I don't think it would cost anything like £500 for some lengths of stainless tube, a bit of sheet to roll into a can, a tailpipe and some
perforated tube, so materials cost wouldn't be that high, but, the cost comes when someone bends a bit of pipe into a
"primary" and then adds 300% to the cost of the actual pipe.
Depends who's doing it really, keep us posted!
We had one done by these guys: LINKwho apparently made the mclaren f1 exhausts.
That was in 96 and it cost £900 for a turbo back system on a saph cos, but, there was a £650 power cat in there. Cats were dear back in the day, the
system was cheap enough really.

It depends whether they;re doing that or actually designing you an exhaust system to suit your setup....

But unless it's going on the dyno over and again, with different length headers /collectors etc, to tune for your required power/torque
charecteristic, all they are doing is making it fit, albeit to a set length perhaps, that was discovered by someone elses previous dyno work, but the
work isn't theirs to do. Theres no science to it, but there is quality craftsmanship. If you get what I mean.

... I remember the days when I used to think that you could get something like this made for under £500! Oh how my eyes have been opened!
If you're paying VAT, then I reckon it'll be over the £1k mark (hopefully not by much).

Cost a little under £600 (not including silencer), made by Exhausts By Design.
I can't compare it to any other system performance wise, but the car made 121bhp at the wheels on the rollers at Big CC with nothing but the
exhaust, pipercross sausage filter and dynojet kit, so it certainly can't be doing any harm

Turbo back so one pipe to make all the way back. This setup has 6 primaties to fabricate so I would certainly expect the majority of the labour cost
to go here.

The costs comes in the nature of the bends, not quite an off the shelf 45 to a 135 degree job. The add 300% bit might be right if you could picture
how tight it is in there and the fact that its being done while keeping to a design spec. Well obvioulsy not 300% but with exhausts you do get what
you pay for. I intended to do no tuning at all to my engine so having a good exhaust design is vital to keep it operating like it was. It would have
been much easier to say I want you to join those 6 outlets into one. A turbo would make things easier but I don't need 600bhp or afford the
extra expense! 1bhp per kg would be fun though I guess

looks wise i am really not liking the way that one primary runs 
just looks wrong to me although sure its great for flow just astheticly it lets a otherwise stunning system down

Thats a point, any ideas on how the side panel is going to fit? Is it going to have to be split?

Is that hot or cold drawn? If hot drawn I suspect primaries cost circa £900 and the silencer £250 so I stick with my guess of £1200.
If cold Drawn then £1000 ish
Let us know.......... Neil

Just cut a hole and slide it along, already worked that bit out. Not that big a hole. That curved one looks nice in the flesh, its just that its
got the shortest run of all so something had to be done and the steering shaft passes through the middle of them all

over 50% of voters would pay the cost Chuffed isn't the word. I had quotes of £1500+ for the same thing! Can't see how it could be
done better with the space and spec

I never said i'd pay the cost - just what i thought it would cost.
Slightly nervous that your exhaust can is a little small.

Over 50% of voters said £800 or less, so was it?
As for the cold v hot drawn thing, I don't get it. The tubing was bought in then bent up in a bender, nothing more.
Are you talking about the raw material manufacturing before it was bought in or how they made the system?

Holy cow that looks nice!!!
Mine is just the standard 6 - 2 manifold with some scrap bits of pipe i had in the garage sticking out the side and going into one of my tintops
silencers! No where near as cool looking as that.
Keep up the good work!
How long can i resist the temptation to drop a V8 in?

yours is a very tidy solution, how have you done the pipe work inside? any pics? It does look cool though, are you going to paint it?
