does anyone know if these are any good?

OBX Exhaust Headers for 02-06 MINI Cooper ALL Header S on eBay Performance Tuning Parts, Car Tuning Styling, Cars, Parts Vehicles (item 230151914577, end time 22-Jul-07 21:06:55 BST)

I bought that manifold for my cooper last year! its a great manifold TBH the only thing is that its a decat manifold if you look at it....

I got it fitted and the fella who fitted it made a piece to fit the gap as he ddnt know i could get a decat pipe from else were. Although i dont know if something like the Janspeed decat pipe will fit.

I had to leave all that on my car so if anyone bought a 51 plate L/Y cooper with quicksilver exhaust and that header you got a bargain!

does it sound any better over standard?

[ScottyBoy]

At the moment i have a JCW exhaust and a janspeed manifold and the OBX manifold and quicksilver exhaust sounded alot better so yes it did lol.

[JCW_MC]

i have a JCW exhaust so i was hoping to add the obx to get better noise and hopefully abit better perfromance.

All depends on what your going to do about the big gap left were the decat pipe is gunna be, you will have to see if the GTT or Janspeed decat pipe will fit if they dont then you will have to have 1 specifically made and there is only 1 o2 sensor hole on the OBX header the MINI has 2 of these so thats another problem with this setup!

You should get some better performance from this as the standard manifold is pretty curvy etc the OBX header is alot better for the price!

I have just purchased a 4-2-1 manifold for my 210 works from mini mania this is supplied with a removable sports cat & de-cat pipe , both parts have O2 sensor holes for the nfittment of both sensors & you can purchase an O2 compansator for the post can sensor to prevent the dash light coming on.

What shap are the holes in the head mating section? round or the shape or the D shape they should be?

[MINI-Morgan]

They are the D shapes on the MM manifolds

If you have a ported cylinder head,you can open up the "D"into an oval to match the ported head ,you will lose a little low end torque but gain at the high end of the rev range ,unfortunately both are not possible ,unless you have 2 manifolds and swap them for the particular use of the car that day!!-unlikely!! - the difference is marginal anyway.
