dual 2.5" cat back no muffler and then 3" stainless tips at 45 degree might be H pipe dont remember if you would like i could get you some pics in the day time and post them on here

 

The key is the right sound, not the annoyingly loud, redneck sound.
For flow, we're talking about a 4.7L, not a 440ci, too big of pipe means you won't have the proper backpressure, causing you to lose the low to mid-range torque. Better top end, but less pulling power at low RPM, as well as affecting performance in areas with a lot of hills on the roadway.

 

i don't know how different the 4.7 exhaust is form the 5.7 but I went to autozone and bought a 3" extension pipe 18"long that was flared at one end to make up the difference from the oem muffler. The stock muffler came out pretty easy with some pb blaster and a hammer to break it loose.They have some 2" hanger clamps I bought and just hammered them wider to fit a 3" u bolt clamp. I used one on each end of the AT3030 and it doesn't move around at all. A couple of those in the stock hangers and some u clamps and it was in. I left the stock resonator which gives it a nice rumble but is not loud at all. If you want it loud just don't use the resonator. Save your stock tailpipe in case it is too loud.good luck

 

if you have a 4.7, remove the muffler and weld in a straight tube for best performance/sound. i had that done to my 5.9 for $30 at the local muffler shop. sounds great.

 

ok so you wanted to see what my set up was i figured it was just easier to upload a video in the day time oh yea and the ticking noise is just the ice resting on the tips http://www.youtube.com/watch?v=3Uu227FzzRs

 

thanks ryan for the video.in ma i dont think its legal to drive with no mufler.im gonna do the at2525 and try to ind a y pipe premade or ill have a shop make one.i may or may not leave the stock resonator,not sure yet.

 

love the video. the sound of a 360 with no muffler is perfect. and removing the muffler does not affect emissions johns, but it will add a little HP and MPG. nobody will ever pull you over for not having a muffler, i promise you that. ive had dodge ram's for the past 9 years now as one of my vehicles, and all with the muffler delete. i've lived in MN, IL, CO, and CA. No problems anywhere. Besides, you will love the sound of it.

 

i went to 2 exhaust shops today and they both wanted $200 to make and install a y pipe for my truck,no no no.not install everything-just the y pipe! they also both told me to just keep the stock y and not replace it. this sux,i have my areo turbine coming in the mail but cant find anyone to install this stuff for a fair price.

 

Wow. When I bought mine I took it to a local shop and the guy charged me $40.00. That was for a chrome tip, welding the tip on, removing the stock muffler and welding the Aero on in its place!

 

Keep shopping around or find a friend who can weld! Look around for smaller mom and pop shops, I bet they would do it for a good price!
