Stainless Steel Exhausts

Hi,

I need to replace the exhaust on my 1998 Range Rover 4.6 HSE and I want to
fit a stainless steel system. I've looked at Rimmer Bros and RPI
engineering (amongst others) and all have highly polished bling boy-racer
style tailpipes. Does anyone know of a heat resistant black paint
(preferably spray) that will adhere to polished stainless steel? Does
anyone have experience of the stainless systems from either of these
suppliers? From their website pictures they look to be identical systems.
Does anyone have any experience of the quad pipe systems?

Thanks in advance

Ive got a rimmer exhaust on the 101. Its not polished - its only as
shiny as stainless steel is as standard.

I put a Rimmer system on ther 4.6 RR - although the tailpipes are shiny,
there's only a couple of inches showing, and that's below bumper level.
Hardly notice it. You will need to trim the bottom edge of the bumper
though. Highly recommended.

You can buy pre bent tubing in various diameters and materials if you
fancy building your own.
I know a bloke currently building a 3" exhaust for a saab. I'll try
and get the details of the place he's getting his bits from. He said
they have a web page with all the available bits on

I've not dealt with Rpi for exhausts, but they were very helpful with my
Weber 500.


My 3.5 V8 has a Rimmer stainless exhaust, the product was fine, delivery
very good, but I had some trouble with a warranty claim when the middle
silencer started rattling. I rang them to see what the returns procedure was
and they explained that they don't just swap the faulty part for new one,
they collect it, repair it and deliver it back, usually within a week. Since
I was taking the gearbox out a few months later I arranged to leave it until
then to save having the vehicle off the road unnecessarily.

So, a few months later when the vehicle was off the road, I rang Rimmers who
collected it as arranged and hoped it would be back at about the same time
as the gearbox came back from the rebuilders. Sure enough, a box from
Rimmers arrived, containing a brand new silencer! I assumed my old one had
been to bad to repair and they had replaced it.

A few weeks later I received a letter from a "manager" at Rimmers containing
what I can only describe as a thorough b*llocking. (Excuse the asterisk -
if substitute it with an "o" the tiscali news server refuses to forward it!)
He explained that it was not their policy to replace faulty parts, but to
repair
them, and I should never expect this treatment again!

I wrote back complaining about the tone of the letter and its implication
that I had somehow extorted a new silencer from them, but never got a reply!

I still have no idea why they sent me a new silencer without any
explanation, and even less why they seemed to think I was wrong to accept
it!

A steering brake that operates on the rear wheels, I've seen them used
on Hurst Hemi Under Glass, a dragster that spends most of its time with
the nose pointing skywards, the fiddle brakes allow steering when the
front wheels are off the ground :)

The under glass bit refers to a glass panel in the floor that gives the
driver a bit of forward vision. Totally crazy machine - I can put a
picture online if you want to see it in action.

Got to see that then.

also used on trials cars - the ability to brake rear wheels individually can
be used to emulate traction control manually. in other words, you brake the
wheel that's unloaded and therefore spinning, in the hope that the other one
has more grip.

You want to make the gas flow better. Bigger exhaust and also cut out
any restrictive bits such as harsh bends.

From what i've been learning about exhausts for saab turbo engines
(and if you are working with a tdi presumably some of this will
transfer?) - just changing the bit where the gas exits the turbo makes
a lot of difference.
In the case of the saab, you replace a fairly harsh 2" diameter cast
90 degree bend with a bit of 3 inch pipe that manages to turn the 90
degrees by doing it as multiple smaller angles (compare the pictures
here
http://www.saabcentral.com/forums/showpost.php?p=509881&postcount=2
for an example).
It however takes up more space and you have to shift stuff out of the
way to achieve it.

With a turbo engine, you dont gain a whole lot of noise by putting
bigger and less restrictive exhausts on as the turbo tends to 'muffle'
it all in a way (so i'm told). My car also has had the mid exhaust box
replaced by a straight through pipe. makes it slightly more throaty
when you get moving - but not in an obnoxious way!

I think you want to be building an exhaust that is as big as you can
manage, and that has nice gradual bends in place of any harsh ones :)

The guy driving it's equally crazy, IIRC he had just turned 65 when I
took the photo in 2003. Super chap though, he really enjoyed putting on
a show for the crowds at Goodwood and was around the car much of the
weekend so plenty of opportunity to chat. But then that's the beauty of
Goodwood, fantastic access to cars and drivers. They've had a fair
selection of Paris-Dakkar vehicles there over the years as well (sort of
makes this a bit more on topic ;-) ).

It makes sense! - but there seem to be a fair few people with saab
turbo's saying that just improving the exhaust makes a difference.

I don't think that the 'proper' gas-flowing (of both the manifolds and
the head) is quite so important when you have a turbo engine.
Something to do with the forced induction I think. It makes a
difference, but not as significantly as on an n/a engine.

(steve said he was building the exhaust for a 200tdi earlier)

I'm not an expert, but i've been playing with and researching turbo
engines recently. I've got a ported, polished and slightly improved
head ready to go on one when i get round to rebuilding it :) - so i
can put forward an educated opinion at a later date! (until then i
reserve the right to regurgitate things ive read and heard elsewhere!)

I reckon it still makes a difference. The gas flow is gonna be better,
whatever - many modern exhausts are restrictive in order to make 'em quiet,
though.

You're right, its the 200Tdi project I'm thinking of. I thought
polishing ports wasn't a good thing, for aerodynamic reasons, the rough
wall REDUCES friction rather than increases it ? Can you "port" a 200TDi
and make a worthwhile improvement I wonder.

I suspect this is more about turbulence - too clean a gas path on the inlet,
especially in a petrol engine, is supposed to lead to poor mixing. However,
in a diesel, that may be less relevant.

however, matching ports so there's no big step in the side would be helpful,
I think.

I slightly lied about the polishing bit. He's cleaned it up but still
left it with a rough finish, as he (the engine guy) said the same as
you - that this was better.
I trust the engine guy as he's been doing it for years!

That's right - a slight roughness to the surface produces turbulence which
(for reasons my O-level physics didn't cover) actually reduces friction.
It's the reason that golf balls have dimples.

Shaping ports to manifolds (inlet and exhaust) is worth doing, gives the gas
a fair chance of shooting though without banging its head on the step.
