what's up everybody it's justin and this is Shelby
today we're going to be changing things
up just a little bit with my exhaust
system on my 2017 subaru brz so as you
can see we got a big ol box here this is
actually a to Tanabe concept G
performance exhaust it's nice and
lightweight it's a single exit exhaust
that exits out of the driver's side of
the car and this time I actually picked
up a cover for the diffuser that
actually plugs the hole on the other
side of the car so we don't have an open
hole with the single exit exhaust now
you're probably wondering why am I
getting rid of the exhaust that I had
just installed on the car about a month
or so ago and I'll tell you why it's a
couple reasons in particular the first
one is the exhaust that I put on there
it's a single exit it's got a larger
magnaflow muffler under the back of the
rear bumper and actually exits out the
passenger side of the car I'll show you
what that looks like here get an idea of
how its laid out now the way the exhaust
was meant to be used for maximum weight
savings we were supposed to drop that
muffler section the larger canister with
the passenger side exit for this small
little shorty muffler which actually
sticks out the driver's side of the car
so this saves even more weight over the
system by itself but it's much louder
and in order to get the maximum weight
savings you have to change out the
exhaust every time you go and race and
I'm kind of lazy I didn't want to do
that to one extra thing I had to do
while at the track or at the autocross
course so I've eliminated that I got the
concept G exhaust it's 22 pounds is pretty
dang lightweight without having to go into a
titanium system or something like that
it's also a single exit it's pretty
quiet from what I've heard it's not obnoxiously
loud and we'll find out and what we're
going to do is unbox this guy show you
what it looks like then get the car up
on the jack stands behind me we'll take
off the old system I'm actually going to
weigh both of the system side by side
see what's the weight differences
are then we'll bolt up the new concept
g exhaust and get some engine sounds
alright so we got the Tanabe Concept G
system unboxed first impressions about
the system is pretty nice actually this
is a really lightweight piece the welds
are good flanges look nicely put
together and even the exhaust hangers if
you guys can see that or not but the
exhaust hangers are hollow getting real
crazy with the weight savings so that's
pretty cool the muffler section also
well built nice and shiny got the cool
Tanabe logo on there and the
medallion logo on the side of the
exhaust tip and of course an extra bag
with the nuts and bolts and gaskets
and that's pretty much it
so it looks pretty good if we're going to
get the car jacked up behind us I'll
pull off the other system we'll weigh them
see how much they weigh what the weight
difference is get this guy bolted up and see how it sounds
okay cars up on the jack stands we're
going to unbolt the old exhaust system
that's like four bolts so it should just
take about five or ten minutes and we'll
weight it up against the other one
so we're going to start weighing these
things will start with the stuff that
just pulled off so the muffler section
will go first here can you read that so 14
pounds for the muffler section will get
another measurement real quick
and even 14 pounds again we'll grab the mid pipe
section so twelve point eight pounds on
that one we'll try one more see if we
get the same here 13.4 pounds and 13.4
pounds again so I think it's safe to say
the midsection for this old pipe is
about thirteen and a half pounds we'll
say 13.5 since I did have one that was over
and another one that was slightly under
so total weight from the old system I just
it just took off twenty seven point five
pounds not too bad probably a few pounds
lighter if we put that shorty pipe on it
but now we're going to weigh up the
tanabe concept g they claim 22 pounds
from the manufacturer for this system so
we'll weigh them up and see what it
comes out to be ok starting off with the
muffler section so i'm showing ten point
six pounds get another reading here ten
point eight pounds so we'll say right
around ten point six or 10.7 for the tanabe
concept g muffler section
alright let's see how much the mid pipe section
weighs here so I got eight point six
pounds on that one will try again eight
point six pounds once again so 8.6 pounds
for the mid pipe alright so not too bad
with the new concepts g-system total
weight from my little scale 19.3 pounds
so a couple pounds lighter than what
they advertise the old system coming in
at 27 and a half
pounds so we're saving over eight pounds
total between my old system and the new
one and the new one is a lot nicer a lot
cleaner made it's got the single straight
exit muffler versus the curve that goes
around to the passenger side of the car
like on the old one so I'm happy about
