Dear all

what is the different between 5mm and 6mm pipes?

is it to say

5mm is designed to a low- mid speed race


and 6mm is designed to a high speed race?

You are refering to the size of the Stinger diameter (the pipe portion opened to atmosphere which expels the burned gases out).

It works as a pressure bleed valve and controls back-pressure, enhancing the port plugging efforts.

Stinger diameter affects the top and bottom end.
• Bigger = top end at the sacrifice of low end torque. More fuel consumption
• Smaller= low end at the sacrifice of high end revs. Less fuel consumption
Stinger length affects the top and bottom end.
• Shorter = top end at the sacrifice of low end torque.
• Longer = low end at the sacrifice of high end revs.

The stinger's ideal diameter and length are important to performance, but are limited and governed by most racing sanctioning bodies, therefore most comercially available pipes are designed to meet these regulations. basically the 5mm oulet is legal and the 6mm is an outlaw option.

Thanks...very professional


So i always street running, wanne more top end and revs,

which pipe do u suggest?

thanks!

afm

for your OS TZ Speed Spec II, the best pipe is the OS 1050

i can only find information of 1040

"Perfect for OS .12 engine XZ, TZ and OS speed .12 XZ, TZ engiens.

O.S T-1040 tuned silencer has a shiny silver color. Specifically designed to develop maximum performance at a relatively lower engine RPM range. Exhaust outlet is slanted to the left toward the inlet. This product includes one tuned pipe and one pressure fitting.
"
it designed for low rpm with high perfomance, not high rpm

afm

Not true, since OS TZ engines were famous for their enormous torque power and lack of high speed, their Speed tuning division brought out the T-1040 pipe and now the T-1050 pipe with these statement "Exhaust for more power in medium and high speed power curve"
and I suscribe that statement, T-1050 pipe gives good high speed.

Where did you find these statement? can u share me the link

i cannt find anything about the pipe in os website

Thanks

afm

That info came from the old OS SPEED site which had the same info in either option of language (Japanese and English).

Todays site only opens all info in japanese option and its different than old one, so you must trust me on what i got at that time from their site.

You can go and check for yourself http://www.osspeed.com/

Just take the guys word. I have a Spec II TZ with the 1040 pipe and it screams.

kakluote

Terrible sorry !

i dont know why, i search all link in osspeed.com, still can not find any info about 1050...............

make me Crazy............................................. ..

kakluote

Thanks for you info

what about the high rpm power with your pipe?

as i know 1040 is designed to performance good in low and mid rpm.


thanks!

kakluote

Just bought a 2nd 1050

looking forward to see the performance with my spec2

kakluote

just try 1050 with spec2


very cool performance



good bottom end and much better top end than hec 5mm
