Well, I found a crack in my right(passenger side) exhaust manifold. Think I found the source of my Check Engine light. Anyone know of whom might manufacture a better exhaust manifold than the OEM units?? Think I'm gonna spring for the N.R.P. exhaust system as well. Any help in this area would be GREATLY APPRECIATED!!:D Anyone put the NRP exhaust system on their D1?? How loud is it?? Much louder than stock?? I've been the route of loud exhaust back when I was 18 on my '78 Blazers.....that wore thin real quick. So....the specifics....'97 Disco 1 SE7 4.0L. Thanks for the help guys!! | ||

What are you running for exhaust manifolds?? Stock OEM's?? Know of anywhere to pick up a better exhuast manifold setup?? Good thing I have my Ford Van!!LOL Drive the Ford til it breaks, then drive the Disco.....Hopefully, they'll stay in sync and NOT break down together!! THAT WOULD BE BAD!!:D | ||

stock. the stock exhaust header seems to work well and the NRP is set for the stockers. everyone seems to complain about the horsepower, it seems to me that for what its designed to do the horsepower is right on. mike w | ||

For what it's worth, the flanges at the bottom end of both manifolds on my '95 were cracked. I had them welded, and that was all it took. | ||

I put the NRP on my 97 and it was too loud for me. I called them and they sent me a second smaller muffler to replace the attenuator. I took it into a local shop and had it welded on. Sounds great. | ||

I wish the crack was on the flange. It's between the cylinders on the main exhaust passage. My course of action would be to take it off, drill at the ends of the cracks to stop the crack from spreading, and then weld it back up....HOWEVER, the manifold being cast metal has me worried that it could be repeated again. Was really hoping someone knew of an aftermarket header that could be put on. Hmmmmm, wonder if duct tape and tinfoil would fix it?? | ||

Hardly sounds worth repairing. I understand those cracks are very common. I'd be looking for an aftermarket piece. | ||

Replace both with some headers if you can't get a s/h unit. | ||
| Jeff Farrell (Jeff_farrell) New Member Username: Jeff_farrell Post Number: 6 Registered: 06-2003 |
I'd like to replace them w/ an aftermarket header/exhaust manifold. Just need to find someone who makes them. Ideas?? Anyone?? Bueller?? Bueller?? Anyone?? | ||

I have been looking for an aftermarket header as well, I have check with most of the major suppliers in the USA, and no one knows of a header for the Disco. There is a couple of companies that make them overseas, but they are for right hand drive only. (my guess is they do not have O2 sensors, but what do I know) I know that I contacted one manufacture overseas and got the following response. "Sorry we cant do headers for left hand drive. Thanks Wayne Brown ----- Original Message ----- From: Joey Shreve To: [email protected] Sent: Friday, June 13, 2003 1:10 AM Subject: Land Rover Header Question, first off I am in the USA so my '97 Disco 4.0 petrol has a catalytic converter. Do you make an header for my application? If yes, how much would it cost in USA dollars and shipping, or would you consider this? Thanks in advance, Joey Shreve Spencer, West Virginia USA" I also got this from suppliers here in the USA: Do you know of anyone who makes an aftermarket header (i.e. Performance) for a Disco I 4.0? I found a company in Oz but they do not make them for left hand drives. Sorry, with US exhaust laws we ave not gotten involved with headers. They hang down too far for our off road uses. Check with this company in the UK. http://www.rpiV8.com Thanks, ECR And this: Joey, We do not know of any headers for the '97 Discovery with Left hand drive at this time, Thanks for the inquiry, Bob -----Original Message----- From: Atlantic British [mailto:[email protected]] | ||

Get the Janspeed headers from Scorpion Racing in the UK. AdrianS has them on his 91 RR (3.9)... he posted pics a while back.... I'm sure you can get them for the Disco. BTW, improved performance... a lot | ||

Just sent an email to a couple of their Distributors. http://www.scorpion-racing.co.uk/ I beleive someone gave me this link awhile back in another thread, but could never find the headers on the site. Looked again today and found Janspeed, but the pictures would not come through. | ||

