I just recieved the MRT system and it looks great. I'll try to post photos as I begin the retrofit.
For the exhaust group buy folks, be aware that the splitter plate on the MRT system must be
extended 12 mm for VF style turbos. You may want to look into having the splitter plate sized
correctly for the appropriate turbo so no extra welding is needed.

what did you guys pay for this? Is this a Legay specific exhaust or just a
WRX unit that also happnes to fit?
Also, what other GB's are you guys interested in? We are dealers for the
following:
HKS, GReddy, Apex'i, Tein, JIC, Cusco, Mine's, STi, AP racing, BPM and tons

Does anyone have an MRT exhaust system (turbo back) installed on a
turbo? I'm having difficulties with one that I've ordered. It's a
beautiful set but things don't line up.

I think it might have something to do with the age of car - if you have a pre-facelift car (one with sloping headlamps and shorter indicators) - or might just be one exhaust not produced quite right.

One thing which it might be then is a different turbo? If you have a shallower or deeper turbine housing then surely this would put all the hanger positions out by a bit?

Man Larry, I am sorry to hear about your fitment problems. I have the highest respect for MRT and the products they offer, and have had very good feedback from the tech staff on questions I've had. I believe what may be causing your difficulty was something I found during an early communication. Australia is just about as far away from California as you can get and still be on the planet. That makes it difficult to compare what they get with what we get, and I suspect, though our cars are close, they are not identical.
I think the Aussie Legacy came from a manufacturing plant in Japan, whereas ours was manufactured in New Jersey. Australia got the 2.0 single and twin turbo, and we got a 2.2 single turbo. I think The 2.2 turbo is virtually unknown other than in North America (22B doesn't count). Now the 2.0 vs 2.2 engine is not such a big deal cause the block external dimensions are identical. It's the rest of the car and the way the accessories tie in that gives up on us when we start swapping stuff back and forth from overseas. Our safety requirements, and who knows what else ends up giving us a chassis with maybe a little different framework here, underbody metal with a little different shape there, stuff with a slightly different offset etc., you know what I mean?
If you look at a picture of an overseas Legacy or Imprezza engine bay stuff is just not quite the same. And little teeny differences, that won't show up till you try and fit something only to find a quarter inch misalignment, can be a ball buster. Maybe you just somehow got an exhaust for an Imprezza or a late model Legacy instead of the one you need, and everything will work out ok, I hope so. It would be really encouraging to me if there is exactly what you need available, cause fear of those little differences is why I have been holding out for someone building specifically for my USA version Turbo Legacy.
Keep us in the info loop and good luck.

MRT Exhaust System
Thanks for the support Larry/everyone else that has
been e-mailing me regarding this fitment issue.
I think that the differences between our US cars and
the Japanese/Australian/restoftheworld is very subtle
but very distinct as the market demands and the
regulatory issues really breed different machines;
although in appearence they seem identical. (For some
reason, I always thought the turbo cars were from
Japan, unlike the LS and such).
First off, I must say that Brett and MRT make fine
products and their customer attention has been great.
I am in no way going to berate them as they seem
genuinly interested in our US market and interested
in the customers product. I like the MRT products and
the way Brett is a part of the process. They have a
class operation.
As far as the exhaust system goes, the problem seems
to be with the pipe between the turbo and the center
pipe. It seems like it should fit except the catalitic
converter needs to be rotated 90 degrees along its
axis of pipe that it sits on in order to fit between
the side of the transmission and the side of the
tunnel (perhaps this present position works on the
japanese/australian versions-right hand drive?). As
the down pipe begins it horizontal section, there
needs to a slight tweek in the bend towards the
centerline of the car, to give greater clearence to
the crossmember. The turbo mating flange was made too
stout to fit into the space where it should bolt to
the turbo, but alittle grinding between the lower two
bolt holes give it enough clearence to fit against the
turbo mating surface. (you also have to remove the
studs that are in the turbo housing to slide the
collector against the turbo mating surface. Just these
little refinments would make the piece fit in better.
As it is, I think that this could be made to fit. But
not by me. The collector is a work of art. The stock
flange is a flat piece of metal that has a hole in it
the slightly larger than the turbine. The rest of the
flange is closed off! Imagine if you were to open you
hand flat and place fifty cent piece on your palm,
that is what the stock exhaust flange looks like-the
fifty cent piece is the oriface that the exhaust
passes through and the rest of your hand is blocking
off the exhaust side of the turbo housing. The MRT
collector has an opening on its flange that is the
same size as the turbo housing (the whole hand!) with
a splitter plate that keeps the two exhaust areas
seperate and is much larger.
So now I have purchased a new cat converter in hopes
of replacing the one on the MRT front pipe. It is 3"
in and out, a high flow unit that has all the
dimentions to fit properly. I just have to find
someone who wants to weld this up and fit it together.
I ran into a problem with a shop today. This shop says
that they will not perform any work on the car because
in fitting the new cat converter and exhaust system, I
would be "altering the emissions system that was
manufactured with the car". Apparently the shop thinks
that the stock emissions system has a pre-catalitic
converter and a catalitic converter under the car. I
would be replacing the two converters with one
converter and a resonator. That guy doesnt want to
loose his license and won't do the work.
I asked Brett what my options were. I haven't heard
back yet.
I'll keep you (all) posted.
Thanks everyone,

