tell me about supertrap exhausts

[Beezil]

my suspension project(s) have caused a nasty clearance problem for when I go to route the exhaust.

some of you folks suggested I look at super trap.

I took a look at summit racing's site, and was amazed but the large number of options there....

so i was looking for first hand experience ont he subject....

I'm looking for QUIET!

strange to me that one would reduce the number of discs to achieve this, but I'm wondering which product to choose....

there is one that is a mega-short attatchment that goes on the end of the exhaust tube, and there is also a 'full length' "standard" exhaust assy....

any input?

I think you should just install the header upside down and run the pipe out the hood and over the cab!!!

Mark is there a jeep forum you aren't on that I could go get some peace and quiet?

jackass! (I love ya though)

seriously, I'm thinkin about popping the exaust through the floorboard, going through the rear bulkhead, and popping on a supertrapp where the spare tire used to be. exhaust exiting just above the rear bumper.....dig it.

Well you can make the Supertrapps as loud or as quiet as you need. Easy to change as needed.

No experience on XJ's though, but they work on every application I've seen them on. Most of the time they have been the small one's on the end of the exhaust for formula type cars racing under a noise restriction.

 

[AJsArmor]

I've had them on both motorcycles and cars, the shorties are louder than the full length since they do use a packing material inside the tube. You are right on about how to make it quieter, the less discs you have installed, the quieter it will be. It's money well spent, top notch construction and you can tune them quickly and easily.

Used on bikes all the time. Makes good power. I've seen them on large motors as well.

How do they sound?

 

[Lucas]

I've only seen them on my friend's smaller engines (aircooled) and they were loud as crap anyway he tuned it. I think perhaps "quiet" may be relative to the recing applications they are geard toward.
But ive only seen one model, and perhaps the engine was just particularly noisy.

I'd run the exhaust through your cage, by the time it went through all that tube it'd be quiet. Use some header wrap to reduce heat.

another jackass......don't stand near any high ledges in Moab, Foreskin

 

[MaXJohnson]

Back when Brent was posting pics of his chop job, he included some of his floor mods. He raised the floor on the passenger side to accomodate the muffla. Couldn't you do something like that? Going inside seems a little EXTREME. Well... maybe that's why you're doing it!

The supa trapp you need costs $200+. That's the route I was going until I discovered this. The adaptor plate on the end of your exhaust tubing is NOT the way. It'll always be louder than crapola. Talk to the flower child, we just had this discussion last week.

OT,

Is this anyway to give Beezil crap about wanting to run a non-homemade muffler? Don't we all make our own? I have a homemade one, it's called "NoMuff".

Beezil,
Sorry if this has been covered...but, have you thought about running the pipe up thru the "bed" and point it up, like a truck?? You could then run a "normal" muffler.

No BS attempted here, just a thought.

I can't imagine that routing the exhaust tubing through the cab would ever be anything less than Loud and Hot, no matter what you did to it.
Here's a wild idea (cuz I knows you likes 'em). Get rid of your rock rails, and use some heavy wall tubing as dual-duty rock rails/sidepipes. You could slide baffles into them for noise attenuation. Between the baffles and the heavy walls, they ought to be quiet and would totally solve the lack of room underneath problem.

ZOOMIES,,,,,,, with 6 little rain caps on them to tell when a cylinder is dead....

 

[Beezil]

one snot....

200+???

where do you shop?

I can't even find a super trapp that cost that much....

honestly, I couldn't make sense of yuor last idea either. adaptor plate?

spit it out.

 

[XJEEPER]

Beez, WonTon, may be right ......... man that hurts........
I ran dual Trapps on a 4.3 V-6 with headers a few years back and here's what I recall........off idle and around town it was OK as far as noise level, but on the freeway and under throttle, it sounded like a Formula 1 car no matter how I tuned them. They are a tunable glasspack in simple terms.

I did notice a marked improvement in torque when I switched over to dual 3 chamber Flowmasters about a year later......and they were much quieter than the Trapps too.

Did you try Spintech to see if they have something that will fit? They specialize in low profile muffs, oval tubing.....racer stuff. Mil runs a Spintech unit on his XJ and it sounds cool, he makes 275 hp and gets 40 mpg.........would I BS you?

 

[rockwerks]

There was an XJ here in town with the supertrap on it and it sounded just like my flowmaster....not a note different. it worked really well was cut into his rear bumper to keep it out of harms way..built a heat shield for the floor pan all teh way down..header to tube to super trap on the end...
