In developing the best exhaust kit on the
market for the JK,
Cool Tech performed a significant amount of research and
development. First, it was obvious that the best location for
a
muffler, if possible, would be under the mid-section of the JK and NOT
under the rear tub as virtually every other cat-back manufacturer
provides for. A change in the location of the muffler clearly improves
off-road clearance. Also, the stock muffler is large and very
restrictive. Cool Tech tested numerous different muffler
brands
and even several in/out muffler offset configurations within the same
muffler type. The objective was to find a muffler that added
a
nice exhaust tone but which was not loud and not "import" sounding.
Cool Tech could not accept a muffler design/configuration that would
allow an exhaust "drone" at any speed or RPM.
Finally, in relocating the muffler, a design had to be chosen that
would not transmit un-wanted heat to the floorboard of the
JK.
Once a location was chosen, only mufflers with internal heat shielding
were evaluated and tested. The final muffler choice ran substantially
cooler than other similar mufflers, and in Cool Tech's on-road testing,
the floorboard never became hot.
However, Cool Tech
wanted
to achieve an OEM-like installation, and chose to include a custom heat
shield in the final kit. The heat shield is extremely
effective. Regardless of the severe testing conditions, you
can
always place you hand on the floorboard from UNDERNEATH the JK and, at
most, it would be warm but NEVER hot.
Through exhaustive testing (lol), Cool Tech is proud to introduce the
best JK exhaust system on the market!!
The Cool Tech kit eliminates the stock muffler (29 lbs) and uses a
double heat shielded, fully polished stainless steel muffler
and
locates it in the mid-section of the JK. The Cool Tech design
retains the factory over-the-axle section. The factory piece is a
mandrel bent, full 2.5" piece that has been specially treated to resist
corrosion. By retaining this factory section, Cool Tech can
reduce costs and can also insure the full factory suspension (axle)
travel.
Do you want to compare this to a "typical"
relocation by a Muffler Shop?
Most muffler shops
will have MIG welders with steel (not stainless steel) wire. The Cool
Tech kit keeps your entire exhaust stainless steel - no welds to rust.
What muffler will
the shop use? Is it all-stainless? Does it have a
lifetime warranty? How will it sound? We tested many different mufflers!
Does the muffler
shop stock and install custom heat shields?
Does the muffler
shop use solid stainless steel exhaust hangers - and TIG weld them with
stainless rod? We do.
The
Cool Tech kit is
COMPLETE kit and comprised only of top-quality components including
these....
Unique Features:
Improved Exhaust Note
- the sound is a little bit louder and
deeper. It is NOT loud, nor will it drone at any constant
RPM. The exhaust note is deeper and does NOT sound like an
import
car.
Increased HP
- The muffler manufacturer has seen improvements
of 6-8 HP and with other mods, even more improvements can be seen.
Improved Muffler Location
- The muffler is moved to a "safer" off-roading
location with protection by the JK frame rails.
Weight Savings
- The Cool Tech exhaust system saves 14 lbs of
weight and better locates the weight between the axles.
Internally
illuminated
Connectors - great for
making connections at night!
