The Perfect Custom Exhaust
Discussion
A diy build means you get to spec all sorts of dimensions whereas an aftermarket package will be partly tailored towards build cost versus profit.
Diy could work out better in some respects and may be a lot cheaper. A custom build by a specialist will probably cost more but may look better.
OP may want to read some books before he starts cutting up scrap tubing

Why build it yourself when there isn't anyone in this country that knows anything about these cars? I would buy Wortec or Difilippo (I have bought both).
Its nice to be differant i wouldnt say that there isnt anyone that nows about these cars seems to be plenty of people that dont work on the cars themselves alright...and theres only one way to learn and thats to ask and have a go at it..
My point is there aren't that many people good enough to knock up a custom 2.5" - 3" mandrel-bent exhaust. Their welding is shite and they are used to making custom systems for Pug 106s where the tubing is a lot smaller. If you want to spend loads of cash on a bespoke system then great but the cheapest way to get good results is turn to the trusted suppliers.
Ask Roger and he'll say buy Wortec, ask Mark and he'll say buy Difilippo; I doubt either of them can recommend a decent, cost effective alternative; I know, I've asked.

Plenty of good exhaust guys around who specialise in motorsports. A few years ago Simpson Race exhausts quoted me £1800 for a full exhaust headers to tailpipes.
Plus cats and mufflers.
They do awsome work. http://www.simpsonraceexhausts.com/page10.html

To be honest if you have access to the right equipment why not do it yourself? nice smooth bends and no restrictions aren't rocket science - tuning the fecker afterwards is though (to me)
If you start looking into restrictive flow, even the exhaust tips are restrictive, ideally a parabolic outlet causes the least turbulence, so i suppose its all about what Drew needs from his system, without having to pay the premium to the 2 big players in the game......

^ Your comments would seem to imply that UK peeps can't make decent exhausts? We have F1 teams who do a pretty good job and know about specifications. I know one of my customers had an exhaust made for his 427 lsx cobra by a supplier to F1. He didn't need to go abroad to get it made and it's well pukka.
Oz seems to be good for efi and maybe some engine stuff but I've never heard of them being a world leader for exhaust systems.

i didnt say we couldnt make it over here its a cost issue that we dont. not really a skill issue Oz seems to be good for efi and maybe some engine stuff but I've never heard of them being a world leader for exhaust systems.

Obviously it will cost more than something that is produced in quantity, but thats the nature of all such things.
I had custom exhaust manifolds made for mine, the price was fair, and the quality superb, made by OJZ Engineering.
Of course there are also a lot of butchers out there, who build poor quality stuff, but there are some top fabricaters out there.

circa £1300
That might sound expensive, but for a custom built set, merge collectors, which were fabbed without seeing my car, its pretty damn good.
I sent them my old headers arrgghhh, damn manifolds. Talking like a bloody american !!!
They then built a jig around them to build the new 2" manifolds ( old's were 1 3/4" )
First time around, there were some clearance issues, which required more work when I fitted them to the car.
Second time was no problem. The area around my steering linkage is incredibly tight, so to be fair....they really did a fantastic job considering the car wasnt with them !!
Passenger side fitted no problem, as there is plenty of room there.
My only one complaint, was ground clearance wasnt what I had wanted. But so far, the only time they have grounded, was during a silly moment :P
Compared to a lot of large diameter stainless manifolds from the US....mine arent overly expensive at all.

?? Because 2 grand for an exhaust isnt good money is it! Its hardly a massive sience to stick two bits of 2.5 inch tube from one end to the other. Have you looked under your car? Do you believe there is a great deal of science going on here?wormus said:
