I broke 100 miles today so I did a few pulls to redline. Felt way more solid than the ND1s I've driven, especially up top. Very noticeable difference.
When I got home I installed the GWR race exhaust, I was tired of how boring the stock exhaust was. I didn't expect any difference as I mentioned above, but it definitely makes more power. Feels even more solid up top and smoother everywhere somehow.
