Can anyone tell me where the best place is to buy lagging to insulate my exhaust, how much and which part to do ( just downpipe or more)

 

agriemach.com,quaility stuff,can handle up 2 2000f,just done my up pipe and down pipe,u will need atleast 15ft by 2inch 4 ur d/pipe, reckon u can figure the rest out!regards.mark.

 

Why did you lag yours, did it mack any differance and did you take your exhaust off to do it.

 

Rally Designs. Powerap, part number RAP004. I've not applied it yet, so no firsthand experience yet. Value will depend on which section of the exhaust you're applying it to. The further back in the system, the less it will need lagging.

 

both aftermarket pipes,so where done when changed,u will need 2 take em off 2 do properly!

 

What advantages does fitting the lagging have ?

Is it there to stop too much heat escaping into the engine bay etc or is there something else less obvious ?

 

Scratch,

If I have this correct (and please don't quote me) I think it is to do with the fact that hot gas flows better than cold, also as gas cools it 'contracts' therefore where the uppipe is concerned the hotter the gas hitting the turbo, the better....as I said just my edukayted gess

 

Better flow due to hotter gases, less noise and heat emission from your exhaust. Cheap "modification" that worthwhile!
