High Flow Cats For 5.7 Hemi
Dodge ram hemi stainless works headers & mid pipes are available with high flow cats & with factory or performance connections!Gain big power and great sound with a set of sw long tubes and mids.Go with a straight thru design instead of the flowmaster.Hhp 5.7l hemi awd high flow catalytic converter direct replacement system.
High flow catalytic converters are used for better exhaust flow.I could have bought a spare pcm and had it tuned via hemifever/diablo as i still have my tuner from my last challenger.I have seen shorty and longtubes make a good amount of power (when properly tuned for them), more so then just swapping out cats to hf or catless pipes.I was wondering if they’re emissions legal and what type of performance i should expect, if any.
I wish chrysler put more effort into adding horsepower to the v6 instead of focusing more on the 4.7 v8 and 5.7 hemi (and also making you buy the v8 to get qt2 and qd2).I would try to find the spot of the leak, anything near the o2’s can cause a false check engine light concearing the cats.If you have a front o2 prob it will act under powered and the computer will act goofy, the rears just say if the cats are working or not.If your cat needs replacement, install one that will get you through the smog check.
If your looking for louder i would first look into a muffler swap.It will vary depending on which ones we talk about.Magnaflow 51654 oem grade federal compliant universal catalytic converter.Magnaflow 94139 standard grade federal compliant universal catalytic converter.
Magnaflow high flow catalytic converter:Magnaflow® universal fit catalytic converter.No dyno’s have been done on the charger but many have been done on the r/t 5.7 challengers with significant gains.No they are not required , mine is a 2015 and all15 and up cars have a locked pcm.
Ok, back to the test.On a 5.7 i think the exhaust manifold is probably the best exhaust upgrade.Performance modifications to the exhaust system always focus on increasing flow capability to allow the engine to breathe more easily so that it can make more power.Proud to be the march 2013 member of the month!
Sent from my iphone using tapatalkStay with the stock cat, and it will not matter if you get a shorty or longtube.the stock cats will restrict anygains.The biggest gains you will see out of an r/t exhaust system are with longtubes and a cat delete.The high flow units still.
The more quickly the catalytic converter can do its job, the higher its flow capability is.The throttle response is greatly improved with the solo charger r/t cats.The throttle response is greatly improved with the solo r/t cats, and every one of our customers have commented on feeling the difference in hp (horse power) and torque.There is a difference between high flows and no cats.
These high flow catalytic converters are designed to fit all 2008 to 2014 6.10l and 6.40l dodge challenger hemi models.They are canamax high flow cats.They’re on the hhp site:With the addition of the solo high flow cats, your current exhaust note increases in volume by approximately 20% and the note deepens, richens, and becomes more full and rounded.
