Rx7 from Hungary

[TOOL]

Forget Atkins George, their shipping costs are outrageous..... these are the ones you need and this company is very good...

Unless you go to the States for work in which case shipping from West coast to East coast is about $65 and you hope to get it through customs without being stung

still not much cheaper than the UK

Depends how much you spent.

Hi!

Thanks for the replies. The debate on the costs is obsolete now as I've ordered the bushings and also paid for them (no matter if I paid a lot, or a little)

What still puzzles me is the exhaust. Basically I see a few options:
- option 1: I take the car to a local exhaust guy here in Hungary who had never seen such a car in his entire life, and ask him to replace the whole exhaust system. He wouldn't understand the system, the third thin exhaust pipe, and will create something I'm really afraid of at a high cost (thinking if someone, who has such a fancy car would pay much more money for it).
- option 2: I make some condition monitoring to find out which part of the system is worn out/leaking. Then I order the parts (like catalityc converters, mufflers, manifolds etc.) through internet, replace the tubes and put it together. There are two problems with this solution: 1. if I take the car to a mechanic to search for the leaks and worn out parts (as I can't lift the car, I'll have to), he will disassemble the whole exhaust saying he can only find problems this way leading to option 1. 2. I don't have the equipment to do the job, so I'd have to go to a mechanic at the end going back to option 1.
- option 3: To order a full system through internet as Ian65 wrote:

As far as exhaust go, it's worth looking for a good second hand stainless system..... they are guaranteed for life as they don't rust so usually outlast the car. They are quite common on scrap RX7's in the Uk and usually sell for around £100 even if it cost another £100 to ship to Hungary, you would still be getting an exhaust at a decent price

However, I don't have sufficient information on this option, so I can't go this way (so this is leading again to option 1).

So, atm, I'm . Please . Thanks

99% of UK 1st generation cars have had the original exhaust completely removed and the air pump system taken off.

The original tends to go inside the front box where all the pipes go in and it's hard to repair it satisfactorily.
There's no catalytic coverer to worry about and in UK a standard type 'old car' single exhaust is acceptable so everyone dumps the old system

Except for two things it's easy enough to put another system on and all the information to do it is on this Forum.

The two things are:
You have to drop the coolant level and get the inlet manifold off (also note there's a hidden fixing underneath it). Why? because Mazda made it virtually impossible to get the thermal reactor 4th nut off if the inlet is in place. Keith (- Myatt) has a bent up spanner which can do it......if you haven't got one you'll struggle.

The second thing is you need the header pipe to bolt onto the engine exhaust and a gasket set.
Look through various threads on here for under bonnet pics and you'll see the headers in place.

From the header pipe back any exhaust specialist should be able to make a new system complete from stainless. In UK they can do it.....About £450.
So a second hand stainless system would be your best option all round. I think they're getting scarce now though??

Thank you for your answers.

Fortunately, my car is '84, so I don't have a thermal reactor.

Also, I'm still assessing the possible solutions, and I found this: http://www.rx7.com/store/rx7/saexhaust.html (Bönez Performance Converter System). What do you think about it?

Thanks!

Do us a photo of your exhaust sysyem as it comes off the engine George.

The info in the link doesn't work for UK 1984 12A'a so I think we'd like to see the thing you've got.

Please read post 238. If yours is a german rx7 you definitly have a thermo reactor no catalyt.
Your OEM exhaust parts: Red marked position will make problems especially 1984 because there is a small differenz to 1981 part.

Exactly as Thomas says, I do not believe you have a Cat. You should have the exhaust Thomas shows which has the Thermal Reactor. The red arrow is where I said the front silencer gives trouble. It breaks inside the pipes.

Hi,

I have no good pictures, but I'll try to shoot some. I think I have a problem at the same place you've marked with the red arrow, but I'll try to investigate.

However now I know and I'm pretty sure of it that my car has a thermal reactor, not a cat. I was confused before, because the '84 parts catalogue I found told that my car has a cat. Also I knew that I have a small third pipe near the rear muffler I was not sure where it was coming from. Now it's clear that it is part of the thermal reactor system or so. That's why I'm very interested about the differences between US and Europe specification Rx7s on I've found virtually no information so far.

Still, I'm unsure what to do next I guess that local exhaust specialists can't rebuild (and also wouldn't understand as they have never seen anything like this before ) a system with thermal reactor.
