Okay well guys, sorry to say but I just changed my exhaust tone completely...I had the most beast sounding exhaust on my truck, and got compliments almost every day. Not like a ridiculously loud or annoying tone, just a deep almost musclecar sound. Straits on a 4.7 sound way different than a Hemi...deeper, I dunno why

Anyway, I got tired of hearing the drone and went to a Magnaflow SI/DO dumped behind the muffler. Also put a magnaflow y on there. Anyway, it is VERY quiet, no drone and SUPER deep throated in a non gay way. VERY quiet though. So I just got through my first tank and guess what? I lost almost 1 MPG though, highway mostly. I reset my PCM and all of that (didnt know if I needed to) so just wanted to clear that up. But my low end has a little pickup for sure though, Im guessing my straits were TOO free flowing and hurt me down low but helped at highway speeds, mainly what I travel.

Just wanted to have an open thread for people searching...no pics, if yall need videos ill try but its not too different and you know how exhaust sounds through a phone/camera

 

i had straights on my 4.7 when i first got it and it sounded wicked, i would still have them if it didnt crack and pop (annoying), when i went to the cb extreme like u said i felt a lil more boost due to the free flowing exhaust before hand.... as for mpg i think i might have gained a little bit but then again that might be because i was a lead foot when i had the straights

 

I love straights on a 4.7. I havent ever heard one pop or crackle out of it. (maybe thats cause mine is from a cut out and not out the tips) When my cut out is closed it comes out the magnaflow si/do just like yours matt, and compared to straights it sounds like a prius

 

^^^^compared to straights it sounds like a prius....... hahahaha yeah i had them coming out the back, so in other words u had them dumped ram man? was u running true straights or did u keep the cats on, cause i kept mine on

 

yea i had my cutout right after the stock y and kept stock cats

 

wow the ur exhaust ends right under ur cab, i bet that is loud, all this talk about striaght pipes makes me wanna go cut my muffler off

 

yea exactly. but i want it louder, but dont want to lose the tone it has (no pop or crackling).....matt you need a cut out, i know that your missing the straight piped sound by now

 

yea I am, I was actually thinking about that as I was writing this post

 

Hand calculate that MPG, dumb over heard reading is crap.

I'll have my Glasspack on soon. I got the 30" body 35" total length.

Vids and pics for everyone...

 

you dont think after being on here THIS long that I would post an overhead MPG, do you?
