EXHAUST mods, cats and heat shields
The basis of this query is EA82T, its big mutha cat straight after turbo, its heat shields or rather the fiddly bloody almost inaccessible M6 bolts with Brumby CONVERSION in mind.
Admired LTurbo's EA82T new 2.5" exhaust with a 'dog-like cat' beyond dump pipe and in line under drivers arse. Did not look at the time but assume there is just a standard dump pipe with no heat shields anymore . That would be excellent for my intended EA82T transplant _ I do not want to reuse heavy old cat, and being LPG only may just get away with no cat at all according to rumours.
These M6 bolts and heat shields are what really frustrates me in engine removals in my GLTM. I'd like to know that leaving them off is OK. I'd like to *%$# them right off for good, maybe use the Ford Falcon heat shield material on firewall instead.
For those who have modded your turbo engines exhaust or transplanted have you forgotten heat shields on cats, (or the cat altogether!) was there any heat shields on EJ turbos at all, did EJ turbo have a cat like EA82T in the dump pipe? Thinking not.
All these issuees wasting RAM space in head

Thinking I need to do mine for passing rego inspections or at least an engineers report. There must be some info on ruling just how much clearance there is NOT, before heat shields required.
Heat wrap has led to buil up of moisture around dump pipe on a WRXed Brumby I know of and pipe rusted out in no time. Those heat coatings applied inside and out gave better result - retaining that wnkfactor

I have an EA82T in a brumby, I bought it with no heat shields and was always doing boots.
These heat shields are not available anymore so made a small shield out of muffler wrap sandwiched between to angled pieces of gal. Bit crude but effective and bolts with 10ml bolt onto thread hole on down pipe. Had some exhaust work done at muffler place and they replaced the cat..no choice there really, they said it was stuffed so I went along with it.

You may be able to get a heat shield from an RX Turbos spare wheel brace and make something up to suit the MY/MA's bay .
MY RX has 3" tube off an admittedly non std Garrett turbo and its wrapped in Thermotec wrap as is my stainless tubular headers .
My down pipe has the cat just behind my RX's gearbox in 3" , you may be able to use 2.5 with a std turbo in a Brumby .
Cat in downpipe nasty bulky PITA , yes the EJ's do it like that too .

Yeah driving without a cat is just irresponsible.
Jono, this was my dump pipe. 2.5" mandrel bent tubing down to a 2.5" cat underneath the car, then 2.25" from there back.
