Hey guys names Abe I drive a 2017 CVT WRX Premium and have recently added some modifications

Recently I drove a manual transmission car for the first time and had a blast and wished that I had got a manual transmission but its too late now. Im hoping to just wait until my lease is over and just grab a New manual STI. Anyways while i have the CVT I hope to make the most out of it, I recently just added the Stillen Cold air intake and I love it, the turbo spool sounds so much better from the inside, I also have a nameless axleback as well but I want to do more. The subaru mechanic I did my intake at said the best way to go is to get Stage 1 AP and Downpipe or Catback exhaust. I just wanted to know what you guys think I should do next, who knows i may just keep this car after the lease. I know its a cvt it was my choice and I want to see what i can do to it as far as modifications. I asked this guy about tuning and he said "i dont tune cvt's" so just an opinion and recommendations please

Modifying CVTs is kind of a bad idea, ESPECIALLY if its a leased car...

The transmissions do not hold any increase in power well at all. Many tuners will stay away from the CVT.

If I were you, I'd stick with the axelback and wait until you get a manual to start doing upgrades.

I didn't think anyone sells a J pipe for the CTV. I think you're stuck at stage 1. BTW why go past stage 1 with a leased vehicle?

Please do your research and read before you mod. That CAI you installed requires a tune to re-calibrate the MAF scaling. By adding this intake and not having the vehicle tuned you are currently doing more harm than good. Either return to stock, or take the car to a tuner and have it tuned for the intake. The AP Stage 1 tune only supports the stock intake and exhaust. The AP Stage 1+SF tune only supports the Cobb Brand RAM intake and stock exhaust. The AP Stage 2+SF map only supports the Cobb intake and most aftermarket high flow catted turbo back exhaust systems.


Furthermore, why would you mod a car that you don't own?

Building on this...the CVT can handle a tune. However, there are torque limitations to be aware of. You should get a pro tune if you changed your intake since the Cobb AP does not cover the Stillen intake. Put your stock intake back on until you can get a good tune. You are potentially risking your motor at this point already. If you're going to go stage 2 (down pipe), then PLEASE research the limitations of the CVT and think about a conservative tune and possibly even an aux trans cooler.

Insert large facepalm here enough to cause a concussion.

Don't worry, OP, We aren't here to bash you into the ground. Rather, we are here to capitalize on your ignorance. :thumbup:

Regardless, you need to do your research on modding the CVT. If you do, you'll soon realize its generally a bad idea to do any power mods (unless you want to take the chance of blowing a $9000 transmission)

When I purchased the CAI I read that the stillen did not need a tune that is why I installed it, if i knew it was going to damage the vehicle i wouldnt have done it. I see you have a cvt what did you do when it came to modding it?

Does anyone know if i could switch the CVT out for a Manual Transmission?
You would spend less time and money selling your car and just buying a manual WRX. I'm not even sure what it would involve, but my best guess is that you'll need a new transmission/center differential, new front axels, new center console, New ecu. I'm sure there are plenty of other things involved that I'm forgetting.

No I mean to take it to the dealer and just switch it out for a manual WRX

I'm not familiar with Stillen intakes on this application, but I have seen only the ETS offering an intake without a tune and actual logs to back it up. It's possible I suppose, but I wouldn't mess with the AFR and not tune it. If it's not doing enough to damage it, then it's not doing anything to benefit it either. If you have an AP, I suggest a couple data logs for peace of mind.

On a side note, can someone take a photo of the MAF sensor location on an FA20F and post the picture here?

If you see a hood up picture it's right next to the air box on the rear left corner.
