Recently Finished Exhaust
 

I got my '15 GT back in February and finally got the exhaust how i want it. To start, I got the roush axle backs. These offered a good sound, but not much volume. They are made of the better quality T409 stainless steel and the chrome tips just look great. But it really wasn't a difficult install at all. Nor should it have been. Last week i got in my resonator delete h pipe from american muscle. This install was a bit more labor intensive due to having to pull out the entire catback. (technically just behind the cats). This made it for a much easier cut. Anywho, this really opened up the sound and volume! I get (positive) stares every time i drive it now. It is quiet while cruising at 70 mph and offers a good rumble at idle but opens up under load. And it rumbles so much. Almost like thunder. Very pleased with this setup!

TL;DR
Installed roush axle back and resonator delete h pipe. Best sound ever. Perfect volume.

I find your lack of video/sound clips disturbing.

Did you notice if the H pipe cross holes were full diameter and how were the welds?

The h pipe was Heartthrob brand. I didn't notice the cross holes but the welds looks good.
