titanium exhaust

[MiniLandy]

Other suggestions:

• Drive without shoes on
• Poo before you drive it
• Remove small change out of the door pockets

Seriously though, how much is a Ti system likely to weigh? 30kg for your steel one is a lot, but how much could that be dropped by doing like Dan mentioned, and having a well thought through stainless one made up?

Is it worth asking Carl Austin at Force Racing for some advice ? He might even be able to fab one for you ?

I dread to think of the price when you look at the price of the lower rover metro arms that they sell £550 and that's with no rose joints and if you want them on car adjustable it's even more.

With all the ti/alloy/carbon parts now available for minis I'm surprised no one makes a lightweight exhaust. I might have found an affordable solution, will update when I have more info.

Good man!

Doesn't get much lighter than this:

It’s my cardboard tube idea isn’t it?!

not quite, but i have found a place that sells 2" plastic drainpipe tube - i'm sure it will take the heat as its only from the flexi back and it's very light

Great idea, much easier to get pre-made bends too!
I wouldn’t get the push fit type, I don’t think the o rings would cope, but the weld together type with the poly pipe cement would work and be less likely to blow at the joints.

All jokes aside
If you took a car with an original equipped Ti exhaust and replaced it with a stainless or mild steel jobby , it wouldn’t be any slower.
In our real world cars a whole lot of lightweight bits you will net a tiny gain in all areas. Consider replacing rotational parts with light weight bits like smaller or lightweight rims or a lightweight flywheel too

Agree, the only advantages are the weight and the “exotic” sound.

He already has a lightweight flywheel and 10” wheels and I doubt he’ll find 10’s that are lighter in a style that suit a sleeper.

There are lightweight suspension and braking parts that will make a big difference to handling as it’s unsprung weight, starts getting expensive though Gaz, trust me!

Yes Dan. I remember you saved a little weight by getting an aluminium plate on your wiper motor. That saved around 4 grams...

Looks pretty too

I'm not worried about saving loads of weight, i was only really looking into this as my exhaust system is heavier than most due to it having extra large boxes etc. I could fit a single (smaller) box system in thinner stainless and save a fair bit of weight, but i like the volume of my exhaust so really needs to be a twin with decent size boxes. I've been looking into using titanium motorbike exhaust as there's loads of them on ebay very cheap but the only problem is making them fit - i can't weld it like mild or stainless steel. and the other problem is i think they will be pretty noisy.

i made a rear exhaust out of copper pipe once, i didnt bother with the back box just had a middle box and stretched the copper pipe out gradualy getting wider towards the end, it was loud at low revs and not a t high revs, sounded very odd.
