Tuner said 3" exhaust isn't necessary. It will just be louder and heavier.
I found this post helpful

3" exhaust is absolutely unnecessary unless you add a big turbo and plan to make more than 400whp..In other words, even with FI 2.5" should be more than enough for majority of the people..I would definitely ask for evidence (before and after dyno data) otherwise it's just another internet talk |

This has been debated for years and some people claim too large of an exhaust (for SC not for a turbo application of course) even hurts the low end torque.
Since the Rotrex kits in general makes a lot more power up top and lacks some low end power -as opposed to positive displacement SC s- I always thought it would be more beneficial to keep the low end TQ in expense to lose some top end (after 7200 rpm !!) and of course if it makes any difference

Looks like I will be going back to my original plan of a 2.5" setup:
JDL catless UEL (for more low end power and subie rumble)
JDL 2.5" overpipe
JDL 2.5" catted/resonated frontpipe
2.5" ARK DT-S exhaust or 2.5" JDL D2 exhaust
Now I just need to decide between the ARK and JDL catbacks.
