New exhaust for 6.4 Hemi

[pistoncontracting]

Well folks, just curious if anyone has any experience with cat back systems for 6.4 hemi trucks? The interwebs is full of storys, both good and bad in relation to drone associated with the fuel saving mode of cutting cylinders.

So, before i spend the money, what say you? I don't want it too loud, but stock definitely sucks.

Thanks in advance

I didn't do a cat back system, but replaced the HUGE stock muffler with a Flowmaster 50 HD series. Has a nice increase in sound with very little drone. Worth the $250. There was a significant increase in throttle response and a few HP for sure.

I didn't do cat back but had a Flo-pro on my 5.7, farther back from the cab the less drone.

I put a Magnaflo catback on mine, part number 15333. Definitely increased the throttle response and has a good sound to it, makes people pay attention when your passing them. Paired it with a K&N filter and improved the litres per 100 as well.

I went with the cat forward exhaust on my 6.4 hemi. Included the 6.6 duramax. Little louder but huge gains!!!
