Those are what I have... for me they were the perfect upgrade. I was looking for more sound and these definitely deliver. Sounds much louder overall and especially when you get on it + has a nice rasp with little to no drone. Well worth the $$ Fitment was about 9/10.
I think these would fit the bill for you if your trying to step down from the test pipes.
