Stainless Steel Exhaust

[Trikes]

Been looking around on the Net for stainless extractors and system but only found one in the UK. Is there anyone making these parts in Oz?

As my engine is a 1.6 I'm wondering which style of Extractors - Cross Overs or 4-1. Engine currently has Cross Overs but there is a crack in the one of the Primary pipes.

Sud is used for Hill Climbs (when I get it going again) and because it runs Quaife C/R Dog Box and LSD it revs 4300 - 7100 on the track so I'm looking at the larger Primary Pipes - perhaps they are off a 33 (?). The rest of the System after the Extractors is 2 1/4".

I'm not a luver of heat in the engine bay hence my wanting a stainless system. All my cars have had stainless as I prefer not use Wrap.

Anyway any guidance here would be appreciated.

Don't know a lot about this subject, but the 33 extractors won't fit a Sud because the inboard discs get in the way.
The 1.5 33 has smaller pipes coming out the head, than does the 1.7, 2mm difference, if i remember rightly, but then where it goes to the joiner in the centre of the car, the 1.5 and 1.7 engines have the same exhaust going to tailpipe.
The leaded engines have the old style pipe in to pipe joiner in the centre of the car, the unleaded have a two bolt flange type as used on newer cars.
Some of those cross over extractor pipes run close to the engine and gearbox, and can heat the oil up a fair bit.
The cross over extractors fix up the problem on the Sud and 33 extractors, which are timed wrong.
Exhaust timing and pulse waves from the exhaust is a specialists field.
Tell us about the Quaife Dog Box, is it a 'H' pattern or motorbike sequencial type change, and does it work good, Colin.

My Sud has outboard Sprint Brakes and a Hydraulic Hand Brake with Bias Valve. Hard Pads for Targa and the latest spec 'soft' pads from Brakes Direct. I had no brakes in the Hill Climb at Baskerville last Month (scary).

The Quaife Dog Box is H Pattern and it's awesome.

Flat shifts no clutch on up shifts (just bang it thru), use clutch to come down. Combined with LSD I can 'cut' corners onto the grass etc and make up a lot of time. In Targa Tasmania 2016 we had 4 wheels on the grass shortening the course twice and what we were doing to Porsche's Wrx's Evo's and a Nissan GTr was embarrassing for them. Sure the Nissan ran away in a straight line but there are way more corners in Tassie.

Dog Box is 1000 times stronger than std box, that's how it is explained by Quaife.
