A check engine light…yes, that is what got me onto AmericanMuscle.com searching for new cats. That and an impending visit to our Vehicle Emissions Inspection station that I was deemed to fail. I plugged in our OBD-II scanner to find the code was for the catalytic converter on the passenger side. After I did a visual inspection, my S197 had no more left in those OEM converters. Hilariously, I demand more and more performance out of this daily driver as if it is a GT, not the V6 my money could only afford 7 years ago. This need for more prompted me to do some research already on the Pypes Mid-Muffler True Duals because I wanted the sound and power increase. As I looked at reviews trying to decide on cats,,mostly the reviews had recommended the Pypes High Flow Ceramic Catalytic Converter Kit along with the True Duals.
With a one click to purchase, I had no idea I was in for the ride of my life. I had these installed along with the pipes at a local shop and it took about four hours for the entire job for $300. In addition to the pipes sounding like archangels singing in heaven upon startup, when I left the shop and onto the main road, I felt like a 105mph pitch being caught by a baseball player – cupped into my leather seat tightly! The power was amazing as I throttled upwards in acceleration, causing me to forget the posted speed limit momentarily.
I’ve also noticed my CAI whistles a lot more upon acceleration and the RWHP has definitely increased. When I can get onto a Dyno I can call numbers, but knowing my old 'Stang and this new monster I’m creating…INCREASE!
As I mentioned on my AmericanMuscle.com review of the duals, I run my car at our local track and my best run on the last Test & Tune with my last set of upgrades (Screaming Demon Coils, Street Thunder sparkplug wires and NGX Iridium sparkplugs and a BBK CAI) was 15.519 secs/ Reaction Time 0.346 sec/ 1/4 mi @ 91.28mph. I'll post everything on my youtube site when I do go with the Pypes Cats and Duals. As a thumbnail, with all stock I ran a 15.759 sec/ Reaction Time 0.453 sec/ 1/4 mi @ 91.24mph.
It has been about a month now and I will say my gas mileage has improved, as well. I was doing about 15.89 mpg of mixed city and highway driving and now I’m at 19.24 mpg with the same type of driving.
