After a few days with the Corsa, I have to say, it is perfect.
I had a Borla Touring on my 22 LTD High Country 6.2 and it had a deeper tone sometimes when in L9 at around 1000 rpm( 50mph) , I never cared for the tone. Above 2000 rpm and it had a deep roar that sounds good.
The corsa has more of a bark though.
It's a little louder.
Especially the cold starts. Sounds badass.
But it tames down.
Sound similar to a C7 Vette all the way through the rpms.
At cruise you can barely hear it in cab.
IMO after having both,
Corsa #1
Borla #2
