Check out Zippers.Was told by a very good v-twin mechanic on the other forum(v-twim forum) theirs was the best bang for your bucks.I also have an 07 Heritage softail classic and asked the same question.By the way how do you like yours?Just bought mine (used 8000 miles) and i live in northern Maine.Be a while before i can ride.I am going with,Rush mufflers(2" baffle) t-max auto tune and Zippers air box for now. Peace and Prayers
I have a Big Sucker with a Zippers big filter installed on a 08 Fatboy. No problem here. But now I would look close at the "JET" backing plate with a Zippers big filter. Jet has a built volicity stack, looks interesting
