m1008 straight pipe?

[jrobinson5093]

Its a different engine, but similar. I put one 3 inch pipe into dual 5 inch stacks on a 1986 f350 with a 6.9 IDI. It sounded pretty good and was loud but with the windows up it was ok. And I had no problem with back pressure.

Is there any functional purpose for these stacks on a pickup or are they in the same category as 32" rims on an 80s Caprice?

Hey... There CAN be function to a stack. I'm putting a stack on the XM1027 (CUCV Crew Cab), but the point is to elevate the exhaust, eject dust from the filter's precleaner, keep exhaust sparks away from dry brush, and avoid boiling the fuel tanks. Carving a chimney out of the back of the cab to accommodate it without loosing bed space - but I'm also putting in a resonator, a HUGE muffler (biggest I could physically fit, 51" long), and wrapping the entire exhaust from turbo to tip with acoustic heat-shield to stop pipe wall resonation. Your familiar flapper on the tip keeps the rain out, and if I camp I can put an extension on the pipe to get the exhaust fumes well above the camp (don't like breathing more exhaust than necessary).

That stack better reach the stratosphere. My wife and I can smell and hear a CUCV a 1/2 mile away. No escape from that rattling stinking sound and smell. Maybe you need to put a DEF on it and it will be a happier gentler CUCV. With the exhaust fluid system you don't smell any exhaust.

It is a Cummins inline-6, not an 8-cylinder baby rattle

This thread has definite potential. ��

I replaced the stock exhaust with 3" routed the same way and with no mufflers. Sounds terrible. I had the shop cut in some thrush mufflers and now it sounds great. Cant advise on 3" straight pipes with no mufflers, it sounded like a crappy rat rod.

And this is my 86 with flowmaster super 44s,2 1/2 inch with 2 1/2 inch tails.http://youtu.be/rnEEm.01xZQ I like the chambered flowmasters much better.

I wish I could add more muffler to mine but since I've got the downpipe running on the outside, there's only so much room under the floor between the rail and rocker. I've got the longest glass pack I could fit under there. At some point I'm going to re do the downpipe to snake in between the crossover and frame so I can run it in stock location and run a big ol muffler.


Turbo noises > exhaust sound

It's to match the stacks on his riding lawn mower Lol

If I wanted to do something cool and different,I would go with 6.5 turbo exhaust manifold on drivers side,then 2.5 crossover to a 6.5 turbo exhaust manifold on passenger side,then 4 bolt flange where turbo would bolt on to a 3" or 4" exhaust pipe straight up thru hood. Just a thought.

I have said manifold if you'd like your idea to come to life. Pm me if your interested

That would look much better than stacks IMO

And it would probably defrost windshield nicely also! It would be fun to do just because I havnt seen it done yet.

My m1008 has straight piped exhaust and I like it. I had my local shop install 2.5 inch true duals and some 4 inch tips that are about 2 ft long. I like the sound I get but I'm 17 9i like loud engines. The truck is no louder than my dads 2000 Chevy 3500 with 7.4L gas burner with some no name hot rod mufflers that don't really do anything. This is the only video i have. https://m.youtube.com/watch?v=NyAW-q7vsLQ
