Iphone picked up a drone sound that is not representative, I think it is how I had the Iphone mounted it reverberated. There is no drone.

Thanks.
I originally did the 2.5" x-pipe and stock cats, it was way too quiet.
The 3" x-pipe and 100 cel cats transformed the car.

I'm glad you are enjoying it. The 3.0XP/100 HJS system is a truly great sounding package!
Here is an example of the type of system that Yell03 ended up with - SpeedTech 100 cell HJS catalysts w/ our 3.0 X-Pipe.

PM John, their prices are low compared to other systems.
You can go on their website for pricing, but definitely reach out to John.
