Does anyone happen to know the size of the tubing between the axle back and mid pipe? I've tried searching and haven't been able to find anything.

Thanks!! How does your GT500 axle back sound with the resonator delete?

I measured my resonator ID inlet at 2.25". The other parts of the pipe are up to 2.75" ID but there are many areas flattened and the flow has a lot of pressure drops.

I decided to get the pypes catback, did some research on it and sounds pretty good!!
