90mm OD or ID?

[The Dan]

Circumference?

[SS8_Gohan]

no idea... by asking the question i'm guessing not all manufacturers use the same measurement? ie, some use OD and some ID?

but don't we always just refer to 3"/3.5"/4" exhausts? i'm assumed that was always the OD?

[pistol-pete]

if theyre the ones pictures then ive got a set (theyre ti too) and they are 80mm into a 90mm outlet

[Nee-san]

the J1349 test is for taxi's in California isn't it ?

Best way to figure out what you would need is calculate your required flow and run it against varying pipe diameters.

prob getting a little technical for me, but i can give it a crack. How would one go about doing this?

What's the price tag of those front pipes in Ti ?

[SS8_Gohan]

the Midori ones??? i think 126K yen retail for 90mm - approx $1600 before shipping

[Marko R1]

this front pipe looks to be the same configuration as my veilside full system.

i.e. my front pipes collect into a 90mm main pipe BUT mine is mandrel bent SS (not lobster back TI).

look like merge to 90mm, not twin 90mm

soooo sexy....

$1000 delivered (sunline )

[SiR_RB]

Nice...

I had some twin 76mm into 90mm front pipes made, huge and chunky not as nice as these to look at though hehe

And not to $$

[Piggaz]

Daniel, what about a set of Racepace front pipes? Twin 3 inch into a 4 inch merge, tuned length and a decent price too. The welds are just sex!!!!

[bigmikespec]

Pauly DIemar is actually making some front pipes these days, equal length and merge into 4", out of stainless... just under the four figure mark in price too!

I made a my tuned length front pipes out of mild steel, 3inch into 4inch merge.

The welds Arnt as pritty as the race pace ones, cause I use a mig. But once they all heat wrapped you don't see any welds or anything. Cost me around 150 bux in materials. And a day of my own time.

I'll post a pic tonite of them before being painted and wrapped. Can't do it now as I'm on my phone.

80mm Midori...90mm are same quality.

Took these pics at Midori

There for me :-)

There a twin 2.75" into a 4" merge, but the design could easily be modified into a twin 3" to 4" system.

[bigmikespec]

Yeah they looked good! Nice one mate.
