what size of pipe is coming into the stock muffler and what size is coming out of the muffler. my brother just got his 07 and wants it louder, he's not very mechanical so i'm gonna buy him all of the parts, but i need to know what size of pipe and clamps to buy. i told him if he doesn't like the sound he can always put the muffler back on of get a flowmaster series 40.

 

cmon someone has to know what size the stock pipe is

 

i belive your stock pipe is a 3" pipe.

 

Perhaps few of us really have a 07 so we don't want to post bogus info

It should be 3" in 3" out...

It would only take about 15 seconds to check on the actual vehicle...it is either 2.5", 3", or 3.5"

Zero muffler will be a real waste of time and definitely will annoy all the neighbors... not to mention the V10 sounds real nasty with and open exhaust...good luck

 

3in is pretty big exhaust for a NA gas engine i don't see why it would have any negative effects on the truck besides annoying the neighbors. i know on a turbo diesel a 4in pipe is good for over 600hp. thanks for the help i can't measure the exhaust myself i live in ohio and my brother is in miss.

 

I have an open exhaust and it doesn't sound that bad, I will be changing though to a new y-pipe and flowmaster muffler

 

your going to hate the sound of that exhaust with no muffler....trust me

i put mine back to stock 15 mins after i installed a nice mbrp system with a muffler, it literally gave me a headache after a short ride....

the 05 and up 3v trucks have a different cat and xhaust setup....they sound alot worse than the old 2v trucks

its 3" pipe btw

 

thanx for all of the help guys

 

just do what everyone does and have your brother take it off and see if he likes the sound if not toss a muffler back on.

 

If the 07 is like the 05 (it should be) try this. Loosen the clamp closest to the muffler. It should be a band clamp. Pull the pipes appart and secure the system with wire if needed. you now have an open system. Take it around the block a few times to see if you can live with the noise. On my 05 the inlet is 3" and the outlet/tailpipe is 3.5". Here are some pics of a Dynomax muffler I put on my 05. http://rides.webshots.com/album/55030791FidJq

 

yours is the only 3v v10 ive ever heard of that has a 3.5 inch tail...where are you getting a 3.5 tail from?

 

I have no muffler and I like the sound its not loud at all only when I hit 3 grand on the tach does it bark and the bark is good

 

yours is not an 05 up 3v

 

If you look at this pic you can see the 3" piece I added to the 3.5" tail pipe. It fit inside the tailpipe and I had to bend/shrink the tubing to weld it up. The tip I bought was 3.5" inlet also. I dunno why I have that size pipe.

 

weird.....
