GM Factory performance Exhaust

[crf450r]

I have a 2021 2500hd  6.6L Gas ordered

 

I believe I have read every "exhaust" post that I could find here,  also very helpful info from this  site I might add.  I know that borla makes the GM exhaust, and it is a "mild" tone,  I am not interested in anything loud,  I have a couple of questions:

 

1.  If anyone has installed the GM OEM performance exhaust,  do you have a video on the sound ?

2.  Is there any affect on performance, good or bad?  I don't need better performance on top end, and don't want to loose low end torque, Working on Motorcycles, different exhaust can move the power band around.

3.  Do  you think the OEM performance exhaust would be quieter than the Borla "Touring" option? Or the same?

 

Thank you

I get worse fuel economy because I like to hear the exhaust

Yes, the Borla exhaust from GM parts. There are times I wish it was not so loud but all in all I’m happy with it.

For the comparison here’s the stock exhaust on a 6.0
