mine has the flows on. so i wouldn't know. just hit up a decent muffler shop and they can hold the piping up for you to hear before you bolt/weld it on.

Does anyone know what a 3.9 sounds like with a high flow cat and no muffler with piping out the back.
It will be loud... like setting of car alarms with ease. I have the stock cat and no muffler on and it's pretty well... loud. Im going to be getting rid of my cat and putting a muffler on mine soon hopefully it will quiet down some. My piping stops about half way down the bed too.

3.9 with hi-flo exhaust

Dont know what that would sound like. I used a cheap cat-back exhaust from JC Whitney, Y pipe off cat and mufflers at end of pipes, sounded like doo-doo. Got a Flowmaster 40 with single in double out, cut Y off other pipe and put flowmaster inplace then cut mufflers off the pipe ends. Bent pipe ends down and tipped with chrome tips and tacked em on with a welder. Most people thought it was a V8, great sound and still passed emissions. Got sick of the V-6 and swapped a 4.7 ltr in and left exhaust the same, Great sound and performance!!! :biggthump

try driving around with nothin but the manifold and down pipe on. Thats friggin awesome! All you gotta do is crawl under the front of ur truck and undo the pipe clamps and slide off ur exhaust. it works for me and its loud as hell. The panels in my truck all vibrate when its just idealing!
