I've got an 04 Hemi Ram RC SLT and had a 50 series Flowmaster installed (single in/dual out) with dumps. Immediately I noticed a drop in performance with the seat of the pants meter. I'm thinking about getting the Warlock mufflers with the removeable plugs and running true duals with an "h" pipe and having the tailpipes exit before the rear tire. What do you guys think about this setup? Anybody had Warlock mufflers?

I have never heard of war lock exhaust. I personly like dynomax straight through design.I have notice more of a difference with them.

 

if you are going to run true duals, dont run an h pipe run an x pipe, i personally like my magnaflow i put on my hemi, sounds great and no power loss like many mufflers right now on this truck

 

do a hi-flow cat, and a single 3inch w/ a 40 series flowmaster.
the deep, non-krackling, sound that everyone likes.

 

Maybe you lost power because of your dump. Could be too little back pressure.

Agreed... I put in a 3"in 2 1/2" dual out 50 series & notice loss on the low end.

 

I have cut out everything up to the o2 senser behind the cats and put on dynomax 3" in /out bullet race mufflers one on each bank with 3" tailpipes coming in front of rear tires. one passanger side and one on driver side. And it is very loud but side great

 

I got a Dual Side Exit (Single in-Two out) made by SpinTech and I noticed a big difference when I had it installed. Thats with 3-inch pipes, eliminated a lot of bends from the stcok exhaust so maybe thats where most of my performance came from but either way I love it. It was between a Magnaflow and spintech for me, I went with Spintech because it had a much Louder and aggresive sound where as the Magnoflow allowed the Truck to Breath better over all but was wayy to soft in terms of sound..
