- After removing the smog pump and having the exhaust out, it was the perfect time for an upgrade.
This is the up-pipe: amzn.to/2y3UveV
This is the downpipe: amzn.to/2KL44ly

This is installing an Invidia up-pipe and catless downpipe that has had a high flow cat added. the main reason for this is that the factory exhaust was rusting out and leaking.
Good content. Links to parts etc used in your vids would be super helpful👍🏾
I will work on that, Thanks for the input.
Is that up pipe catted?? 06+ should have been no cat since the Secondary AP system.
No, there is no cat in the up pipe that came off or went on.
did you have to change also the up pipes , or just with the down pipe was enough, Did you have clearance issues with the Auto Transmission ? I being told that it could happend. I have a 2007 XT A/T just like yours.
I did not have to change the up pipe to do this. There were no clearance issues with the transmission either.
I change the exhaust with a "Turbo" SS pipe. If I change the down pipe, do I have to tune the engine, like you mentioned with Stage II ??
You should be fine swapping the exhaust without a tune. If you swap out the intake, then you would want to as anything on the intake side will have a greater impact on performance.
@@DIYEVERYTHING Thank you for your answer. What I look for is more efficiency. free a restricted engine from factory, so I installed a K&N air filter (original) type and a "free" flow exhaust ( Turbo SS) mid pipe, but in order to "complete" the idea, have to change the down pipe, which what I'm going to do... Envidia? My XT is for normal street city driving, I just like to make a "better" standard Forester, better brakes (EBC ventilated, perforated and slots), KYB with Swiff , 225-55/17 Toyo TR1 tires and a exhaust system. Thank you for your interest. keep on with your mods.
would this fit onto an 04 jdm xt, its an ej20 as oppose to the audm/usdm xt ej25, it's got a tf035 as oppose to the td04 also
I can't say for sure, I don't have experience with the jdm engines.
Just to check if I got this right because i plan to do this on mu FXT - factory downpipe has a small cat inside than you have a main cat after. Downpipe you installed has only one cat, somewhere where the factory main cat is located? So you basically let you car breaths or to be precise farths :) easier, but did you have problem from lambda probe switching check engine lamp?
Older models had a cat and temp sensor in the up pipe that could break apart and destroy the turbo. Subaru eliminated that with the facelift (SG9) from 06+ models. The factory down pipe (J pipe) has 2 small cats, one before and one after the O2 sensor. I eliminated the one before the O2 and added a high flow cat after the o2 sensor. The only reason I added the cat back into the system was for "emissions" and to prevent boost creep. I never had an issue with the cel coming on after this modification. I also had a pro tune within a month after, so it may have never had the chance to come on before the values were altered.
@@DIYEVERYTHING Thanks for reply. I have an SG9 and I plan to do something as you - i am building a belmouth downpipe without the cat and I will keep the second cat. I am just wondering because lambda is between the cats. I am not worried about CEL it is easily eliminated but my concern is more towards if the second lambda data could lead to lean mixture. One idea is to move the lambda behind the second cat.
I monitor my afr and under normal load it stays at the 14.1 to 14.3 range which is normal.
Unfortunately the hyperlinks no longer work. Which dump pipe did you use for this install?......I was under the impression the Invidia dump contacts the steering knuckle on lock requiring a small dent to be added into the dump to provide clearance ???
If your down pipe contacts the steering knuckle then you're doing something wrong. There's a good 6 to 8 inches between components.
@@DIYEVERYTHING In Australia the steering wheel and steering rack are on the right hand side. There is a contact issue with the steering knuckle requiring a small 5mm indentation t on the right hand side of the bell-mouth to provide clearance. This is when using the WRX dump. In Australia Invidia dont make a dedicated Foz dump.
@@dronedownunder652 Ok, I'm not in Australia so your application will be different.
Would this downpipe fit on the 2004-7 Forester?
yes, I believe 04 to 08 fxt, 02 to 07 sti and 04 to 08 wrx.
@@DIYEVERYTHING yes what he said
Kinda thought all the swappable parts from forester was 04 to 07. But only 04 sti calipers work on a 04 fxt hmm
@@jerstolp1 The SG body was 04 to 08. The reason a lot of the 04 STI parts are a direct swap is that they ran a 5X100 wheel and shared the same type of strut mounts. But things like the steering rack, for example, your best to get from an 05 to 07 STI rack. There are a lot of parts from different years that fit and a lot that don't but it's fun to learn and experiment with.
Have you still got the TD04 turbo installed? Just wanting to know if this is a worthwhile upgrade with the TD04. Cheers!
You are on the right track, new video on my turbo out April 30, 2020
It's worth it to get rid of the up pipe with cat which is restrictive.. Bout 10 hp or so lil faster spool.. Not that the fxt needs that on td04 lol.. But biggest part is getting that car outta there so it done eventually break up n go into you're turbo
If u have 1 without a cat allready I wouldn't worry. Not until ur going 4 big numbers or wanna run a ewg... Psssh fun
Bellmouth is 4"
Yes, but they aren't sold based on the size of the bellmouth, They are sold and described by the size of the pipe that mates to the exhaust pipe and not to the turbo.
@@DIYEVERYTHING I know I was just joking about
How loud would this be going down the highway/interstate? So like 65 and 80 (for about 6hrs).
That's more about the actual muffler than the up-pipe and downpipe. However, on the stock exhaust it was still pretty quiet but you could really hear the turbo spool which i like.
@@DIYEVERYTHING ah ok that's nice then, since I don't want the drone and all that. I'll leave the being loud with my rx7
