Car Forum / Land Rover Cars / August 2005Stainless 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 Alan C >Hi, > [quoted text clipped - 6 lines] >suppliers?

It's in a 101 with a 4.6L V8 from a Rangie, so you should be fine. Worth it if only for the sound alone, but don't worry about the looks, it'll soon fade in and look like a normal exhaust, 'cept without the rust :-) so Mother" <"@ {m} @ was, like... >> anyone have experience of the stainless systems from either of these >> suppliers?

Hardly notice it. You will need to trim the bottom edge of the bumper though. Highly recommended.

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 :) >You want to make the gas flow better. Bigger exhaust and also cut out >any restrictive bits such as harsh bends. Partly, and mostly, but not entirely. Improving the flow at the exhaust is good, but only if you have also gas-flowed the inlet and exhaust manifolds too (yes, ans perhaps looking at trimming on the heads themselves to get rid of any stepping where they meet the manifolds). The science (The little bloke at RPI does this quite well) is to ensure a good, clean flow throughout the entire process. Improving the flow at one point is ok, but will only provide marginal results compared to improving the flow throughout. Erm, if that makes sense :-) >>You want to make the gas flow better. Bigger exhaust and also cut out >>any restrictive bits such as harsh bends. [quoted text clipped - 9 lines] > >Erm, if that makes sense :-) 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 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. 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. Steve >You're right, its the 200Tdi project I'm thinking of.

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.

[quoted text clipped - 13 lines] >wall REDUCES friction rather than increases it ? Can you "port" a 200TDi > and make a worthwhile improvement I wonder. 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! so steve Taylor was, like... >You're right, its the 200Tdi project I'm thinking of.

Can you "port" > a 200TDi and make a worthwhile improvement I wonder. 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.

Any idea if 200Tdi's need this kind of treatment as a matter of course Rich ? Steve so Steve Taylor was, like... >> Shaping ports to manifolds (inlet and exhaust) is worth doing, gives >> the gas a fair chance of shooting though without banging its head on [quoted text clipped - 4 lines] > > Steve Not specifically, but any engine will benefit from what is effectively hand-finishing a product which is fairly crude from the factory. With the 2-stroke bike engines I used to work on, the effect can be dramatic. With a slow-revving lump like the Tdi, probably not as much, but it surely wouldn't do any harm. Whether it would be worth the effort, I can't say. SignatureRich ============================== Disco 300 Tdi auto S2a 88" SW Tiggrr (V8 trialler) >Partly, and mostly, but not entirely.

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.

Ouch Steve > Hi, > [quoted text clipped - 10 lines] > > Alan C 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! Andy Fox 110 V8 >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! Should mine ever need replacing and I get any grief I'll just go park Grumble up outside their stand at any of the shows and give them the simple choice of replacement or 12 foot banner along the side of the truck (and rev it - lots)... :-) Well, after a bit of searching and ringing around I went for the large bore twin pipe system from Rimmer Brothers. Considering a Land Rover main dealer wanted almost £700 for a mild steel exhaust I consider £569 for a stainless system with a lifetime guarantee money well spent. It's all a bit bright and bling for me (I like understated cars) so I'll be painting the rear silencer boxes black over the next couple of nights. Now just got to find time to fit it! Here's hoping the burble at tickover with this system is as nice as my TVR Griff 500 (yes, I know what I said about understated cars!).
