   I came across a little website on tuning and they had a sort of guide on how to tune a standard TU exhaust manifold... (i know its easier to get a 4-2-1 ect ect but im short on cash and motivated to squeze a little more power out of it)
   
   anyway, ive got mine off, and theres a chunk of metal in it (see pic) which i want to remove, does anyone know the best way to get it out without making a mess of it?
   
   said pic...
   
   
   
   Cheers!

   WHY? thats there for a reason!. It seperates the exhaust gases which helps the flow upto the downpipe. Save your time and while its off look out for a second hand 4-2-1 manifold

   It wasnt suzukituning was it?
   Horseradish.
   
   Leave it in, itll make next to no difference, if anything itll make it worse.
   
   As above, save up and get a cheap 4 branch, theyre pennies second hand.

   Fair enough, ill take your words for it!
   
   What manifold will fit over a standard oil cooler on a 8v? a mk1 4-1 or a standard mk2 4-2-1??
   
   i dont want to buy one for it to not fit.

   as said leave it in place
   
   alot of cheap pattern down pipes have this part missing (have done since the ax and 205 gti days), i broke down miles from home and needed to get it fixed asap on my 309gti and all i could get was one with out the divider in it.
   
   the low down torque dropped right off, as that divider basicaly makes the exhaust in to a rather crude and not very well worked 4-2-1 system.

   Yeah i see what you mean! what about the ports or the whole ths for that matter, would it benefit from a quick polish?
