It will barely be noticeable. The gains from having a better intercooler far outweigh the volume increase. Most people don't even notice going from stock to say a 7.5'' race IC. The stock snails spin up VERY fast. They also produce a TON of heat. Hence the stock IC being useless.

As far as CX racing, get the 4'' thick version, not the 3.5'' everyone seems to buy if they still sell it. You have to call and ask it is not on the website. IIRC the 4'' is like $475? 3.5'' is $420 Getting very close to the cost the the BMS or VRSF 7.5'' race intercoolers.

The VRSF race is 3'' in and out vs. 2.5" Inlet & Outlet with the CX racing. Not a big deal unless you are shooting for big numbers. The big difference is weight. CXRacing is 18lbs vs VRSF 45 lbs. That is a HUGE difference in favor of VRSF.

I vote get the largest you wallet can afford.
