Thanks. It wasn't stock when you added Borla? Wonder what gains would have been with a non restrictive pipe size...

Right - not stock vs stock+Borla

I'd still guess less than 10 HP, exhausts are rarely big HP gains without headers etc

Have any videos or clips of the sound? Thanks

I don't but coming from someone who's very fixated on noise, I was even a little disappointed at the quietness from touring

There's a subtle growl at start, slightly deeper rumble say under 40mph but I wouldn't have known it was aftermarket had I not bought it myself

If you want any noise at all, start at S type at the very least

has anyone purchased the GM Borla Cat-Back and Tips? I think the part numbers are 19329327 and 19303347.

Wait, I should have looked further. I wonder if we have the same part numbers as OP

 

[NowZoomer]

Part numbers vary due to 3 levers - brand, engine, wheelbase

You can see all the versions here
