I just bought a 2008 Ram Hemi 5.7. I want to do a cold air intake and a new exhaust. Any info on brands and products that work?

 

i just put in my ebay cai. its sounds good at WOT and i noticed better mpg. it was only $50 with s&h.

 

K&N has been around awile so they've proven themselves pretty well for performance. And for exhaust you cant really go wrong with the top brands like magna flow,dynomax,flowmaster,corsa ect....It just depends on what sound you like and how loud you want it and the cool thing is that alot of those exhaust companys have sound clips on their website's or you can goon you tube and hear them.

 

I would suggest a Ram Hammer CAI and the Corsa sport cat back exhaust system!

 

I just installed a flowmaster 50 series with dual exits behind the rear wheels. I havent decided wich cai yet, butI'm leanning towards the Ramhammer.Very happy with it so far, nice deeeep rumble at idle and wot. As far as performance ??? who cares it sounds good.

 

I have the K&N series 77 and Flowmaster 50HD behind Pacesetter LT Headers.

I have heard that the Ram Hammer is awsome, but wasn't available until recently. I bought my CAI in Sept. of '04 when my truck was just a couple of months old. I should have gotten the K&N series 63, however, because the chrome tube may look nice, but it REALLY echoes the EGR valve noise when you give it throttle.
The Flowmaster sounds very good, especially with the headers, again, I got the muffler when my truck was almost new. Research I've done since has told me that Flowmaster mufflers are not that good for performance, often flowing worse than stock mufflers. The chambered design really sacrifices flow for that classic Flowmaster sound...

 

Looks like K&N 63 is the way to go but it is not CARB exempt. I live in California the truck is Cali smoged. Will that screw with the computer? Not street legal? Does that only effect the emissions testing?

 

Does the Ram Hammer or dual exhaust affect the lifetime powertrain warranty? I would hate to have dodge come back and try to void it....

 

Hey bones post a pic of your truck if you could i wanna see the Orange And i dont think it voids your warrenty they just wont work on that portion of the truck if something goes wrong.

 

I have the 63 series K&N and it's been on over a year and I love it.I live in Cal.and my smog guy said by the time I need a smog that it would be CARB legal.If not I'll just switch it back,it's easy.