that a lot cleaner look and we'll be able
to plug that hole on the diffuser side
once we get it installed with the
diffuser hole plug that we bought so
we're going to get this new system
installed see what it looks like and
then we're going to get it outside crank
it up and see what it sounds like
so instead of doing the time-lapse this
time with the install since the concept G
is a system you can go out and buy and
put on your own cars i'll give you a
quick little mini how-to on how you get
this thing installed in the car it's
pretty straightforward pretty simple to
only for nuts and bolts and three
exhaust hangers so we'll get under there
real quick show you what you need to do
and how simple it is so first thing
you're going to see is the concept g mid
pipe just laying out here on the floor
where it's going to go up into the car
and then the muffler section back there
basically the front of the concept g mid
pipe attaches to your front pipe which
is the pipe up here which has your cat
pipe in it it's just four or i'm sorry
two of the spring bolts real simple it's
actually easier to hang this pipe by its
exhaust hanger right down there and that
just goes right up next to the
differential hanging on that exhaust
hanger that you can bolt up the front of
it real quick and easy and the mid pipe
is up and in place try to do a little
bit of a close-up of what it looks like
where it attaches and then the stock
exhaust hanger mount the lighting is not
good but it's right up in there now
taking a look at the muffler section i
took the stock rubber exhaust hangers
off the stock exhaust attach the two of
them to the muffler pipe those exhaust
hangers are going to attach to the stock
exhaust hanger mounts here and here and
then we'll bolt up the muffler pipe to
the mid pipe which is right there and
getting blinded by the light but i'll
get a better shot in a second here
alright so once again I hung
the muffler's section by the hangers
first here and here went in really easy
and the muffler pipe lined up pretty
much perfectly with the mid pipe section
back there as you can see so what you do
next is grab your gasket that came with
the exhaust system and the nuts and
bolts that also came with the exhaust
system slide the gasket up in between
the mid pipe and the exhaust pipe insert
the bolts into the holes attach the nuts
tighten them down and you're pretty much done
alright the Tanabe concept G
system is installed I got to say that
was super easy literally four bolts a
few exhaust hangers in the stock
positions went in super easy and the
fitment is pretty much perfect couldn't
ask for anything better let's take a
look at the underside see what it looks
a little shot of the exhaust tip
i'm already loving the tip and the
fitment on there
going back underneath everything fit flawlessly
so one more piece to this puzzle and
that's getting this empty diffuser hole
covered since we obviously don't have a
dual tip exhaust we've got the open hole
and for the cleaner look we're going to
put the cover on there and see how it checks out
so I've got the diffuser hole
cover here not a very fancy part it'll
probably do the job I look at this as
one of those it looks good from over 10
feet kind of part cause when you get up
close the texture of the diffuser hole
cover doesn't exactly match the texture
of the diffuser itself but it should do
the job make things look a little bit
better at least so we'll get that thing
installed we'll finally get in this car
off the jack stands crank it up and hear
what this new exhaust sounds like
diffuser cover is installed give you a
closer look here
as you can see there is kind of a daylight gap around the edges
it isn't a perfect fit by any means but
but like I said it'll be a good fix for
you know ten foot plus type of look
so I just took the car for a drive around
town with the new tanabe concept g
exhaust and it sounds pretty good i like
it so far doesn't drone too bad on the
highway sounds good going through town
and through the gears so we'll start it
up here outside the garage give you an
idea of what it sounds like a idle and revving
there we go everybody my new Tanabe
concept g exhaust system i'm really
happy with this system on the car i do
like it a lot better than the previous
custom setup that i had the new Tanabe
is a little bit louder but i think it
has a little bit better sound a little
more of a box or rumble coming out of
the engine which I love personally and
on top of that we've saved a little bit
more weight so all in all a good upgrade
I'm going to go ahead and do a slow pan
of the rear of the diffuser so you can
get an idea of what the exhaustive tip looks
like and what the exhaust hole cover
looks like is well on the passenger side
of the car that's going to do it all for
this video everybody i hope you enjoyed
as always leave your thoughts and
comments down below I would love to hear
from you until next time i will talk to
you all later
