2009/2010 Exhaust question
So I came across this article an article on Popular Mechanics online about the 2009 Ram and I started wondering something. Here's the link http://www.popularmechanics.com/cars/news/4279138
So they say...
"Dodge says variable valve timing, a higher 10.5:1 compression ratio, re-ported heads, less-restrictive breathing and an active intake system, account for the gains."
So if it comes with an active intake system and less restrictive breathing, does it really make that much difference to put a CAI?
"The active intake system feeds filtered air to long intake runners when low-end torque is needed and automatically switches to short runners as the revs climb. The Hemi exhales though a free flowing, slightly louder exhaust. The large 4-inch exhaust tips are frenched into the rear bumper for a cleaner look. And all Hemis are backed by a five speed automatic."
If the exhaust is already free flowing, then how much more free flowing is an after market exhaust?
I know that guys who do this stuff and dyno their trucks see differences but I was just curious.
Interesting article. Someone else also brought up a similar question regarding the possible advantages of upgrading to an aftermarket CAI.
I imagine with latest generations of RAMs the differences would be minimal compared to previous generations. That being said, I would also like to see before and after dyno runs with exhaust/cai's.
For me, mod'n my truck is a hobby, even though I may not see tremendous gains in hp/tq, customizing my truck is part of the fun.
I think exhaust wise, the only serious performance youd see would be with headers > true duals. Go from header collector > hi-flow-cat > 2.5" pipe > muffler > tip. Theres definitely no point in a catback on 09+ from what I see. Id like to see a true dual kit come out though for sure.
I just put the Volant CAI on mine and it sure seems like there is a difference. I was shocked at the sound when you apply a heavy foot. I am researching which exhaust to go with, and considering adding headers (not sure if adding headers later would be a problem).
