I just received my BRAND NEW Jammin JP-1 exhaust in the mail today and it has a dent on the bottom side of the exhaust, directly on the opposite side where it says JP-1 on the exhaust, the dent is about the size of the end of your pinkey nail. From my motocross background...i know dents will cause a decrease in performance, me being new to RC, I dont know how big of a dent can actually hurt it? any feedback would be great, thanks
