Hi Brian, until today I never heard of an armytrix exhaust, so I learned something. It was interesting to watch you and Mike work on it, but the fact you two knew what you were doing was incredible. Cars are certainly what you both know. I think I might now understand why it's called an armytrix exhaust. I did hear some difference in the sound of your GT-R. Alright so 7 days a week you upload a new video at 9am? Brian or Mike, can you please review a 2019 Subaru Forester in Limited or Touring trim level. Excellent vid Brian and Mike.

Yeah Armytrix is the brand name. The best exhaust in the game! And being Valvetronic I can make the car loud or quiet with a press of a button. Everyday we have a video at 9am! We can try for a new Forester

Hey man, Amazing video! I got the 2017 model and just decided to do some upgrades to have a louder car. I installed the armytrix cat-back exhaust (mid pipe - valvetronic muffler)... thinking of also changing the downpipes, what do you think? and should i do any additional modifications to have these changes running well?

If I broke a stud, the engine would have to come out! If that happened, I would literally put the car back to stock and sell it..lol

So wouldn't it make sense to just cut the existing down pipe with a saw as close as you can to the bolts. Once you do that you will have much more leverage and access to the bolts. I'm sure your not going to put the old down pipes back. Even if you had to buy used OEM down pipes it's still better than risking to break that bolt at the very top.

I like how you do almost all upgrades on your own, respect! Don't you think it's worth going stage 4.25 (650-670hp)? You have most the upgrades ready for it

Without cats cleaning up the exhaust wouldn't the downstream O2 sensor read the same as the upstream one and therefore cause the ECU to read that as a non-functioning cat and thus throw a code?

Technically. But these downpipes have a bung that just has a tiny hole in it. So the 2nd sensors only get the slightest amount of exhaust gas to them. Plus the tune will turn off cats anyways and adjust the computer to throw no codes.

I think all the downpipe options are about the same. It won't make any difference. But they should all be like 3in or 3.5in

Should I always replace the injectors if I install a catless down pipe on the GTR? Like is it a must? And what are the specifications of the injectors that should be installed in that case?

@BrosFOURRSpeed

10 ай бұрын

It's not a must. However the proper tuning with downpipes will max out the stock injectors. So eventually you'll want to upgrade them. I didn't do them till I went Flex Fuel tho with bigger fuel pumps. So if you stick with 93 youll be good

Yes you need tuning. Deleting the cats without a tune isnt too safe for the turbos. Can risk over boosting. You should get 1050cc fuel injectors as well. Go to AAMcompetition.com and get fuel injectors and a Cobb Accessport. They can send you a stage 3 tune for you car and it'll run perfect. Give them a call!

Im sure you guys couldve broken the bolts free with the break and then used like a power tool to loosen them off all the way just from seeing how much room you had with the extensions nice vid though!

Bay was $100. That was it! I've had the downpipes since last summer. So whatever downpipes you buy, add that cost. And then you'll need a tune and injectors to actually run the straight pipe exhaust. So add $700 tuner and $7 injectors to the bill.
