Straight pipe on a NHC-250

[StreetbikeDepot]

Has anyone straight piped their NHC-250. I'm debating on it, just can't find any hard facts on how it will affect the non-turbo motor.

Does anyone have any knowledge on non-turbo diesels and the affects of low backpressure?

Bring your earplugs along......N/A diesels are LOUD without mufflers.

Nothing personal, but what is it with the straight pipe questions around here lately?? You can put a straight pipe on pretty much anything but why the hell would you want to?? Almost any MV is plenty loud stock, there is a reason that putting a muffler on is such a popular mod. Do as you like but don't blame me when you can't hear squat.

I'd jack it up and put some big mudders on it too.....

im gonna lift it 27.5 inches... take off all the exhaust... put the naked chrome trucker girls all over it and the stick on bullet holes

Thats what we thought you were getting at.

You forgot the chrome lugnut caps.............oh, and the dual glasspacks.

alright, to answer your question.....my muffler is rusted out, thought if I was going to straight pipe it I would do it now. And NO I'm not throwing chrome stacks on it.....just a flex pipe in place of the muffler.

I don't mind the sound, heck a duece is twice as loud of my 818.

I was thinking more on the lines of slighlty lower EGT's in the case that I decide to turn it up just a little.

Whew! Thank God that's resolved. No chrome!

I do know that without a turbo, diesels are very loud without a muffler. Way louder than a whistler "C" if that says anything.

I guess it wouldn't hurt for flow though.

 

[coeder]

It should not hurt the truck at all

you had me scared for a min there.... but really all joking a side I was thinking of removing the muffler on my 813 also. But the N/A diesel is SO LOUD! when I do replace my exhaust (really soon) Im going to ditch the muffler and put it on the stack. Im sure the stock muffler is $$$$$ and where to find it like the sock i lost in the dryer.

I was told recently, the mufflers are about $450(Memphis Equipment).

I have a straight pipe on the 816...it was done out of desperation since I had to move the truck quickly from where I was making repairs on it. It is LOUD and as soon as I get my federal bailout money I am going to put a muffler on it. If I can figure a way to do it I would like to have twin stacks since I think any big truck without them looks lopsided.It sounds like a logging truck going down the road and I wear my hearing protectors at all times.Deuces came without mufflers but a lot of SS members have added them for different reasons.Since a turbo is considered a noise suppression device in many areas you won't catch flack from the local LEO's.I prefer a mellow rumble rather than a roar.

 

[StreetbikeDepot]

Yep, I bet that stock muffler isn't cheap if it can even be found, I don't want to put an external muffler on it since i want the original appearance to stay unchanged.

Gosh I can't believe you guys thought I was a kid trying to "bling" my truck.......

Everyones definition of loud is different......have any of you owned a Dodge 24V 5.9 cummins that was straight piped? I do and it sounds great (ofcourse it dumped at the rear of the truck....LOL), people outside hold their ears when I throw the coal to it though!