Let us cut to the chase here. Brett, if you are there, can you tell us whether you have any dyno figures for your exhausts on an RS Turbo? That is, on a stock car with the only mod being your exhaust. Can you give us the power figures with all of the variations, i.e straight through muffler with/without resonator ; baffled muffler with/without resonator muffler cat back/turbo back/muffler only? Does anyone else here want to know? What happens to fuel economy/torque/spool up time/lag/power?

I have a Liberty RS Turbo and am also considering getting an MRT system
from my local supplier (S+J) but may just opt for the muffler/rear
section because:
- it's the only bit that's knackered AFAIK
- many people have said the most gain is from the muffler
so yes, I'd be interested in some figures too if they're available.
Thanks, Nick

Nick,
the rear muffler is only part of the restriction in the system. The turbo outlet flange on the downpipe is probably as, if not more, restrictive than the muffler..then there is the smaller dia piping......see the link below, there are pictures of the std rear muffler cut open and the std downpipe flange....(the rear muffler picture is from a wrx muffler, I cut my RS Liberty muffler open and is actually more restrictive than the wrx one shown)
I have fitted the full 3" MRT turbo back system with centre resonator and single outlet rear muffler (meant to be quieter than the twin outlet) and fits excellent and definitely made a difference to turbo spool up and power. Add to this mod the air filter inlet and the car boost is much better. In fact it boosted too easy and the ecu had trouble dragging the boost down after it spiked at 15psi... eventually it learned this an it kept it at std boost. I fitted a chip and now I get 17psi boost at 3000rpm - 5th gear on freeway up slight incline.
cheers, Rod ... in oz

MRT Exhaust system
Yeah I know Rod, thanks.
This topic seems to be a real can of worms. As I said some people think
the most benefit is from the section after the dump pipe, which may or
may not include a hi flow cat and a resonator, while others disagree.
WRXSA had a dyno day recently and one WRX with just a cat back system
dynoed 12-13kw higher than std WRXs, and a couple higher than some with
full 3" systems incl dump pipes. I reckon these results could easily be
different on a different day and are also quite brand dependant. There
is also the argument of outright power vs spool up and throttle response
etc.
For me though, money is the decider. My std muffler is shot and I need
to replace it but I can't afford a full setup. It's also a wagon, ie a
family truckster which regularly ferries the wife and kids about, so
however tempting it is, a loud zorst to me seems a bit out of place. I
also kinda like the 'sleeper' aspect as well.
If I go aftermarket for the muffler, I've basically decided on MRT as
the manufacturer, so I thought any real data they might have on which
part of their setup yields most gain would be interesting.
I'm also interested in your comparison of the Liberty RS vs WRX
mufflers, particularly as you actually disected yours. General consensus
here was that the WRX muffler was no better than the Liberty but perhaps
not. As so many Rexers ditch their factory mufflers in near new
condition in favour of louder aftermarket ones, I can get one fitted for
a fraction of the cost of a new MRT or Subaru item.
Thanks for the link also.

nick,
FYI I also cut open a MY01 rear muffler and this is easily the least restrictive of the lot...this would suit your need better than the earlier models... I got it from MRT for $50 as the rear pipe was cut off i.e. muffler only..... an exhaust shop could easily fit this for around $80. Are you in Sydney? You can have the extra one I got lying around.... for 'nix' .... only has one chrome ext though - also off a MY01.

MRT Exhaust system
Subject: [BC-BFLegacyWorks] MRT Exhaust system
Let us cut to the chase here. Brett, if you are there, can you tell us whether you have any dyno figures for your exhausts on an RS Turbo?
[Brett ] yes we do have the figures but we don't release this data
Now for all the sceptics this is not because we are afraid of it not being good enough, its because in the past if we released the data some other person or workshop would always say they can do better, when in reality they didn't or DID at the sacrifice of torque or excessive noise
That is, on a stock car with the only mod being your exhaust. Can you give us the power figures with all of the variations, i.e straight through muffler with/without resonator ;
[Brett ] the centre resonator will not effect power, only cost!
but it does make it nice to drive on the freeway!
baffled muffler with/without resonator muffler cat back/turbo back/muffler only? Does anyone else here want to know? What happens to fuel economy/torque/spool up time/lag/power?
[Brett ] typically fuel economy IMPROVES
re turbo spool up times are IMPROVED as well
