Thinking about getting an invidia test pipe for my 04 s2k. Don't know what the difference between the 60mm and 70mm one. Which one would be better. I'm not planning on doing a turbo or a SC or anything crazy like that. Just simply bolt ons and what not. Just before I pull the trigger and buy it, I wanna know which one would be better suited for my plans and needs. 04 S2K w/ invidia dual tipped exhaust, k&n fipk intake so far. Planning doing headers maybe later this year or early next. Please help!!

 

whichever you choose, be sure to grab a couple spark plug defoulers for your o2 sensor

 

Meaning, CEL fix?

 

Just cause it has a built-in "cel-fix" it may not work but can be resolved using the drilled defoulers. Also, make sure you match your exhaust diameter. Its almost always better to go from smaller to larger from header to tip.
