mu exhaust system
hi guys me again,removing rear muffler cause it so bloody big and keeps getting hooked up.Theres a gizmo half way along exhaust what is it and do i need it , someone said its an oxygen sensor is this right and to just remove it but unsure. So any help on this matter would be great
Re: mu exhaust system
Hi fatcat,
I have just done my exhaust on my truck to a 2.5 inch from the Turbo, I had an exhaust brake just after the flexy which is ok to remove, this is only needed in very cold conditions.
Is it a big square flange thing with a cable comming of it to and other unit
Cheers

Re: mu exhaust system
its not a exhaust brake the flap closes on cold mornings when you push the button on the dash, it allows the engine to heat up faster and run better while cold. i ditched my whole system for a strait thru 2.5 system and the dump pipe even has the waste gate plumbed in seperately
needs more curry

Cool thanks mud_slinger,
I dont know why I keep referring to it as an Exhaust brake, it kinda looks like one.
I have also done the same to mine what you did, what an improvment

Hey GotFlex,
I have not done the intercooler yet when do you need to add an intercooler?
I have not done anything with the fuel or boost, I have a boost of 14psi 2.5 from turbo and medium muffler.
Sorry for hyjacking this post
