More of a rumble on my F-150?
I already have the glass pack hooked up to my 1995 F150 XL I6. Its got a small straight pipe coming out the back already. You can hear it when you fire it up and hit the accelerator. I want more of a rumble when it idles, fires up and in gear. How big of diameter pipe should i get when i extend it all the way to the back? I dont want a fart tube so not to big, and also, would a resonator help at the end too, and how big of one wold work too?
