Default strommung cat

Just received my order from Dale at Boxer4racing. Picked up a strommung cat to go with the borla header I picked up a while ago. The box says it is for the 2.5 RS. Just want to know if anyone can confirm that this is the right part for my 01 Legacy GT before I bring it to Meineke to install for me.

Thanks.

is the CAT allready with pipe or just one that u have to weld to pipe.?. when i ordered hi-flow cat from dale it came as bolt-on part.. altough i had some clerace issues with automatic transmissinon cause cat was right under the rear driveshaft instead on side of transmission.. which I ended re-selling it to someone else and using custom made one..

I have borla headers too.. so its direct bolt-on.. borla headers are bent to have all connections in stock places.. and save yourself few bucks and do the install urself.. it probably came with new gaskets and bolts.. just save the bolts that are behind the old cats.. these u will need..

From what I can tell, you are saying this will have issues, right?

It looks like it will fit fine. My uncle and I pulled the cat pipe out of his '01 Legacy last week and busted the cats out (they were disintegrating, and no $$ for a replacement). There are 2 in the stock pipe: one in front and one out the back. In the Stromung setup, the front one is replaced with plain pipe, but the one that is on there is where the rear cat is on the stock piece.

The only issue I could see would be if the heatshield on that piece were larger than stock (and by larger I mean MUCH larger).

I don't have any experience with fitting one of these, but that is my view and opinion on the subject.

it's actually quite small compared to the heatshields on the stock cats.

Thanks, guys. I am hoping that it will be a direct bolt on affair since my BE is M/T. I realize that I can save a few bucks by attempting this install myself; however, I believe I have passed my DIY mode after seven years of putzing around with my DSM. [Two engine rebuilds, clutch jobs, timing belt chages, replacement of all things mechnical, as well as some things electrical, yadda yadda yadda...] :-)

My Subie has 113K miles on it with not even an oil change from my hands and I am thinking some of the bolts may have rusted, seized, or are otherwise unable to be removed with regular tools. With my luck, the unremovable bolt will be the last one left and then I will be stuck with no car until I can figure a way to take off that darn bolt. Last thing I need is to be flat on my back trying to PB a seized exhaust bolt and wasting a whole day on a five minute exercise. LOL.

Next question. I bought the cat since I have been getting the C/E light for bad cat for a VERY long time now and I finally decided it was time to take care of it. Boxer4racing told me that the replacement cat would probably not fix the C/E light problem so I picked up one of the MIL packages. I doubt Meineke would agree to install this "non stock" questionable mod. Any one here put it on? If so, was it fairly easy? And did it fix the dreaded C/E light problem?

Thanks, Legacy experts.

I got the Random cat, which is basically the same thing, and it bolted in with NO problems on my 00 BE 5MT between Borla headers and a Fujitsubo exhaust. I got the part for the 2.5RS, because by all accounts, the BE and RS exhaust differs only in the midpipe length. Also, the Random is a metallic-substrate unit, so it flows better and last longer than brick types. I'm not sure which the Stromung is.

I did get a CEL 3-4 months after the install of the cat, but an ECU reset cleared it. You may have other issues.

Nt sure what brick type means but I would guess it is not as good as the Random Tech. BTW, the pic you showed is a bit different than the Random Tech type sold by Teagues. Wondering if you ever saw this type...



Also, wanted to know if you felt a difference when adding the cat back. I noticed a sotp difference w/ the header and hope to feel still more oomph when the cat is added. Just do not know how much more power can be gained with a catback. I can imagine a throatier rumble, but have not read much about the actual power gains from an aftermarket exhaust.

I believe the stromung is metallic substrate.

I did notice the different picture. Random used to offer a brick-type cat, but later moved to a metallic substrate like the one you show from boxer4racing. Stromung is probably using metallic substrate now, as it's just better.

The cat-back was on the car when I got it. It's not a performance exhaust by any means, as the "Legalis" name of the line suggests it's meant to be quiet. I'm sure it provides more power than stock, but it's probably the power limiter in the exhaust right now. The cat added a little more punch, and helped out the torque from idle to redline. It's not much louder either, probably due to the resonator in the midpipe and conservative muffler.

Cobb has dyno charts for their parts, and I've seen TWE dyno charts as well, over in the NA forums. I wouldn't get worried too much about how much more power you're getting, but rather how much easier the car will be to drive.

To add to this thread: I don't know if there are year-year differences, but I had a hell of a time making one of those Stromung high-flow cat pipes fit properly on my old Leg.

'97 sedan, 5MT, stock exhaust. The location of the cat on the pipe cause it to bang into something- I can't remember what it was, as it was quite some time ago. It was particularly noticeable & noisy upon hard deceleration.

It's possible my motor mounts were getting mushy, and that didn't help the matter, but even still, the cat was jammed right up against something when the car was parked. My solution was to wrap that section with header wrap so that it wouldn't bang/rub/vibrate.

Otherwise, it's a great part. It sounded excellent, and didn't cause me any CEL issues.

I never had a problem with mine, 95 Wagon, 5MT as well. Did you happen to notice where it was rubbing?

My stromung is fairly new, how old was yours?

Please report back on the sound level. I heard the Random Tech is really loud, not sure about the Stromung.

My Random didn't make much difference at all. It added a little raspiness, but much less extra noise than I was expecting. The midpipe and muffler are the places to control the sound after a HFC is installed.

I'll look at that when it's not raining out (it's been a week and a half).

As for sound, I didn't notice that the stromung made too much difference. Maybe a bit louder.

OK. The cat was installed last Saturday. The nice guys at Meineke even installed the MIL to handle any lingering c/e light issues. Cat pipe looks like a pretty good fit - no banging against the underbody. However, the guy who installed it stated that the conical looking gasket that was sent with the pipe by Boxer4racing did not seat all the way. He thinks it may eventually seat since the cat to catback connection has some type of spring set up (perhaps to ensure a tight fit even as the car and hangers wear out). There is a bit of exhaust leak at that point as well as a leak where the borla headers are connected to the block. When they were originally installed I did not have the gaskets and the shop used old gaskets with some RTV. However, there is clearly a bit of a leak at that point, too. Everything is good, BUT the c/e light is still on.:-( I did pick up the header gaskets but it was getting late so he will install them next time (at no charge).

Question: could the small leaks at either the block to header or cat to cat-back parts cause the c/e light?

If not, could the MIL be the cause? The shop pointed out that the instructions described wiring for the WRX. The wire colors were not the same. Still they connected the wires as it made sense (to them). Are there different MIL for Legacy versus WRX? Does anyone know the actual colors of the wires that are connected?

As far the mill isue, i saw someone was selling something that you screw it to the sensor spot on the pipe and you screw ur O2 sensor into that.. supposly limits how much exhaust gauses are going thru sensor and eliminates the CEL..
