Interesting idea, Conn. That might even create a little vacuum on the end of the pipe if it were done right.

The soot thing would be a problem though...

i was going to put a slash angle 3 inch tip exiting under he fender with the exhaust opening pointing outward not downward.

like a 67 corvette 427 with side exhaust but just the tip really seen so it looks cleaner but i want to be able to look out the side mirror and monitor the amt of black smoke coming out of the exhaust

Out the side will mitigate the soot problem

if you have the money and u want the ultimate performance
If you going to do exhaust on a turbo car do the Turbo back I don't see much point going cat Back
I'll go with 3 inch but at the end of the day it's your car got 2.5 inch because the guy insisted on it so I took it to another exhaust company and got stainless steel /3 inch ballistic cats vortex exhaust
set up in your car
3 inch dp going into 3 inch ballistic cats going into vortex exhaust there the best trust me on this I know at the end of the day it the best you can afford
check out the vortex exhaust

Unless you have a california car, there is no catalytic converter on these diesels.

Adding a cat to a diesel is useless and will clog up quickly, which is not good for performance.
EDIT: gotta love spam........

The catalytic converter on my '87 has no clogged holes, flows well. Mercedes installed as part of the 50-state trap-ox replacement campaign many years ago.

Not from me at this point. As I said earlier, I had (and still have) a couple of other projects that have pushed this to the back burner. They are "need to do" whereas this is only "want to do"...

I don't anticipate having the time to do anything on this until spring - at least. Maybe early summer...

im still planning on doing this for sure but im going to wait til my garage floor isnt
100 degrees below zero. i hate working on a cold garage floor, and even worse when ur trying to get a rusted ass exhaust clamp or bolt off and it breaks when ur about to give urself a hurnea from using so much force to try to break it loose and u smash ur knuckles against the super cold metal.

HAH! At least you have a garage to work in. I'm doing a diesel transplant into a Jeep Cherokee in my driveway with a "tarp-garage" set up to keep the rain off me! And it rains all the frigging time around here this time of year...

Oh well, at least the temps are in the 40's...

Try gravel and mud out doors. You might better appreciate you horrible working conditions.

Consider a good kerosene bullet heater. Deflect the out put toward the floor with a piece of steel, and the floor is heated.

One word. Smoke Wrench. It has to be the greatest tool a shade tree mechanic can have. Not only does it give you heat to loosen bolts, but you can cut off rusted old clamps and exhaust parts.

I just finished installing a HX35 and a full 3" mandrel bent exhaust with a magna flow knock off called big dog it is made out of 403 stainless. The muffler is a 24 inch offset sitting in front of the rear axle and sounds real nice would recommend it. I built the exhaust myself just bought the bends and pipe from Columbia river mandrel bend. They were real help.

Any update rcounts or from anyone else on the exhaust project. I have a 87 300sdl, that is in need of a 3in full exhaust.
