Hi all, ive been trying to find some information on these pipes. so far ive seen the pics in the "newbies look at this thread" I think it was called ,good info. what Id like to find out is: what kind of materials have been used e.g.stainless, mild steel ,alloy. Has anybody tried to insulate the pipe? who is making these things? What kind of success/improvment/prices have people had? I talked to a bullbar fabricator briefly this week about doing something in polished alloy and would like to find out as much as i can before meeting again. thanks Mat.
I had mine made up at an exhaust place. It looks good in the engine bay, but did nothing for performance. As for heat insulation, HPC coating would be a good solution, but is expensive. After a long drive, mine is only warm where is goes over the top of the extractors, so I reacon that some heat shielding on the exhaust manifold might be all you would need.

btw, mine is made from mild steel.
Thanks stockstanded & MustangNicko, these are the lines ive been thinking on. If you fit up improved cai then a 3" pipe for max flow it seems to me to be redundent if heat sink from the engine bay is going to heat the air before mixture. I dont know but the bay in the au seems extra hot to me. Im running headers without hpc. stockstanded how much did it cost you? you say it did nothing for performance now Im thinking I should look at this as a cosmetic mod. Does any one have any dyno results for a before & after on this mod? Im thinking it would probaly only increase performance inconjunction with a tunable chip.
I initially made these mods because my power curve hits a wall at 150rwkw and it was suggested to me that it was lack of intake flow. I am now pretty sure its my exhaust system thats buggered.
i got this same setup on my ef but it appears it runs abit hotter since i have added this, do use think its realated or a differnt problem??
the pipe is very hot when i try to touch it
