I've got a '97 T600 with a grass burner muffler underneath that I'd like to possibly convert to a dual exhaust system with a better flow-through muffler for more power and better fuel mileage. I have a full-width headache rack on the back so I guess I'm looking at going up the sides behind the doors or even better, is there a way to mount the pipes down beneath the side-skirts with turnouts? I'll be trying to do a lot of research on this on Monday or Tuesday, but thought I'd throw it out there anyway, just in case anyone's already been through it.
T600 Grass Burner muffler to stacks

External side pipes may add power, but they will cost you mpg

The reason for the weed burner exhaust is air flow..shorter pipe to travel
true blue Thanks this. -
Do it for looks only .. Every bend you have just adds restriction my guess is at best you may break even on flow with hi flow mufflers but I'd doubt it.. Most likely you will lose a couple tenths
true blue Thanks this. -
The ones I've seen have used a section of square tube to pass between the cab and side-skirt. Appears to be prone to cracking, likely doesn't flow that well, and in my opinion looks kinda cheesy up close. But that is just my opinion, and you might find a better way, or a way to make that work for you.

If you want the stacks for looks then get the widest available and the less sharp turns the better, also to gain more power try to get a free flow muffler or if you wont get in trouble straight pipe will be even better for power gains, now if you are just going for the look only, don't bother with dyno and ECM programming, but anytime you mess with intake and exhaust it's best to dyno your truck before and after and also reprogram the ECM.

I used to have weed burner on my t600. I placed universal exhaus stack behind. Looking on to replace oem with kenworth exhaust stacks, remove pto blower, place rear duel 6 in stacks, and replace the muffler with walkers megaflow.
true blue Thanks this. -
I'm gonna look into the difference between the Donaldson and the Walker tomorrow,2/12/14, and see what I come up with. I'm glad I saw the post somewhere about the Pittsburgh Power muffler being a Donaldson Hi Flow muffler with the PP name on it.
