rc components 4inch or 4.5?
Thinknive decided on rc components slip ons. (Already stage 1 plus cams) just can't decide between the two sizes. I like the deeper tone. My g/fs dad has d and d 2 into 1 and I hate the sound. Sounds empty and hollow. Loud is a plus, deeper rumble is best.

If you want deeper, definitely go with the 4.5's. And they look better too. I just put the RC 4.5's on my stock 2013 Street Glide and left the stock headpipe on. S&S air cleaner and a Power Vision tuner. Sound is a bit deeper but not that loud.

I just put 4" Rc's on my road king. It is stock and it sounds excellent. nice rumble but not obnoxious at high rpm. I have heard the 4.5" have a little lower rumble but i think it comes down to looks for the most part.
