Ke70 4Age Exhaust

[nz_83_dx]

Hi,

 

I am currently putting a 4age blue top into my ke70, went to a couple exhaust places and they're all recommending different sizes.

 

Would a 2, 2.3 or 2.5 inch system be best?

 

Thanks for the help

i went with 2.25 press bent with mine. its much of a much ness i think.

 

its only a stock 1.6L so i think 2.5 is a bit over the top.

ok sweet thanks for that.

 

So 2 inch should be fine then? what did the ae86's come standard with?

2.25" mandrel or press-bent would be ideal for an aftermarket system - it's only a 1.6L but likes to rev high so you need to take that into account.
