Spectre
 
I recently installed a Spectre CAI. Disconnected the battery so the computer would figure out that somethings changed. I haven't put many miles on it ( less then 35). But I noticed that at about 35mphish I can hear a what I think is a possible backfire then all is normal. I don't know if it is the computer not yet figuring out that something has changed or if I have an issue. I didn't notice it with the stock filter and all. Any thoughts would be appreciated. Thanks in advance!

is it more of a girgling sound, then when you give it a little more gas, it goes away and the tone gets deeper?

If it is, I get that on my 07 QC Hemi right after I put the K&N CAI in. I think its because I removed the big Hemi hat "Baffle" so the sound is more noticeable.

I also heard that it may be the EGR valve but not too sure about that...

It's more of a PPFFTT noise if you can imagine that...lol . Lie an old backfire from the carb noise( If it had a crab lol.)

I had that on my '06 with the 4.7; it was normal according to my dealer. Just couldn't hear the noise with all the baffles that were removed.

That's normal. Just make sure that all your connections are tight.
