How much do you anticipate shipping costs to the UK and Mainland Europe would be?

I should be able to make a very good price on shipping, What is your VAT in UK and europe? And do you pay that when product arrives from out of EC?

17.5 percent and yes, duty is payable on parts from the USA.

let me work on that one a little!
My thoughts With the e21 323i now entering the value range of the restoration market, would be that replacing worn and damaged componwnts with factory like or better pieces. My thoughts are that people with these vehicles are building quality restored cars, with mild upgrades, (engine displacement on a rebuild, etc. 5 speed conversions, etc.) Typically during the vehicles mid life, many get destroyed, altered beyond return, or rust. And the survivors of the era end up being restored better than new. I saw this happen with the BMW 2002.

The 304 as an upgrade is because the original as you see in the photo was mild, and no one wants the maintenance issues of mild steel. There should be not issues joining stainless with mild, since we are bolting them together at the bottom flanges. Temps are very cool at that point. We do this combination on many vehicles without any issues.

Yeah, 1.5mm is fine, thats why I was asking

Normally headers might be as thin as 0.8, so 304 @ 0.8mm would be too brittle, end up cracking in places like merge collectors, etc, so yeah, 1.5 is good.

Probably worth you asking the same question on bimmerforums e21 section, quite a few LHD guys with 323i's there too

Those headers dont have flanges on them, look like they are designed for slip joints.

the header after each merge collector is a slip fit to the next section down pipe. this help with expansion as the individual pieces grow in length during the heat cycle. It also makes for easier installation. Shipping etc. Also keep in mind to adhere to the factory junction points we needed to have the O.E. collection point at the bottom where the resonator is mounted, but yet still have a primary tube long enough for torque. This point would have put the flange connector in a tight spot near the body. So a smaller slip joint was the best choice for the smaller space.

I could buy a full titanium exhaust for the rx7 for the price of this "standard but a litte bit better" effort by supersprint.

Its' a bit costly is this limited run?!

This is bring out tooling after 15 years and making 10 sets. Remember the 323i has a pretty involved exhaust, headers, resonator, and L&R muffler. There are a lot of pieces involved.

Titanium is not a good choice, it makes great conversation because of it's racing application. It's a light weight material, does not like to heat cycle, gets brittle, and if it needs repairs your sending it someplace for a patch. In a race application weight is very critical, and cost plays little role. Parts are discarded when they reach the end of their projected life cycle.

yes but i was comparing the cost. Titanium is very VERY expensive but still cheaper than yours. ill give you that - rx7 exhaust is a bit more simple. but i paid 300 pounds for a full stainless system on my old FC that had twin pipes that went either side and it was fully guaranteed and it was mandrel bent and every weld was beautiful.

you dont even use a mandrel bender? tbh i think your charging too much for a "name" and a "limited run", andfrom the headers back - theres no difference between yours and a stock system!

I could go to a custom builder (not some back street two bit effort, i mean a PROPER! builder), I'd get a mandrel built stainless steel full system front to back thats probably has more performance gains and i'd hazard a guess that it would be about what your asking or cheaper than the 2 grand you want!!

im not insulting you and i can appreciate that you want to make a few sales here - if you wanted advice like you asked for at the start of the thread - i would revisit your prices - seriously dont think you understand that the only reason we own these heaps is because we paid next to nothing for them.

My full system including the manifold for the my m30 converted car came to £1350, all made from 304 stainless, was flowed to insure heat soak was evenly distributed and was a bespoke item at that time... 2k seems a hell of a lot... granted ive owned supersprint on my golfs (mk1/mk2 gti) and they have been very good.. but 2K for a 323i is excessive... unless its 22k gold plated.

i got my full stainless steel exhaust, and bare in mind 6 branch middle box and 2 back boxes for a staggering sum of 480 pounds. and is sweet as Willy Wankers chocolates!!

Im with Nas on this, price is proper f*** for sale.... cant see anyone forking out that kinda squid for a bit of stainless with supersprint stamped all over it... good idea but the price os totally wrong...

www.christullettexhausts.com built me a bespoke system for a fraction of the price quoted here.

I had a FULL system built, including down pipes for £600 and it is simply awesome !!!!!!!! The best investment i have made on my E21

O.K. guys dont hold anything back! Speak your mind, I sense some of you are wanting to really release some frustration. Just keep in mind before you run me through the meat grinder, that the e21 is my favorite body style, and I'm a real fan of that car. and Supersprint spent quite some time to find all these jigs, because of my request.

And yes all Supersprint product is mandrel bent. We dont even have a conventional tubing bender at the factory.
The only savings, I could see happening is to cut the freight cost to the US and ship directly to the UK, if that is where you are located? So figure at best about 10% difference.

As far as your custom exhaust systems, that you're speaking of, I have no idea what they look like? And not everyone has the luxury of good fabricator near by. If these are all custom systems for one car, then jigs were not built to duplicate the systems.
My offering was to reproduce some product we had in our program 20 years ago. And give the forum members a chance to buy a quality system for their restored 323i e21 models.

I have a question? What is a bespoke system? I'm also not sure what is a 6 branch middle box?
