Gutting the cat

Well if i end up cutting off the 2nd cat, can i gut the first one while its on the truck, and will this sound good with a glasspack after the first one with a turn down.

It will be pretty loud. I like mine, cut off the second cat and 3" pipe all the way back. Try that first, you can always take off more, but it gets expensive to add stuff back...

300s arent that loud. The more powerful an engine, the louder it is. And 300s are not powerful. When i did exhaust on mine, i started it up and revved it just for the hell of it while it was without the cat and muffler, and it really wasnt that crazy. Too loud to be driving around town in, sure, but not waking the dead.

Id just flat out get rid of the cats if youre going to do the work to cut them out in the first place. unless youre gonna get a visual inspection or something. I have just a 2.5" Dynomax Superturbo (no cat) on mine and it sounds better then the pathetic stock JUNK...but its not significantly louder than stock. And the superturbo is actually a muffler. the stock "muffler" is just a resonator. mine was, anyway.

ditch all cats and straight pipe it all the way back, no muffler. The 300 is a low revving engine so you wont be rattling any windows but it will be a nice low sound

I dunno if I would straight pipe it, I have heard some people on here say it sounds good at low rpms then, gets pretty ricey up at high rpms. I dunno that turbo muffler is probly what I would do. On mine I took off both cats and just put on after market muffler, it sounds pretty good for a 6. It has the "old truck" sound to it, I like it.

Got my 1966 f-100 muffler fixed yesterday. Just went with a 24 inch glass pack. Told them I didn't wan't it to sound annoying. Well you can hear it but not very much. Will get better as the glass pack gets older.
