Hi Theo,

is it better to move this thread to project corner what you mean?

saluti Enzo

Hi Guys,

to avoid misunderstandings

please don't forget it's not mine!
it's a Guy in Austria who did this job.
i post only the progress here!!!

some exhaust modified work!

Can you explain to a non mechanic what the wrapping on the exhaust pipes is Enzo...I've seen that before somewhere.

Also the bolts..? 

Thanks......

"There are 3 main reasons for header wrap"

1. Looks nice

2. Less radiant heat, cuts down on heat exposure to bodywork, this helps greatly to reduce underhood temps.

3. Performance....
Header wrap retains the exhaust gas heat IN the pipe, reducing the passing by air from dropping the temp until it exits the pipe. The reason for this is increased exhaust gas velocity.....heat moves towards cold due to it's higher pressure....example, in your bathroom, turn on a space heater and run the shower full hot, leave the room and close the door, come back in five minutes and open the door, you'll get blasted in the face with the heat build up as soon as you open the door.....
The reason for wanting this effect in your engine is INTAKE SCAVENGING. For a few degrees of crankshaft rotation at the end of the exhaust stroke and beginning of the intake stroke, both the intake and exhaust valve are slightly open, this is called valve overlap. Overlap uses the speed of the exhaust gas as a "vacuum" to help draw a fresh intake charge into the cylinder, the faster the exhaust gas speed, the more vacuum you have to stronger draw more of an intake charge into the cylinder. This results in an increase in both horsepower and torque.

And if it is applied to the pipe PROPERLY, it looks great!!!  




"Also the bolts..?"
i think flue gas connection is the word take some measurements about the exhaust temperature or emissions analysis of exhaust gases per cylinder!

And PROPERLY, also this looks great!!!
