Depends on your tuner I have mtune he will only tune downpipe and intake with a wideband sensor connected to the ecu on stock fuel system maperformance sells a stage 2 tune if you use their intake and downpipe most people will say it leans out
Bro hopefully I can tell you this before its too late. My friend said it the best way possible. With a Subaru.. you need to know exactly what you are doing. Always use a respected tuner and consult before doing anything.
@@whoischris28 that’s where I’m confused going stage 2 soon with a reputable tuner I’m the Subaru community and from my understanding it’s not really required not sure what the right answer is tho I always see the yes’s and no’s with these type of questions I just want the right answers
Sounds amazing need to change mine as well is there a way of testing them to see if they're going bad ?
been waiting 1 month now for grimmspeed to get them back in stock... smh. What catted downpipe are you running??
That stinks but in my opinion worth the wait and Cobb
If I get this for my stock 2020 sti will I be able to hear the flutter or do I have to have an intake
Need an intake and tune
New to STI’s after switching from Fa20 wrx is it safe to run a intake and downpipe i heard yes and no’s a lot

Don't run an intake and downpipe without getting a tune.

no you will need to upgrade the fueling system as well to run both. If you run one or the other alone you dont need to do fuel related mods
