a friend of mine is looking for an exhaust and asked me to help... it is an '07 2500. he wants to put 5 in on it if it will fit... i havent looked at where the turbo is, and i drive a ford so i dont know. he wants it to come out right in front of the back tire in sted of going over the rear axel. im having trouble finding such a thing and was looking sugestions. dosent want a muffler.

 

Every one I have seen like that was a kit that was modified to come out like that.

 

5 wil fit, the exhaust before the tire is gonna be a pain though when its time to clean the truck

 

Our Expandit 4" Kits use a 3.5 Down Pipe on the 6.0 Powerstrokes.

 

You will not find an exhaust kit that exits in front of the rear tire. Also all kits will have a 4" front pipe not 5". 5" kits begin after the front pipe. Also there isn't a true turbo back kit on the market for the duramax. You can purchase the downpipes seperately from either Mbrp or Diamond Eye. Both are 3" and are a direct bolt on. If you have any other questions let me know.

 

magnaflow has the kit. but the down spout is from AST diesel i have the same kit on my truck and i love it. check ebay too. there 5 inch exhaust kits out there from magnaflow to mbrp. and more. prices run from 3500 shipped to 800 shipp depends on who made them. hope that helps. if you want it to come before the rear tire you have to modfy it your self. i dont recomend doing that it will change the color of your rims and its not easy cleaning them. if your friend cleans his truck every 3 or 4 days its ok i think. but if it get clean 1s every 2 to 3 weeks it will discolor your rims and sout is not the easiest to clean off after it sits on there for long peroids of time.

 

How much of a difference does the diamond eye/MBRP down pipe make? Lower EGT's, better mileage, faster spoop, louder exhaust/turbo whistle? just want to know the benefits before i spend 189 bucks on it

 

IIRC rttoys has one on his truck and i think he recorded a 75* drop in sustained egts while towing.


i cant remember 100% he posted it somewhere

 

how about sound wise? anything different. i got mine straight piped right now just wondering what it will do to the sound?

 

idk, he still has stock exhaust
