Hi guys I just got my 2005 Z with an automatic transmission. I hate the auto but I couldn't beat the price for the condition it's in, won't be auto for long anyways.

Anyways coming from a straightpiped rx7 the stock exhaust is wayyy too quiet and I was looking at test pipes for now since they are cheap. I was looking at the Invidia and saw that there is two different size piping for the same years 2003-2007. There is 50mm and 60mm.

Does it matter which size I buy? Will only one size fit or can I pick either?

Sorry if this is a scrandy question, but I'm used to 30 year old technology and custom making stuff not ordering to fit.

 

Difference is 10MM....either should work.

 

In for the manual conversion swap

 

That's what I figured Conway but I wasn't completely sure if different trims came with different size exhausts, thanks.

And of course the manual swap is coming, my left leg is starting to get cramps

 

LOL, Bigger is always better! So go with 60MM.
