Question on White smoke after straight piping exhaust.

I have a stock 97 F-250 SBCC with 180K miles. Great truck but got sick of the exhaust. Had original cat, muffler, and flat DP. I ordered the Diamond Eye 3" DP to 4" straight pipe with no muffler. Was pretty easy to install after reading everyone's istructions about the firewall modifications needed. Truck runs much stronger, sounds great, and picked up about 2 MPG so it was well worth it. One thing I noticed is that it smokes a ton now on startup until the truck is warmed up and the smoking stops. (White Smoke)

I plugged the block heater in last night and started it this morning and there was no smoke at all (32 degrees). I am asuming that I was just getting more smoke beause I deleted the cat and muffler but wanted to confirm with others that have done this to see what they experienced.

Turbo also sound great now even at very low speeds.

More then likely the smoke is from the cold nights. Check your glow plug system to make sure that the they are warming the cylinders correctly before it gets colder out.

Thanks. I checked the glow plugs and they are all working properly so I am chalking it up to the cold nights. Especially since there was no smoke at all when I used the block heater.
