is your 240 being winter driven? I wanna hear that thing. J really love the deeper grumble on RB20’s. I find the Hi-Power is a really nice and straight exhaust, but it’s a bit too quiet. I enjoy that pronounced grumble just like I enjoy a V8. Having my car side-by-side with Ronnie’s, Ronnie’s idle overpowered mine. The prounced RB grumble adds soul, and the Hi Power tends to take away from that a bit. This is my own personal experience. It’s part of the reason why I plan on ditching the cat.
