If you are having her tuned, downpipe. Is that a 15 STi, or winged WRX? Have a build journal?

 

Winged wrx....ordering P&L tbe ....current mods kn drop in and cobb ap

 

Get the down pipe, that will make the biggest improvement in power and torque. I would get a catted down pipe mine is a Cobb it sounds awesome. Can't hurt to check out your air intake options either. If you have the means a bigger TMIC, I'm getting a Process West for my 2013. That and a downpipe and you will see some nice gains in WHP & TQ. Take lots of pics and keep us posted on your progress.

 

Looking forward to the results! Post your dynos, and more pics!

 

Ya...not a lot of options on intake for the 2015s and at 400 bucks don't know of mishimoto is worth it....

 

APM tuned just made an intake for the 2015 wrx. I test fit it on my car along with their front pipe. Not sure if it's for sale on their website yet but you can always give them a call. Their sales manager is Mark. He can hook you up! I would assume that it would be less than $400 given their intake for the GR is under $200 from what I can remember

 

Also forgot I got kosei k4r s

 

What's the benefit of a upgraded tmic? Avo has one out for the 15 Rex

 

Better cooling, more air flow. I don't think a top mount needs a tune but it is recommended for the most performance gains

 

intake turb-back exhaust , TMIC , mishi radiator, hybrid bpv, i think thats everything that u can get for 2015 lol

 

Like that it's a one piece system but will be sucking in hot air without a box

 

I forgot to mention they are going to make a box/heat shield

 

In that case interested

 

Im waiting on my 15 wrx to come in and im reading up on as many mods as I can. Do you think the p&l exhaust is worth it? the price is like its made of gold. kind of ridiculous but I haven't seen many other companies making the catted downpipes yet. Also does anyone know if there is going to be a problem with boost creep on these cars like the other 08+ wrxs had?

 

Paid 600 shipped....same price range as others but they include much more hardware

 

Beastmode- I believe ETS, and nameless performance both have their catted down pipes for sale. Once gain, check out APM tuned as their front pipe is about to hit production, they have them for sale on their website. The front pipe replaces the section right behind our first cat. One of the reasons to keep your stock o2 housing/cat is it's believed that the stock unit also functions as a partial collector, much like Diesel engines.

 

Was gonna go nameless but 6-8 weeks out....I will post my TBE results in 2 weeks

 

you dont need to tune for a TBE. if you are going to tune, you should get something that needs to be tuned for. I.E.- downpipe, headers, uppipe, EWG, TMIC, FMIC, injectors and so on...

 

Turbo back exhaust includes downpipe so it needs a tune. Cbe doesnt

 

would like to alter the exhaust note on my 15 Rex Ltd 6mt sts. what are choices, and trade offs?

Thanx. ( newbie when it comes to mods)

Mike

 

Cheapest route would be going with an axle back, I am assuming you are wanting it louder?

 

any recommendation for an AXLE BACK exhaust for increased tone on 15 WRX.. 6mt

 

Nameless, with muffler delete.

 

Just pay a shop to do a muffler delete... cheap and no wait time. ...or invidia catback

 

am I correct in saying because I didn't f with the intake there should be no change in performance or need for tune?

 

Correct. Only downpipe and intake needs a tune as far as those smaller mods go. An axle and catback don't require tunes

 

Nameless has a TBE bundle i believe. I have also seen only (1) one staged performance kit so far. It cost around $2300 and it comes with a TBE and a Cobb AP. I just don't remember the name right now i would have to do research again. But mishimoto has a lot of things coming out. I saw on there blog they added there intake w/ box set-up and a cat-back exhaust on stock tune. The car went up 44 whp and 33 wtrq on a stock tune after the car ran 120 miles and the ECU re-adjusted. I think that is awesome (if true) and shows the potential of this motor. I firmly believe if do these listed mods and tune accordingly i feel 325 WHP easily.

Accessport w/ stage 2 OTS tune or custom tune
Any turbo-back exhaust
Intake w/ box
Upgraded intercooler
lightweight crank pulley

Mind you these are just the available mods currently, upgrade the header/cross over pipe, electronic boost controller with external wastegate set-up and i feel the power capabilities will be booming. Ford is releasing there new Focus RS soon and sources indicate AWD with 350HP from a 2.3 ecoboost 4-banger. So aftermarket support better kick it up or Subaru better crank up the power from factory.

I think they said something similar about the new gti a year or 2 ago

 

wow. no way ford will come out with something that good haha

 

Yeah that was also my understanding. However, more recently Junior (who tunes at P&L) and others have said they are seeing the fueling hit a wall while tuning stage 2 FA20 with anything more than E60. Since E85 requires 33% more fuel flow for stoich, I'm not sure the initial estimates are correct.

 

Pump gas not e85

 

I know. E85 has 33% less energy density than pump gas. If fueling is hitting wall with E60, then stage 2 with pump would be about 66% of the injector overhead.

 

if you don't have emissions get a catless dp more power and will really open that subie rumble!!

 

The 2015 WRX is quite different