Could my exhaust manifold be cracked as well?? Sounds like and exhaust leak where the headers (?) are on the RH side of the engine. Don't know much about engines... If it is the manifold can I replace it myself (I am mechanically inclined)? Thanks in advance | ||

You can buy them here in OZ I think they are made by PACE Maker. | ||
| Shaun Power (Shaunp) Member Username: Shaunp Post Number: 52 Registered: 05-2003 |
Try this link they sell PACE MAKER and HM HEADERs http://www.onautos.com.au | ||

Thanks for all the links guys!! I've fired off a few emails to DOWN UNDER. A few of those from the Scorpion Racing site and I just sent one to Onautos.com.au. Guess I'll be hearing back from them tomorrow some time. I'll keep you posted as to prices and availablity. There just has to be a better system out there than the OEM units. Too bad RPI doens't make a stainless set of headers!!  | ||

Ok, just got these emails back from the land of Oz. Things aren't looking promising........ This was the exchange from OnAutos.com.au Jeff, Thanks for your enquiry. Dont they make the headers in the US? Trevor H Online Performance Autos No Trevor, They don't seem to make headers in the US for an OBSCURE ENGLISH ENGINE. Hence, my seeking a header from a couple of thousand miles away. So......back to the question at hand.......yeah or nay?? you guys have any headers for the 4.0L V8 Rover engine LH drive?? Thanks Jeff I am trying to find out if they will fit as we speak and will let you know shortly. Trevor H Online Performance Autos Ok...... Sorry about the terse reply. Didn't realize you were looking them up. Believe me, I've been doing some searching to see if these are fact or myth. Disco is down w/ cracked RH exhaust manifold. Not really anxious to pull it off and weld it back up again, nor replace it w/ another piece of cast. Thanx for the effort Trev!! It must be a commen problem as I have meing selling a lot of these lately. Trevor H Online Performance Autos Jeff, I cant get a confirmation either way but I would be leaning towards no as they are a very tight fit as it is. I am sorry but that is as much info as I can get.

Jeff East caost bull bars export stuff and they sell Long ranger tanks. I think you can get 2 X 50l aux tanks and 136L replacement tank www.ecb.com.au | ||

"OBSCURE ENGLISH ENGINE" - lol, it's a small block buick. Buick headers will fit the engine, the question is clearence in the D1 bay/frame area. D90's fit the buick headers with little problem. Of course you'd have to weld in your own 02 sensor bungs. Bill | ||
| Joey (Joey4420) Member Username: Joey4420 Post Number: 80 Registered: 04-2003 |
If it is that easy, I will ask the silly question. Where do I buy small block buick headers? And is there a certian size or model that works better? | ||
| Jeff Farrell (Jeff_farrell) New Member Username: Jeff_farrell Post Number: 9 Registered: 06-2003 |
AAAaaaaaahhhhh, your kidding me!! The 4.0L is a small block Buick engine??(blush!!) Ok, so that makes things mmmmuuuuuucccccchhh simpler in locating parts!! Thanks for that little Nuggett of wisdom Bill. And as for making them fit....well, Bigger Hammer, Bigger Wrench, and a little more Heat AND THERE'S NOTHING THAT I CAN'T BREAK!!:D Welding the O2 sensor on is minor. I talked to a local shop today about having a set of headers built (That's all they do is build headers.). They were talking in the range of $1200-$1500!!!!OOOOwwwwww, my aching wallet!! Shaun, thanks for the info on the Long Ranger tanks......have to run out to the truck for the HP 48 calculator for the conversion to US gallons!! And Joey does bring a valid point...Bill, do you know what headers would work best or which small block Buick LR used??(assuming more than one engine is out there....haven't done research in that direction yet.) And as for the other people I've contacted for headers.... HM headers.....they don't make headers for LH drive Disco's. They have some for the RH drives though. DT Performance.....same result. "It's only easy if you know how to do it." |
