Magnaflow 18" or 14"

I think I've decided on the 18"

 

get the 18 for sure. or even the 22 will have some decent output when on the gas

 

So I want the chambered one but I want to be deep and broad, the video of the 18 manga flow seemed to crack and get high pitched, any other options?

 

The clip I posted was actually the straight flow 18". Magnaflow also makes a chambered one but I can't find any clips of it.

Could I fit a chamber muffler on the v6 without much issue or?
Also what size would I need? I.E. 6" or 7" chamber

 

Best way to know for sure is to poke your head under the truck and take some measurements. The factory muffler is already pretty large and I have an ext cab so there is plenty of room to run any of those. Either diameter will be fine, the 6" is going to be slightly louder

 

Same here . I'm just worried that the chamber would hang low because my offsets are up and down not side and side...

 

*eye twitch* you would rotate the muffler so that the offsets line up with the existing pipes
