I just installed the Heartthrob H pipe on my 2016 GT. Just wanted to share my experience after driving it all day.
I had the mid pipe clamped and welded in because I didn't want to risk future exhaust leaks. Plus, I will not be getting rid of this car so I am modding it how I want it, not how the next owner might want it.
The car has a little more rumble. Sounds louder and deeper by a hair. At high RPMs the stock mufflers give a little metal tin sound. I will be getting Borla S Types later this summer so it should sound better.
I am VERY surprised by 1 thing after the install. I have drove about 150 miles today both City and Highway and my MPGs went from 17.1 to 17.7. I did not reset the mpg average or anything. I like having an all time average or the last 500 miles (whichever the cluster or computer stores).
I drove the car a lot trying to get past 17.1 while I had to stock resonator and even when babying it, I couldn't get it to go higher. So that was a nice surprise.
The car seems to accelerate a hair better also.
Here is a sound clip. Enjoy!
