We're putting the final touches on our resonated midpipe to complete our downpipe back exhaust. We've explictly tuned the midpipe with our MadDad Whisper series axleback although the midpipe can be bought standalone to work with others. Combined with a Whisper series axleback though you can get a power producing downpipe back(replaces the last two cats..the factory downpipes are still there) exhaust that has the volume level of most axleback only systems. Have your cake and eat it too.
