Looking for the perfect buggy exhaust

[VolkswagenGerry]

I will post a few questions here as this seems to be the most comprehensive exhaust thread I have found here..

I am going to add a baffle to my tri-mil sidewinder exhaust.
This baffle:
http://www.mooreparts.com/store/product/1043/Baffle-Trimil-Stinger/

Its sounds great wide open and all but over a long drive.. huh what?
Did you say something.. .. so I am hoping the baffle wil help some?

Shall I tack weld it in place inside tube?.. or slip it into exhaust then drill a pilot hole and tap some threads and possibly a allen head BOLT to hold the baffle into tube??
Will the thickness of the pipe combined with the thickness of the baffle insert lip be enough to hold threads??
Or... tack weld a small NUT into baffle lip and secure with a bolt.. same concept as above.. just more threads right?

Side note.. I have a ceramic exhaust and certanly dont want to mess up the finish..

Don't weld on the header if you value the finish.

I have used stainless steel rivots in the past with good results. Typically three around the perimeter. This way they can be drilled out and the baffel removed if so desired.

My drag race header had screws holding some parts together and they would need to be tightened every few passes due to vibration. I was turning 8500 rpm, but, over time, on the street it would suck to loose the screw(s) and the baffel shoot out/get ruined.

I came across this discussion, and have a question. I saw where andk5591 had dual cannons with glass-wrapped baffles and they were loud. Was that loudness with the glass wrapping?
I'm running dual cannons and been told wrapping the baffles in fiberglass or steel wool would tone them down some. I'm not after quiet, just want to tone them down a bit. Does this work, and will it do any harm to the engine?

[andk5591]

The glass wraps help until they blow out. I was getting muffler wrap from motorcycle shops.
Gonna have to remember to take a pic of what I finally ended up with on of these days. And honestly, if performance is the concern, you dont run dual canons anyway.

Also, it depends on what kind of baffles you are using. I got inserts with a perforated tub down the center and wrapped the oustide with the muffler wrap. Took the edge off the exhaust note.

See the thing is that if I cant have a conversation with the person next to me without screaming, its too loud. And after an hour or more, my ears just get fatigued.....

It sounds like what you did is exactly what I'm after: Just want to tone it down a bit so conversation would be a bit easier than it is now.

Is what you bought at a motorcycle show simply called "muffler wrap" and am I assuming correctly you wrapped the baffle, not the outside of the cannon? And, about how long did it last till it burned out?

I'd love to see your pictures

[andk5591]

Yeah - wrap the baffle with "muffler wrap" - its like a fiberglass sheet. Secure it with some wire. Lasted a few months.

You might consider adding a clamp-on Supertrapp disc-only series baffle with 12-14 discs to slightly baffle the noise...

As old as this thread is, it's a great discussion on buggy exhaust options. I wanted to add my experience/opinion to this great list for others to consider. My buggy was a sand rail, but this information would still work on a fiberglass buggy as well.

I was and still am dead set on using dual exhaust for looks and engine access. I couldn't care less about the claimed "power loss". I more than made up for this elsewhere anyway.

At some point in the 90's I think it was, Oregon added sound restrictions for riding in the dunes. I tried a number of different configurations, including the Supertrapp clamp-on "Disc-only" option that didget69 posted above (I used the larger 5" version, and I think I had it welded on though). This sounded great in my opinion and almost made it quiet enough to be legal. For me however, the problem was the additional weight and length. When riding wheelies the Supertrapps would dig into the sand.

The next and best option I tried, was what pitcrew posted above but without the crossover pipes. I simply bought a new set of dual glasspacks, cut off the mufflers and welded on the Supertrapp mufflers (black version). I then added additional clamps to hold the exhaust better during the rough ride. This was by far the best set up I ever used, and I eventually sold the buggy with this still on it over 10 years later.

Here is a picture of the dual Supertrapp mufflers installed. I wish I had a better/closer view of the exhaust, but don't.

I'm just going to throw this in so the info will be there for anyone following the thread.. For fans of the dual cannons, dual exhaust etc, someone now makes a stainless set:

As someone pointed out on a different thread, shipping is $99, but that still leaves you only $260 in a complete stainless exhaust if you like duals and if the quality is any good....

... maybe the pallet in the seller's ad foretells the tale of how long the quality lasts?

I just installed a 1 1/2" U bend. Sounds great, but of course is LOUD. Looking at these clamp on arrestors. Anyone have any experience with it? Pros/cons of each? Just a 1600DP.

I've used both styles & prefer the first option, as it uses a combination of discs and a glass pack baffle in the housing. Measure the OD of your U-bend to verify if it's 2".

I have that first option on my current buggy and it is a lot quiter than I ever expected, but still flows very well.
