Looking to put a new exhaust on my 1993 7.3 idi. Other than a lift the truck is all stock. It is originally from factory a non turbo engine but I have a good stock turbo and all the needed parts that we will be putting in the near future. What size and brand is a good one to go with? Not looking for stacks, don't want to be cutting holes in my box and straight piping it isnt an option either. Also, anything else I should be considering when putting a turbo on the motor? Already have the boost and egt gauges ready to go in with the turbo

 

I went to my local electricians where house and got 4" conduit.
100 bucks for 4.5" OD actual size.
10' length and a 90* bend

 

I went with a duramax walker straight thru high flow muffler. Took my EGT's down 200 degrees.

You could go with a 2' long muffler for $2 more if you want it quieter. Should be under $100 all in.

 

That made me laugh! I guess it works, and will likely never rust out.... Little heavier than needed perhaps.

 

If you put the stock factory turbo on it, just straight pipe it. Go with the stock 2.5" exhaust back and call it good.
Just make sure to run the exhaust all the way back and out. It's much quieter if it exits out from under the truck.
Also, adding the hump over the wheel will do some quieting as well.

The turbo(especially the stock factory turbo - Banks trucks are a lot louder) quiets it down a heck of a lot.

If you run it NA, get a through-flow glasspack type muffler. I used a Jones "Full Boar" muffler, and it worked quite well on my other truck.
