Most liked posts in thread: RMW STREET HEADER

Good luck Both in finding one, and in keeping it operational

you can have mine when you pry it from my cold, dead cabrio. I luv it.

But if it breaks again, I might decide to part with it....:lol:

it may well be the greatest, yet most breakage prone, MINI upgrade of all time.

Mine was rebuilt as the "final generation" with the better flex joint... we'll see how that holds up. Just put it back on a week ago and have driven it hard, and - so far - no codes.

 

Blimey why did you go with the street header and not the race one? I've have the race header for two years and no troubles yet.

 

1) Catalytic converters actually serve a purpose on street cars
2) In this state, it's non-trivial to pass annual inspection without one.

 

I think that's just an RMW 'feature'. Every part I had from them save their cylinder head needed 'rework'. So much for the quality and engineering up front, eh?

 

codes.... depends on what code you're getting... I never got the codes the other folks did - I only got a "system rich condition" which actually I think results from the first O2 sensor. I don't have the J bung - but one or both bungs were a bit different on the rebuilt unit I got.

Yep - several folks had the original style flex joints break. The new ones are significantly better - but no reports on long term durability just yet.

yes - mine was rebuilt with components of the last version he did (I think) - and yes, so far, these seem to be doing better. But its relatively early yet.

 

Old flex joint is the bare "accordion" type like in the pic you posted.
New flex joint has a woven sheath similar to the OEM header.

.... if you can find a new one... someone said he doesn't make it anymore? But I haven't verified that with jan...

 

Scooper,

Drop me a private message if you'd like... as I'm scheduled to have my third RMW street header installed later this week... and I'm still getting codes and broken exhaust components on the car.

It's quite tempting to 86 the header and go with a methanol kit instead.... plus it will help me return to my "sleeper status" I enjoy so much!

 

That header sure does transform the sound of the car into something magical. Can't say the same for some of the others out there.

 

The race header has a CAT. Ours has been trouble free as well :cornut:

 

ReallY???? Wow... thought it was catless.

But it IS longer - right? Doesn't work with standard MINI aftermarket exhausts?

If not then I'm totally confused...

 

So if ya'll are gonna discuss this here as opposed to someplace where it might get found how about I move the relevant parts?

 

it makes perfect sense here.

race header = longtube design with no cat which requires shortened midpipe and lengthened O2 sensor lead. The RMW midpipe had a cat in it since the header did not.

shorty header = stock length with cat that works with all catbacks (i.e. equivalent to stock header)

 

Ahhhhhhhhhhhhh

So me and b'trugger were kinda both right... :cornut:

 

Me too preferably new flex joint street header.

 

I have had no issues with any of my RMW parts...

 

The race header designation...

just means the primaries are the right length for the engine power band. The stock and street versions are constrained by packaging. Any header can have a cat added after it, it just may not be welded in like the stock unit. All the longer headers are not compatible with cat-backs designed for the factory exhaust manifold.
