So, interestingly enough, I can't find the outer diameter of the piping on the Racing Beat Race Exhaust.

I'm inclined to think it has a 3" OD, considering the Rev8 uses 3" piping but why would they not post it in the description? This seems like something any enthusiast would like to know about a product, the OD of piping is what often sways users towards, or away from a purchase.

Perhaps its less than 3" for sound/weight reasons?

Can any owners chime in? I'd really like to run this exhaust as my next setup but would like to know the info before pulling the trigger. Thanks!

Here's a link to the description so you all know what I'm talking about ->

it's 3", it uses the same feed pipe as the cat-back muffler exhaust

 

Awesome, thanks Team! I wonder why they don't advertise the OD...
