OE vs Hoffmann Exhaust

[driversdomainuk 8]

Hi

 

has anyone tested the performance differences between an original 1.9 GTI exhaust with the 4-2-1 arrangement vs a non OE / Hoffmann or similar exhaust. Not including performance exhausts.

 

I know  the OE exhaust is generally excellent, I just wonder how the non OE standard exhausts fair?

 

thanks
