straight pipes

Just wondering if anybody has taken the muffler off of their boat and ran straight pipe. I have a 1993 SN. I have a good muffler guy around here who makes custom headers and I really don't think it would be a huge chore to do. Are there any reasons besides noise not to do this? It also looks really easy to switch out if you ever wanted to put the muffler back in. I just really like the sound of the older boats.

Any thoughts or experience on this?

No mufflers on mine...sounds great.

Might be just me but on Vintage boats sounds great, on new boats you just wonder whats wrong with it. It will sound like a clapped out budget Ski Centurians that came without mufflers.

anyone have pics

Yeah, I know it would be a bit loud, but lets face it....it's cool. We vacation at the Ozarks so there is no problems there. About the only place where I would be concerned is in Minnesota. Ah hell, the fisherman hate me anyway. When I putt along it will just sound pretty. When I ski it will be really awesome. I just don't have mufflers on any of my trucks!

I will be looking into this more during the winter. I am at the mercy of the pipebender.

Thanks for the input guys!

This is actually true- with both our rigs on the same ramp, with his truck just idling, I could not tell if my boat had started or not. I ended up cranking it over twice since I couldn't tell the boat was running. That tow rig is LOUD.

It might smell when it starts to melt. I used 3" ID Goodyear double wall wire reinforced rubber hose. Good for 450 deg. and 150 psi working pressure. Skidim's got something similar but its awfully pricy after shipping. Got mine dirt cheap from an oil field wholesaler at 7 bucks a foot or so. Mufflers are a non-issue as they should be on anything a man drives. For those concerned about "politeness" buy a box of ear plugs and hand them out to the girls on the lake. Any boater who complains about straight pipes should find a muffler to install on their mouth. Straight pipes on the rig are also highly recommended. First you hear the 6.5 TD howl and then you hear the 454 roar. vroooom!

Newer boats (1989+) only have one muffler- a dual inlet/single outlet. All hosing is run inside the main stringers, rather than outside on the older boats, so its not a straight shot down and back. Removing the muffler isnt quite as simple as running new hose in its place or running all new hose front to back.

Thats exactly what it would involve. Send Randy out my way!

Can you get muffler bearings and blinker fluid there?

Chris, I was kidding about sending Randy. I may or may not actually go this route- either way it wont be this year. I wasnt the one asking the question. I appreciate the vote of confidence on my fabrication skills, though!

Ken your out there. what they are asking about is a pretty straight forward mod to make and with a little searching to source the parts it would take any bending or welding to make it work and eliminate the muffler. From what I recall the muffler looking like you need a couple of elbows and/or angles, a tee section and a few short straight sections to get rid of the muffler.

here all you have to do is buy the pieces you need from these guys and I'm sure there are others that sell the same sh*t, but they sell all of the bends, h-pipe, silicone clamps and what ever other bullsh*t you need to replace the invetro mufflers on the newer boats with the single exhaust. Hell Timmy the rocket scientist that you are it suprises me you didn't already know this and had it on your christmas list.



supplies to replace muffler

look under tee, slicone and tubing and if you can't figure it from there then your f**ked because you wouldn't be smart enough the use a hack saw or screw driver either to install the sh*t.

Rhyan, my '64 is only a little louder than an Ozzy Osborn concert,but that is the way mine came. she has become fondly known as the old boat that sounds soooooo goooood!!!!!!!!!!! BTW i have a 400 watt stereo w/4 6x9 , when Jimmy Buffett is playing you get the best of both worlds;ROCK & ROLL........ boat dr

79 is just trying to share the love of LOUD, can you hear it ,if not it aint LOUD enough
