Okay, heres the deal.
What would your perfect scooby exhaust be like?
Im just trying to get an idea here as to what people look for when it comes to an exhaust system for their Subaru and quite importantly the back box design.
Please can you post what you feel is most important to you in a system,
How you think the rear box should look?
How loud it should be?
Tip style: slash cut, outward rolled, inward rolled, angled exit, straight exit, jap style or rally style?
Tip dia: 3", 3.5", 4" or 4.5"?
Do you use your car for street or track?

Like mine.

In no particular order. Good fit, quality materials, the right sound & must not strangle the engine
How you think the rear box should look?
Tip style: slash cut, outward rolled, inward rolled, angled exit, straight exit, jap style or rally style?
Tip dia: 3", 3.5", 4" or 4.5"?
Single round inward rolled, straight exit, rally style, 3.5" & plain polished (not titanium or carbon etc)
How loud it should be?
Loud at tick over & on boost but not droning for motorway cruising
Do you use your car for street or track?
You missed out shopping but I guess "street" covers that.

As FE, Single round inward rolled, straight exit, rally style, 3.5" & plain polished.
How loud it should be?
No louder than required to get the maximum output, and obviously under the db limit set at most circuits, they vary but typically;
Static 0.5m at 3/4 revs = 101 dB (A) and Secondly, and more significantly, drive-by noise limits measured at 20 metres, hard accelerating at over 60 mph (start finish straight), must not exceed 87 dB(A)

The exhaust on my old Scoob is my perfect exhaust
HKS unequal length headers including uppipe, H&S 3"downpipe with 2 1/2" reducer, H&S centre, H&S Jap spec 4" back box.
All polished stainless steel.
The system is as straight as possble for maximum gas flow, though if anything, I would prefer a 3" system, which I think would suit the EJ25 better

I personally went for 4" Jap style, mainly because Ian at H&S did a blinding deal on it.
How loud it should be?
I am now starting to lean towards your idea of a quieter exhaust (and I mean a lot quieter than it is now), it does pain me, when you get to a track day, to wonder whether you are going to be pulled from the track or not ....... I have a bung, but that just strangles the engine.
Do you use your car for street or track?
Both (occasionally)

Difficult one this, quiet when driving at motorway speeds, quiet for a track but noisy for a cruise - doesn't help much I appreciate
inward rolled straight exit. I wasn't keen on the idea for a downward facing exhaust......
Whatever gives the best flow I suppose
I'm not getting the exhaust, what are you using yours for? museum piece at Zaks if the last 6 months are anything to go by

The Blitz NUR Spec ticked all the boxes for me for street use.
The alternative for me if I was ever to change or wanted to be a serious track user would be something like the STi Genome box.
I have seen one without the colouring (polished off I believe) and I think it looks great. The sound is pretty good too, not too droney (sp?) but sounds nice on WOT!

if you could design something half as good frayz you'll be onto a winner
to answer you post:-
got to be round can and pipe. done to death, but it's the only way for a marketable product.
middle of the road loud. not quiet like a prodrive system, but not loud like a blitz. a few too many strict trackday regs nowadays.
straight exit
4" max. just get the feeling people are going to get bored with a drainpipe sticking out the back sooner or later.
all based on if you want to sell a product rather than a one off one your own car by the way

Please can you post what you feel is most important to you in a system,
How you think the rear box should look?
Plain and Simple design Cylindrical Back box with round tail
How loud it should be?
Quiet at idle, throaty when blipping the throttle....
Tip style: slash cut, outward rolled, inward rolled, angled exit, straight exit, jap style or rally style?
Round rolled inward, straight angle
Tip dia: 3", 3.5", 4" or 4.5"?
3.5, 4 max (about 10 for tunnel run?)

Frayz,
Does this mean that Primary Designs are looking at making an off the shelf system?
Please can you post what you feel is most important to you in a system,
1.Performance gain. 2.Sound. 3.Quality. 4.Price.
How you think the rear box should look?
I prefer a slightly duller finish, I don't like the highly polished look.
How loud it should be?
100dB at 4.5k. I like the sound from unequal headers, but don't want a boomy exhaust at 70-80mph.
Tip style: slash cut, outward rolled, inward rolled, angled exit, straight exit, jap style or rally style?
Inward rolled.
Tip dia: 3", 3.5", 4" or 4.5"?
4"
Do you use your car for street or track?
Street with a planned trip to the Ring (if I ever get time off work!)
And one question I think you missed. High flow Cat. I can't be arsed with any hassle from the cops or come MOT time.
Hope this helps!
