Muffler / silencer recommendatoin for tri-mil

[waterman7474]

This might belong in the engine forum but here goes anyway.

My baja is in the process of a remodel and getting a fresh 1776 upgrade. The motor is being heavily built on the premise of reliability (don't have full details on internals yet). He is putting on a off-road tri-mil but without any silencing and leaving it up to me as to what to add to it.

I have read a bit about supertrapp clamp on units but i'm a little concerned about noise. While I don't want an full open pipe, I don't necessarily have an issue with it being too loud, but this build is being set up so that I can take the family and have a 3 and 5 y/o and "BLAAAAAAA BLAAAAAAAAAAA" might not go over too well, pretty quickly. That being said, I don't want a full "quiet pack" either and just because the motor isn't wrung out for power, I don't necessarily want to choke the life out of it either. I do need a spark arrestor out here as well.

There is also the high possibility of getting some paddles and heading to the dunes.

So, recommendations?

Thanks,
flynn

Turndown with some kind of turbo muffler. Or a small flowmaster or magnaflo.

Definitely something that turns down anything that is point up will be a water catcher....... In national forests and most off road parks you will need something that is a approved silencer or spark arrestor...

Glass packs are the only thing in between a Supertrapp and a quiet pack, but they are not forest approved. Just go with a quiet pack. VW engines are naturally noisy so you'll still hear it.

Correct me if I'm wrong boys, but wouldn't a flowmaster meet the Rangers specs? Good enough for a full size truck right?

I put a 4" diameter 18" long supertrapp on my 2332 turbo, and that turned the volume down quite a bit. You can add or subtract discs to adjust volume and flow characteristics too.

Maybe a two chamber flowmaster. I think the 10 series would be a little loud.

I ran my 2276 with trimil and turn down to a summit racing turbo style muffler. I have also used the chambered muffler (its slightly louder). For the price its worth a try. https://www.summitracing.com/search/brand/summit-r...=Ascending

I used the long s/s muffler from empi then welded a sprint car super trap on the end. Not too loud and can go to any state park with no problems

[weasel_ugs]

I use a 2 chamber Flowmaster attatched to the pipe from a baja quiet pack muffler. You will want to put a turndown or something after the Flowmaster to quiet it down some. Look at the blue buggy in my gallery.

As I have suggested before. A downturn bend on the collector and put on a 2" Thrush Turbo muffler.

- Meets Forest Service and BLM regs.
- Moderately quiet.
- Lightweight.
- Inexpensive.
- Readily available.
- And sounds cool too.

Hate to revive this but why not go with the trimil muffler or glasspack? I have the stinger with the baffle in it and I'm about to order either the glass pack or the muffler from them.

I too have the tri mil stinger on a buggy. At first it had no baffle with a spark arrestor. In this configuration it's stupid loud and wholly inappropriate for the street. Next I added a baffle. This shut it up some but it's still on par with some attention craving dentists Harley AKA still way too loud.

So as soon as I find a suitably sized muffler I'll be doing the 180 degree bend thing.

I run this on my fiberglass manx style buggy.... I can actually hear my Weber going "full tilt" over sound of my exhaust...

I had glass packs on my '97 Mustang. Took it to a shop for an alignment. guy drove it around the block, I heard an incredibly loud car. Thinking "Get a muffler motherflogger" and my car comes around the corner.

took it straight to Midas after the alignment. Flowmaster C 40s. Basso profundo rumble, not loud but sounds like a POd panther.

When the fiberglass burned out the tubes in the glasspack that held the fiberglass clanged around like bells. drives you nuts.

as noted above, a turbo muffler as used on Tri-mill bobcats works great
