Default '11 WRX CAI or DP

I'm currently stage 1 93 octane with the Cobb AP & love the noticeable power increase, my g/f also noticed it

I've been studying the Cobb dyno results


Stage 1 93 vs Stage 1 AEM 93



Stage 1 93 vs Stage 2


It doesn't look like there is a huge difference between the 2. Has anyone had any seat time with either of these?? From the research I've done, I've read that the 08+ cats flow much better than the older models, so the hp increase is less with an aftermarket dp??

I don't have the funds right now for both. Would I be right it thinking it would make more sense to put the catback on with the DP??

The parts would be an Invidia DP or an AEM CAI. I am aware of the noise with the CAI, which wouldn't bother me ... I actually would like to hear the turbo spool

I do know that I could get even greater gains with an opensource tune, but for now I'll stick with the conservative Cobb maps.

Thanks.

IMO Downpipe and call it a day, Stock air box flows good enough

Oh yeah, I have read that the stock intake is good for some serious power (pretty sure it was a sticky). I'm just looking for improvements

what you don't want to hear, do them both. The CAI doesn't add a whole lot in that first graph, but after you add the downpipe it will. See if you can find graphs for stg 2 with and without AEM, I bet there is a good change.

I just did my downpipe and got the car tuned, and it made a huge difference.

Yea imo the downpipe should give the bigger gain, but coupled with an intake and proper tuning people are hitting near 300 awhp with a decently modded stg 2. I would also look into a non cobb ots map, such as one from http://www.torquedperformance.com

I'd say get both eventually, but if you had to choose one right now, the DP made a bigger gain for me. I was Stage 1 + AEM and just installed a DP + midpipe + stage 2 reflash this weekend and it's a much more noticeable power increase.

Yeah, I see that I must have deleted the part where I said I would be doing both eventually. Between buying the car, Cobb ap, & window tint ... my funds are drying up I'll be getting the second part come tax time next year

Did you go straight to Stage 2??

Yeah, it looks like the consensus is dp for the most part. I'll definitely look into those maps, thanks

Yeah, I will be buying more starting next tax season

Nice, was yours an opensource or Cobb/Perrin tune.

Thanks for the input guys

I did intake right after my accessport, but it was because it was half the price and I could install it myself (I don't have enough tools to do the downpipe)

If I had the money or I didn't suck at working on my own car, I would have done the downpipe and gone to stage 2. I drove a 2011 with a downpipe and at first off the line it felt disappointing, like it was missing some torque down low, but all that went away on the highway. The chart doesn't do it justice.

I work at a shop & definitely have enough tools to get the dp on So, the dp is more noticeable at highway speeds ... sweet.

I'm running the Cobb OTS maps. Will eventually get protuned if I ever add any more parts.

I didn't notice much of an increase going from S1 + AEM (91 octane) to S2+AEM (91octane). I did notice a huge difference when I filled it with 93 octane and used the Cobb OTS S2+AEM 93 octane map.

i have a short ram and a catless dp. Agency Power. The two of them working together with the tune is awesome. Expensive but well worth the money.
