Correct, but there are kits out there that come with 2.5" tubes.
I used 2.75", which was sufficient for stock block power at the time of development. However, it seems like customers are starting to push more and more power, with higher boost levels. I have built a couple of sets of 3" pipes in the past for those that intend on building their engines...but for the most part the 2.75" tubes will do the job.
The V-2.0 will come with 3" pipes, and that should be more than enough to push the stock block to it's absolute limits. Upgraded MAF sensors are available with the kit too, for those that build these engines and want to run 15+psi of boost safely.
