Exhuast flow not smooth

[Accordlx]

my 93 cb has 196435 milez and when put my hand near muffler to check exuast flow..cuz i know sometin its wrong...it flow out rough lilke car go over bump..its not smooth...and I can hear it goes bup bup bup from rear of exausdt when i press a gas slowly and easy.

Don't quite understand what you're describing...but perhaps the muffler has a leak, or could be the engine not running right, which can give odd exhaust sounds.

[f22a4accord]

is it the stock exhaust? LIke what was said above, hard to understand the question

[pretty_ricky302]

if ur hearing poppin noise i would stay air is gettin in there, mine does it alot b/c my header downpipe is blown so there no seal there

[wed3k]

isnt the popping noise the engine missing?

wha?

i would say you have an exhaust leak somewhere...maybe an exhaust gasket missing from a connector piece in the exhaust..or it could be your header leaking...you'll have to explain to use a lot more about this problem for us to come up with a sound explanation.

im betting most likely though its a leak between exhaust linkages. how long ago did you get your exhaust replaced?

[Durrby]

like everyone else said it must be an exhaust leak...first thing that came to mind before seeing the thread.

If it's stock maybe you have a rust hole somewhere after 196k miles.

We need more information such as, is it stock exhaust, does it run bad (other then just the noise), is it rusty, etc. If you do not have a cat on it, it will tend to backfire because there isn't a whole lot of back pressure.

I donno if its the correct way of checking for leaks, but when i wanted to see if i had a leak, I took a paper towel and covered the exhaust, and it'll force the air out of where the leak is (if there is one).

sorry guys. my english is not good..its not about exhuast noise...what Im trying to say is that my exhaust flow is rough (unevenly flow out)...the flow is not smooth.

damn iono how to say this..but its like a fan blowing at u..u will feel an even smooth air blasting at u..my exhuast doesnt flow smooth out like that..but it cut and flow cut and flow unevenly. ..ya meean.

When you say not smooth when its coming out it doesnt feel like full flow? If you notice an increase in exhaust noise you could have a leak as specified. If it feels like not a lotta air is comin out and such could be something clogging the system like your catalytic converter or muffler. Hope that helps out a lil

[cooneyb81]

did you check if there are any places where its bent and its not supposed to be

[coletrain]

you mean your exhaust flows out in puffs, not a constant flow.

[Accordlx]

you mean your exhaust flows out in puffs, not a constant flow.

yes yes man thats ecacly my point...oh yea my exhaust are new..new pipe new+ muffler...I experience this problem wid my stock exhaust so i guess its not the exuast is the problem. mayb its the engine.
could it be that i need a Valve Ajustment.?

[NAiL05]

Thats how the engine naturally is. Your exhaust valve closes shuts the exhaust for a second or so then it opens back up. Thats basically somewhat what it does hence why your exhaust flow shouldnt be smooth all the time.
