I have (IMHO) the perfect balance of power/torque and sound across the entire RPM range,
a nice low rumble at idle that doesn't drone in the cab on the highway,
a Very healthy Hemi Growl at wide open throttle,
...no more resonators, finished off with the gorgeous 5" double walled polished stainless steel tips.

JBA Silver Ceramic Coated Shorty Headers.
Magnaflow Y pipe welded in with mandrel bent stainless steel elbows.
Magnaflow 16869 CatBack w/ 22" muffler (for 4G Hemi with bumper cut-out)

If I had to do it all over again I wouldnt change a thing :smiley_thumbs_up:

Keep in mind muffler shops lose money to those that DIY CatBack bolt-in systems.
They make their money on selling custom dual conversions

Right after I installed my CatBack I sold my new factory take-offs for $200.
A local Ram owner wanted to convert his si/so to si/do, and already swapped on a sport bumper.

Local exhaust shop quoted him over $450 (muffler, pipe,tips)
So he was pretty happy to cut his cost in half, and was okay with the stock sport muffler.

Win Win all around. He saved a ton,
My entire system with tips for a bit over $300 (net cost)

exhaust junkie has a dyno of the mufflex y pipe which includes the down pipes.

How quickly we forget ,

unless you have some new information,
that dyno chart isn't much good for anything unless you're out of toilet paper.

The Y on its own is nearly useless.


See this is the problem with people who say the stock exhaust is fine


The muffler is restrictive, the y pipe is restrictive, the exhaust manifolds are restrictive.

But!!! replacing all that still requires that you also make some intake air improvements as well.

an internal combustion engine is an air pump.
you simply cant force more air through until all intake/exhaust restrictions are opened up.

So you need a high flow air filter, a smooth transition tube from filter to the throttle body, preferably a secondary feeder tube to supply the airbox because the opening in the stock fender location is very constricted and finally a bored out throttle body.

Almost every place I looked a Magnaflow Y pipe was $27
and I cant imagine any shop charging more than hour labor to install one.

$150 tops! if they want more than that keep looking.
