I have a vance hines tuner I took off my 2011 roadglide. my tri glide already has reinharts 3.5 slip on mufflers and still has stock header with the cat and air cleaner. my question is can I install the tuner and hi flow air cleaner with the cat still in the header pipe? I like the way its sounds now and just want to get it to run a little cooler and a little less lean. I know I can decat it but I don't want it any louder than it is. thanks in advance from calif.
