Hey.. i have a quick question about welding..

i want to weld my header to my exaust test pipe... and i like to ask if i need a flex
(?) pipe.. or not..

cause i've been told if i dont weld flex pipe in between the header and test pipe..
the header is gonna rip out when i push the motor...

so.. do I need flex pipe?

thanks for looking..

 

help...

 

anyone?

 

wha, you have no doughnut gasket?

 

If that is the case then yes you will need a flex.

 

yep you will need a flex pipe,or springs or your headers will most likely crack since they will take all the stress of the motor.
