sounds alot like matrix then.but im no mechanic the two pipes will get warm due to thier postition at the back of the engine but the should be piping hot if its working.one is in and one is out you see.

as for fitting.i havent done it myself,but as far as i know its the bottom half (console)out of the way and a fiddly job to manouvre round the pedals.

someone may know a quicker way.but im going by saff experience when my mate did mine
