Question CAI Sound...

Hello Dodge Ram World... I've doing alot of reading on CAI systems and what is best, etc. But I have heard a few use the term "Better Sound" after installing one. Will this change the sound of the motor as well?

I am looking to have a FlowMaster Muffler installed sometime soon and was wondering if the combo of both would give the truck a very SWEET sound as well as a few more MPG's...

2007 Big Horn Quad Cab, 4.7 flex fuel, 4x4...

thanks all...

I have the Brute Force intake on my 07 and I can definitely tell the difference in sound. It's a great intake, I really like it. Yes, adding a Flowmaster muffler will give you a better sound, but adding a programmer (DiabloSport, Superchips, etc.) in addition to the intake & muffler will maximize your MPG potential

The intake will give the motor a deeper, throatier, more aggressive sound, and with an exhaust installed, the sound only gets better. I just started running an Airaid Modular Intake tube with a the stock air box & a K&N drop in filter. The intake is a little throatier than stock up to around 2500-2800, but when you push over 3000 it starts sounding reel good and open. From what I gather, when you add a cone filter into the mix, then the reel deep intake/motor sound is there.

As far as saving fuel....accelerate & decelerate slowly & smoothly. Don't go over 2200 rpm while accelerating. Drive at the speed limit, and use cruise control when you can. Keep your tires inflated from 35-38 psi. (you might not be saving on gas though, if you like to hear and feel your trucks performance... that's my problem ...... The 2008 4.7L sounds really good when it's breathing & exhausting like it should be!).

With my current intake set up & SI/DO XLerator dual exhaust, tires at 38 psi, I can get about 15 mpg city, 22 Hwy, which averages about 18.5 mpg each tank of gas.

airraid on mine changed my exhaust tone a little a little deeper of a rumble and yes under the hood sound changed for me to quite a bit louder but nothing to excessive or negative
