Pretty sure they'll be quieter and deeper.i have kooks long tubes on my car now with corsa extremes. i recent found a good deal on a full 3" kooks catback that direct connects to the headers. does anyone have any input or thoughts on the kooks catback? tone? loudness? drone?
Deeper tends to create more cabin noise for the same exterior volume at the least, drone at the worst. It may not make your head want to explode, but you'll hear more.drone vs the corsa?
