Borla stingers to ataks but which size atak.....

[04ScSaleen325]

I was on summit racing today about to order the atak system when i realized there were 2 diff part numbers

One part number went from 2.250 intermediate pipe to 2.5 inch tailpipe size and then a 4inch tip

The second was a 2.5 inch intermediate pipe to 2.5 inch tailpipe to 3inch tip

My setup is kooks lt header 1 7/8 kooks off raod x. Which one should i get. Id like the 4 inch tips but it comes with the smaller pipes. My power level is 650rwhp.

Any ideas?

One is for a GT (140458) and the other is for a Cobra. You're looking for 140446.
