Dude I am pimpn the **** out of this info! I wish I had it earlier. I would have not waisted my money on a GMPP Manifold. I have a flow goal of 425-450 CFM. I could have gotten away with the stock manifold and just replaced my dp and cat-back with a 2.5" system.
I guess the extra 25 CFM will be worth it in the long run. But for immidate gains I wish I would have started with the cat-back.

Hi ! Here are my flow calculation for some LSJ engine parts :
Stock Cat-back Exhaust (2,5" inlet to 2,25" outlet with stock muffler) : 300 CFM.
Now here are some replacement parts :
Stock catback with only the rear muffler replaced (the last portion is still in 2,25" tubing) : 350 CFM.
Hope this can help ...
Regards

The GMPP catbacks flow more than 300 cfm due to the fact people see an increase in power. Anyone have the info on the cfm to back up my proposterous claim?

I'd like to see the flow numbers on the intake manifold with the stock laminova port size, 15mm and 18mm.
