes. Again its not that the car is fragile, on a NA car probably would not make a difference, these cars build up boost and your gonna lean it out. If you google do I need a tune for a subaru with aftermarket intake you will see.

This is how the ECU see's the air flow as a voltage value, so you can see how much more air is moving through the Cobb intake at the same voltage compared to the stock airbag. So without the ECU knowing how much air flow corresponds to voltage it has no idea how much fuel to add.
