straight pipe exhaust

Postby HawaiianPup » Mon Nov 17, 2008 11:50 am

I know alot of the big trucks do this, do any of you have this setup? how loud is it? would it be better to go with a flowmaster exhaust? Thanks for the help everyone

I have 1986 Trooper that last owner inserted a straight pipe where the muffler was. You would not know the muffler was missing unless you looked.

my diesel is straight piped right now and it is pretty loud, 82 4wd. I bought that way and have gotten around to changing it yet.

Turbo makes a big difference in the "loudness", sort of acts like a muffler. A non turbo will be a lot louder.

My 2.8 diesel w/turbo isn't loud at all with 2.5" all the way back and no muffler. It gets kind of throaty when accelerating, and the turbo sounds awesome, but it's not too loud. I think it sounds really good. My friends say it sounds like a mini-semi when I'm going down the road :mrgreen:

My 1986 c223t diesel just had exhaust replaced by 2-1/4" with straight pipe from the flexi section all the way back so no more muffler. It sounds kind of like a bus especially when you go though the tunnel or passing other car with windows down. The rev seems to pick up quicker and has abit more power, I can pull it up a long hill at 120km/h easily now (maybe just a feeling)

It would really sound good if you have straight exhaust and installed an exhaust break on it like Paul has. 8) It isn't Jake Brake, but would still sound good.

Hey Andy--

The exhaust brake works pretty darn good but makes only a little noise, unlike a Jake Brake. I do have a muffler though. Maybe I should take it off.

I used to drive a Volvo FE6-13 straight truck that had an exhaust brake. It had a similar sound of a Jake Brake, but not quite a deep. It was a small 6 cyl and had a muffler too. It was actuated w/ an air cylinder at the damper in the exhaust and air supplied by pushing a little button on the floor w/ your foot about he size of an old style dimmer switch. I used to hit the button real quick while keeping the other foot on the accelerator. Black smoke would billow out from under the truck. Very handy in getting tailgater off my back. :wink: :twisted:
