Alright, I'll measure under my car. But on the other hand, I've been trying to see how some OEM's do it. I found the underside of an LX Charger and it has a muffler in the center followed by two resonators by the tips; however, like mentioned, there is plenty of exhaust length (> 55"-70") between the muffler and tailpipes.

I also found some dual outlet Borla intercooled tips on Amazon prime that I really liked and are marked down like 65% compared to Borla's website. Or I can get standard round ones for $20 cheaper per tip. I might pull the trigger on those more for looks over trying to help the drone.
