Does it matter if mufflers exit the side versus the back?

Postby labloverdc » Thu Jul 09, 2009 5:19 pm

We're adding mufflers to our non-muffled BBC, which currently has 3" stainless flex pipe coming off the headers and exiting the side. It would be far simpler to just cut the pipe and install the mufflers so that they still exited out the side, but maybe a little higher above the gunnel than the pipe is now. Is there a big disadvantage to doing it that way, versus cutting the pancake cage and making it exit out the back? We're using stainless steel Magnaflows if that makes any difference. Thanks for any input.

the only down side (that i know of) to exiting out the sides is saw grass. if you get hung in dry sawgrass you take a greater chance of lighting a fire versus coming out the back. the only other thing is they get pretty beat up on the sides depending on what you run.

I dont see anything too bad about it, chances are ill be running mine that way, straight out the side mounted on a pancake cage.

From a sound point of view, it makes sense - to some degree. With the sound going out the side, never will you have both your exhaust's sending sound in any one direction. So at most, you'll only have half your motor's sound heading towards a complainer.

Muffler out the side is like the tail pipe on a Motorcycle sooner or later someone will bump into the pipe but they will learn, it usually takes one time. Also the grass building up when you are running the rough stuff.

I heard something last week that I thought I should share with y'all... I recently went to court over my exhaust (and won by the way :) ). My exhaust runs out the sides but the officer I was in court with started talking a lil off subject, and he mentioned that exhausts that go through the transom are being considered illegal...?

That officer is completely wrong and cannot show you a thing to back up his wrongful assertion.

WOW............ Even ocean, river, ski boats have thru hull exhaust........ Someone needs to call SeaRay and tell them to stop production !!!!!!!!!!!! :scratch: :scratch: :scratch: , I have heard of off-the-wall stuff, but that one doesn't make sense to reason with......... Wonder where he got that one from..... He might have been just trying to cloud the issue in front of the Judge..
