So I just switched from a Lethal Performance Resonator Delete X-Pipe to the Corsa Helix today and I'd say I'd agree with this to a degree but I was looking to make mine less deep quite frankly. I'm absolutely thrilled with the sound. That being said, I'm selling my Lethal pipe that has only been on the car for about a week as well if you're looking for another option. I found the lethal pipe to be deep, and for me, maybe too much bass for my taste.Anyone notice with the corsa x pipe that it sounds more raspy/lighter and not as deep? I am not sure its the same sound as a GT350 R. I am thinking a single X pipe would be closer. Any thoughts?
