Origional Front pipe heat shielding .

[Pops]

G'day all , I was under my R33 checking out the exhaust to see exactly what I had under there and noticed that the dump and front pipe had some heat shieldind which looked like 2 piece mild/galvanised steel filled with a fibre galss packing .

Does anyone know if this is the original heat shielding which came from the factory ?

My cat back exhaust starts at 3" and increases to 3.5" after the first muffler . The dump and front pipe seem to be around 2.5" same as my cat . I'm just trying to see what I've got so I can finish off my exhaust e.g putting in a 3" front/dump pipe and 3"cat .

I've seen better metal finish on cans of baked beans...

just put a 3" front pipe and get rid of that factory front pipe and that ugly looking heat shielding tin.

Thats what I was asking , wether or not it was original . I am getting a front/dump pipe as soon as possible .

[rs73]

if it looks like this, yes then it's original...

looks ugly isn't it?

Pops, I would HIGHLY recommend you get the front and dump either heat wrapped, ceramic coated or HPCed - as without the stock pipe and heat sheilding you will notice a large in crease in engine bay temps. Plus as an added bonus, coating/wrapping can only increase cylinder scavanging (if it does, not too sure - but it wont hurt).

The reason I recommend this first is its an absolute PITA to try and do it on the car (heat wrap), or remove from the car to get it done. I did it the hard way:(

Some food for thought

Yes rs73 ugly isnt it , it has to go . Steve , I'll probably go with the heat wrap , just looking into a combined front/dump pipe and 3" cat , probably best to do them at the same time .

Pops,

If you want the best deal on thermal coatings in Sydney - talk to Col Ivory @ Ivory Special Coatings in Smithfield. Did a set of extractors for me at 1/2 the price of HPC. Also does exhaust housings, manifolds, whatever & real quick turnaround too.

Hope this adds, etc.

Yep, you're right Steve,

The hotter a gas is, the faster it travels- if you can retain heat within the pipe...so much the better + your cat converter will be more efficient ( only works above a certain temp).

Thanks BigDatto I'll check it out .

I pulled that heat shielding off

Can hear the turbo spool more

Why would u do that JimiH?

U r prolly gonna make ur car slower now.

Anyone know where I can have my front/dump pipe coated in Victoria?

I've heard that if incorrectly heat wrapped an exhaust may crack - I'm now scared of doing this myself!
