ok did the cat delete on the sling and as I figured I can smell the exhaust fumes now. I have the 2017 with the factory ripper windshield and the bullet speed top. I have read alot of the threads on this and was wondering if anyone has tried adding a vent to the windshield to help with the problem, such as the goldwing type or polaris razor type. if so would one in the middle be enough or would two be better, one in front of passenger and one in front of driver. using the vent on the goldwing that I had really helped in more ways than one. thanks for all info in advance also did the flap things inder the slingshot ever pan out
