Tors with other headers. Performance and sound ?

[Ishrub]

Yes....Riding around with a Sheep in a sidecar will have that positive effect!

You need to read more thoroughly - "Great Uncle 'Kiwi' Jack & Molly Merino". I have a yellow labrador in mine!

At this stage, 1 5/8" O.D. one size up from the stock header size.

What's the ideal size, assuming there is one? How did you decide on the header design? Is your coated system hotter than the stock one? If so have you thought about adding heat shields? By the way, beautiful work.

 

[Pres10]

What size?

Maybe 2"

 

[Ishrub]

Maybe 2"

To clarify do you mean inner or outer pipe diameter of headers, collectors or mufflers?

 

[Pres10]

2" primary pipes. Similar to Carpentets.

Dougl, the stock header is 1½" O.D. when I first started this project I thought to build in 1¾" O.D. but decided to go with the 1 5/8" O.D.
The "design" was decided on as an improvement on the stock header, hence stepping up the one size.
The "style" is what I thought looked good, many have said this to be right.
My system being internally coated with a heat barrier ceramic coating and built tight into the head, set up with the correct tune actually runs a lot cooler than the stock system, reports back say no problem with heat at all.
Yes, have thought about heat shields, but as above, and also . . . haven't gotten there yet. Lots on at present.

PRES10 2" is great, and is required for high HP Engines, but not required for standard Engines.

ISHRUB; we are talking header pipe O.D. here, tail pipes are larger diameter again.

Hi Paul, I'm not a fan of the external silver coatings. They seam to dull over a short period of time. Is it possible to have them triple chromed and heat coated internally ?

Paul, I agree with Idaho about silver coatings. I might have missed your answer so I'll ask again, is it possible to have the pipes triple chromed and heat coated internally?

Beautiful looking pipes BTW.

Thanks Gregger.
Yes the headers can be chrome plated. then the internal heat barrier coating is applied.
It would add about NZ$300.00 to the cost, I asked about this recently. The headers, after plating, need to be totally masked externally prior to the internal coating process or else the chrome will be damaged.

And just FYI, "Triple Chrome Plating" is nothing flash at all, this is simply "salesman" speak when some one is trying to sell something "WOW, this is "Triple" chrome plated"
The truth is, standard chrome plating (show) has firstly a copper coating, then Nickle, then chrome, hence the term "Triple" chrome plate.
Hard chrome, is basically the same thing, but does not have the copper plate as copper is soft.
Also Hard chrome is plated to a certain (as required) thickness, then the item is precision ground to a specific size, fork stauncheons for example.

Good info Paul. Thanks for checking that out.

You wouldn't believe how many times I've heard that before

My wife is scared to go and visit her Mother in Los Angeles because each time she goes my bikes reproduce
