SRT FR-S/Subaru BRZ Header Back Performance Exhaust System ... NOW RELEASED!
 

Hello Everyone,
As many of you know we got our hands on the FR-S a couple of weeks ago and have been relentlessly doing a LOT of R&D on what parts we will be making for this particular platform.

We decided to start with by addressing the exhaust system. The first thing we did was remove the entire system to study the factory design and then figure out what improvements we needed to make.
At the same time we also decided to put in an O2 bung before the primary catalytic converter (pic #'s 2,3) so we could collect un-manipulated A/F numbers from the vehicle. This is VERY important data and gives us some very crucial data that is absolutely needed when one plans on make numerous parts that will have to perform and at the same time be safe for the vehicle. At the same time provides us with data that will tell us what works well with the stock ecu. The data collected will also help us in the future when it comes to tuning the vehicle.

Well here are some preliminary pics of the exhaust system. This system starts at the flange right off the "over" pipe and all the way back. We are using a full stainless steel construction and like all our exhausts and turbo manifolds we make this system will also come with a full lifetime warranty.

As you will see in the pics our system is a truly unique design for this platform. We have kept the number of bends to a minimum and at the same time we use a proper merge collector for the rear section to divide the exhaust flow to both sides equally. This particular design was our 5th design and was the most appealing visually and the sound was exactly where we wanted it to be (videos will be up later along with dyno numbers). The sound has a very nice deep tone/growl at initial throttle in from idle to about 3000 rpm then it actually starts to quiet down with more throttle input all the way to redline so as not to attract attention when one is doing some spirited driving ;)

Well enjoy these pics and we will be posting more pics and videos as they become available. Thanks.

Here is another video that just finished processing.

This is done in our parking lot, sorry for the noisy AC compressors across the parking lot (you can see them, it was extremely hot about 100*). More videos of driveby's and cruising as well as inside/interior cruising coming as soon as this slow pc finishes processing. BTW all the videos are done in 1080P HD resolution with HD sound for best replication and for your viewing pleasure. Enjoy!!!

All I can say is -Wow. If there was ever an OEM+ option for the FRS/BRZ this is it right here. Subscribed.

That is very clean looking. NIce.

Now we need vids.

Take off mild, take off full, and drive-by. Interior video of cabin noise too.

Weights would be nice to know too.

Yes this is exactly the look i was hoping someone would develop!!!! Keep the Updates coming :D

Thank you, we appreciate it.

Yes, we will have all the vids and dyno etc. up by this weekend. Including weight numbers and all the pertinent details.

I love that design for the Y pipe going to the mufflers. Very clean and keeps all the components up inside the body and gives plenty of clearance for an underbody diffuser. Very nicely done!

Dynos!

Any chance of making a "catback" version (connecting at the downpipe)

That is quite nice.

me gusta! o_o

Really clean looking system! Should have some good flow, very little bends.

Sign me up (pending videos and dynos)! Any estimation of cost?

wow! thats nice!! sound test please.

Can't wait to see some in-car driving vids, and dyno vids. MAAAAAD

Yes sir, that's what we were aiming for.

Yes we also have an over pipe to replace the oem, but that piece will be optional to keep cost for us as well as for the customers down.

That was the whole premise to the design, not to mention keep the rear aesthetics as symmetrical and appealing as possible.

The final cost figures have not been finalized as of yet, we will post another topic discussing the pricing at the appropriate classified section once we have the final numbers. However, let's put it this way, it is significantly less expensive than anything that is currently available. ;)

size of piping?

Cannot wait to hear this on the street in a video

Looking GREAT !!!

Can't wait to hear it ROAR and see what gains !

Thank you!!

wow finally someone steps up and goes against the stock design. IDK why so many aftermarket companies are simply making replica OEM style exhausts...You can tell by looking at this exhaust it will flow better than stock...

+1 for clips of it under load

I'm imagining that this will be much lighter than the stock setup. If it sounds as great as it looks, you will have my money (provided I can get my BRZ lol).

Long time lurker signed up to ask 2 things

1- will this clear a 1 peice driveshaft whenever one is developed
2 - is that mufflers or resonators -- many tracks want mufflersaround here to stay under 98db

Best looking exhaust I've seen so far.. Tips are perfect in size too

2.5"

TY sir, we strive to be original and at the same time make some of the best parts in the industry.

Yes I just updated post number 2 with the weights of ours vs. OEM. A weight savings of a whopping 20.7 lbs!

I guess welcome aboard :)
1) Maybe it will really depend on the DS tubing OD, however, just keep in mind there are several reasons that an OE will do two piece DS design rather than a single piece, you have to consider harmonics, related to length, diameter, and thickness of DS tubing used. In other words a single piece DS is not necessarily better than a 2 piece DS.
2) Kind of in between not really resonators nor really mufflers. This exhaust is no where near 98db, it really is not loud at all. We will post video clips soon. There is absolutely no drone inside the cabin and the exhaust sound levels under WOT is actually less prevalent than the intake sound inside the cabin in the higher RPM Range. :thumbup:

Is this a yes, there's a catback version that keeps all the original cats so that it would be legal for SCCA stock?

Will you be developing a version with a high flow cat? This would be what I'm looking for.

Negative, if you are looking for an exhaust that keeps the auxiliary cat in place then no that is not standard issue with this particular system.
However, we can and will install a high flow metallic core cat in the OE location for those of you that would like to get one in there, of course that is an optional item that will have additional cost with it.
Please keep in mind that the actual primary cat is still in the vehicle, the primary cat is built into the header system.

See above ^^ reply.


PS. Post number 2 has been updated with some pics as well as weight figures.

Wow, that exhaust looks beautiful! Do you know if the car will have a problem with emissions with just the primary cat.?

Ah bummer, thought it looked nice but can't use it :/

Love it, can't wait to hear how it sounds

I love the look of the system, and am really looking forward to seeing numbers and vids on it.

I'm really looking for something that can pass emissions in California, as well, however. Is this system 50 state street legal, or is it primarily designed for track events/states with less stringent requirements?

So far this looks like the best designed and most thought out exhaust yet. Very minimal bend angles.

To be "officially legal" you cannot touch anything from the air filter to the last cat.

You can get away with aftermarket cats, if they are covered by a heat shield, or it's a place they cannot see too easily.

You can away with just the primary cat, since there is no O2 sensor checking for the 2nd one. If the smog guys don't peak under and look for the 2nd one.

My plan is to run a header that retains the primary cat with a metal heat shield (I will make one if I have too). Then run a cat'd DP. I may try and fab up mounting for the 2nd cat heatshields if I find it's needed for a more stock look.

B E A utiful! that is a good looking design. Will wait to see numbers, and hear exhaust note!

Looks great. Cant wait to see dynos and videos.

Per this site, I'm not sure if that's completely accurate:

Right, if they get CARB EO.

No mfg is going to get away with getting a CARB EO for something that messes with the stock cats.

Intakes.. sure.

Ever since they came up with the revised catalytic converter laws, you pretty much need OEM on modern cars until it is 7 + years old.

Hey, I can dream, can't I? :(

Also, when I said "get away with" I did not mean it was exactly legal :happy0180:

It should pass emissions in all states except the "Peoples Republic of Californication"

Of course you can, why would you not be able to?

Symbiont, uspspro unfortunately with CA 99.99 % of aftermarket parts are not legal unless they are CARB EO cert'ed.

People in CA can use it.. just swap it out for a couple of hours every 2 years :)
