Just thinking out loud here. I was looking at the HT3B I just got (wow it's large) and it has a 5" outlet. I hear that on the four wheel drives a full 5" exhaust is a little difficult to do, so I was wondering if you could just have the exhaust exit out the side past the front wheel? I imagine it would be very loud.

 

you probably wouldnt like the noise of that... but heres a post by unixcowboy of his exhaust that goes down the frame-rail. i thought it was pretty interesting.

3b's are quiet in twins and have the nicest whine/hum to the exhaust and compressor. They just sing. That being said a 4" exhaust will handle all you can put through it. 5" is not an absolute necessity.

 

I don't really want to go to a full 5" exhaust. If I can reduce it back to a 4" exhaust, I would be ok with that.

 

You would be fine doing it that way

 

RonA has put 9xx hp to ground with a 4 inch exhaust if I'm remembering the right person...

 

a good friend of did it to his ford it comes out the side of his body pannel right in front of the rear tires,the only thing is the smoke turned everything black past that point black including his nice custom rims,he changed it all after he noticed that,just something to think about.

 

X2 a local guy here has afirst gen with side exit in front of the rear tire and his hub cap is always black

 

Well I dont even plan on getting half of that, so the issue seems to be settled. I was just a little worried that since the outlet on the turbo was 5" you couldn't reduce it to 4".

 

I have 5 X 4 on my set-up with no problem..

 

I'd like to do that, if I could bring the exhaust out OVER the frame. I'd probably rip it off going under. Make room for another fuel tank where the muffler currently resides.

I bet 100 gallons of fuel on board would make it ride better!

I had mine out the side for a while, and it turns everything black and it bubbled the paint right by the exhaust from the heat (not that I am worried about paint)....it's out the back now.

 

Mine exists out the passenger side in front of the rear wheels. I have running boards that is goes under. I've had no issues with heat and being a dually I think that's why I don't get much soot on my wheels or side of my truck.

 

I've got mine ran out the side of my dually and it blacks the wheel out. other than that works fine.
