Thumbs up FLOWMASTER #17443 cat back installed

Well, got the flowmaster cat back system in from 21st century exhaust and took it yesterday to get the JBA off and this one put on. The flowmaster went on much more smoothly than did the JBA. All we had to do was cut 37.75 off the H pipes because I have a regular cab and everything else lined up perfectly.

If you remember, the JBA sounded ok at idle and ok on throttle but the cab drone while cruising between 1500-2000rpms was unbearable. Even my wife complained about it and she typically doesn't care about things like that.

When I started the truck after putting on the flowmaster, I could tell the tone was deeper. Even the muffler guy commented on the deep sound. When pulling out and going through the gears, the truck maintains that deep aggressive sound--unlike the JBA that gave up at certain rpm's. While cruising between 65-75 where the rpm's run between 1500-2000, the truck is much much quieter now. Hardly no drone to speak of. I couldn't be happier. Oh yea, my low end is back. The truck has immediate throttle response again and has no trouble squeeling the tires.

I'm going to do my best to get clips and post them before the weekend so you can hear it first hand.
