Hey yuana, what type of conditions do you ride in? If you ride in dusty, wet conditions let me know how you like the pro design intake. I'm thinking of getting one but I'm still not sure if I want to trust it without the lid on.
I ride in pretty much dusty conditions because it's pretty much summer here 365 days a year and always hot and dry. I'll have to check the wet conditions in October when the hurricane season starts. But I'll let you know how it works out with the dusty conditions first.
Took out the Sparky today to test the sound levels but damn that was loud and cool sounding.
Very easy to remove the sparky by the way, 3 bolts to take of cover and 2 bolts to take of the connector behind that and remove the sparky.
Love the sound of this pipe with or without sparky it's real throaty.
