Scorpion Quad-Tip Resonator

[davidb]

Being 101 degrees here in St. Louis today I took the
header, "J" pipe & resonator to the sandblaster
yesterday off my "new" Scorpion to paint outside today .
Well the MORON sandblaster did a great job on the
4 chrome trumpet tips too ! Plus after the sandblast
it appears the resonator had termites . Don't know
what brand it is: ANSA, STEBRO ? Before I call around
anyone of a source for a replacement resonator ?
Like I said, best way to describe it is those 4 "trumpet"
chrome crimped tips . Thanks .

Sounds like an ANSA system. The only replacement tips I've found that look like them are the Monza resonators. However, they have a much larger inlet pipe than the ANSAs do. See link.

Well it got worse 'cause when I more closely looked @ it
it has some healthy holes it in . I doubt the AutoZone
Versa-Chem exhaust sealer I put on will work [the
beige toothpaste] given the size of some holes .
Called C. Obert, Bruce & Vicks for a replacement [hah]
same response from all three : #1.) they laugh, #2.) they
said haven't been made for years, #3.) if you find one
it'll cost you out the pa-too-tee & #4.) said either make
one of it's the Monte Hospital .
:(

That's accurate information. They are just not available anymore. I suspect there may still be one or two new ones laying around somewhere but maybe not.

I stumbled upon and bought the last NEW one I'm aware of a few years back when I first got my car. I eventually sold it to Mike Ross out in California and got a stainless Croft system from the Monte Hospital.

Lot of folks go to the CSC system. It's VERY well made but I don't like it because it has a really bad resonance in the cabin at cruising speeds.

I'm still considering having a new system designed and built for general sale. If I can ever find the time...

Hell, I don't even have the time to finish getting my car back on the road.

[davidb]

Agreed : there's gotta be some left somewhere . Bet they'd go for $600+ .
Monte Hos. has a silencer [MH 5105] they say is ANSA, pipes/tips could
be welded to . But 172 pound sterling + the cost of welding, YIKES !
Think I'll start asking around @ muffler shops for ideas/prices :
Meinke, AMCO, Midas, etc . This is solveable short of spending $1K .
I stumbled across a web-site while searching that makes S.S. systems
for 308 GT-4's . Drop-dead gorgeous, $3.8K which is 10% of what a pris-
tine GT-4 is worth ! Here we go again w/older Italian cars: put $30K in
a Beta, it's worth $6.5K, $100K in a GT-4, it's worth $38K . We're all crazy . . .

Hi David;
You can mate up the ANSA header (your header is still good, right)? to the back half of the CSC. Mostly, people want the headers, so consider yourself relatively lucky. Tony Fasola had a spare CSC recently on the Lanciascorpion Yahoo list, see if it's spoken for.

If no luck, consider doing a crossflow from a Camaro appplication (Flowmaster 80 series) to the ANSA header. I happen to need the geometries for this mysrelf, so if your exhaust guy is going to start by rough tacking some bends to make a model, please save it/sell it to me after he's done! Unless you plan on having the whole thing done in stainless, then PM me, as I need one too! I have 2-1/4" twin tips with perf tube baffles that are ANSA, made for a Dodge Challenger and AFAIK you can still get them, although I got mine on ebay for about $100. Will make a Scorpion look like it has a 425HP hemi, heh heh...

I wonder if/how SuperTrapp muffler tips (click) (http://www.supertrapp.com/product_sections/auto/) might work for an application like this?

They're a clever concept IMHO. Entirely in lieu of a traditional muffler or resonator, the exhaust flows thru straight pipe all the way into a perf tube surrounded by an extra-long/-wide trumpet shell capped off by a stack of "diffuser discs". By adding or removing discs inside the shell, you change the exhaust flow/pressure/noise characteristics, either increasing backpressure and thus torque while reducing noise at the expense of high-end power, or increasing noise and high-end power while reducing backpressure at the expense of low-end grunt. You can even change discs on the fly for track vs. street days. Geez, now I sound like a shill, but really I just think it's nifty. 8)

As long as you have a good header already, then you'd just need to have some straight pipe suitably bent to route exhaust from your header union -- er um, I mean from the catalyst connected to your header, of course ;) -- on out to the SuperTrapp tips.Seems to me you might also be able to tune your actual exhaust note according to the overall length of pipe you've got twisted up in the middle like a tuba (perhaps this is the actual cause of that CSC drone DJ mentioned)...? I've been meaning to try this as a cat-back solution for a sportier exhaust on my Zagato, just haven't had the gumption (read: convergence of time, money and motivation) to realize it yet.

[davidb]

Yes I quickly realized if the header was bad [it's fine] things
would be ALOT worse . I googled "CSC mufflers" & didn't come
up w/much . Anybody got links ? It'll be a pain but the patched
ANSA w/the sandblasted chrome tips is going back on for now .
I could always paint the tips ANSA orange . Gross huh ?
:o

Here is a link to CSC http://www.csc-marmitte.it/eng/index.asp

[davidb]

Thanks Brad . Man that one for the Monte [Scorp] looks nice even w/one tip .
Gotta be a two piece unit in spite of looking like one piece . Be impossible
to install . Problem is I have a darn near perfect header, why buy an entire
unit ? Let the games begin: hunt, hunt, hunt for a resonator alone . . .

Tye;
Supertrapps are really track-only, they have a sharp, nasty sound that gets on your nerves right quick. They make even a glasspack sound nice by comparison.(IMO)

Also, the dorky thing sticking out of the ass of your car gets really hot! Some of the autocrossers around here use them. believe me, you'd tire quickly of running one on the street!

[SubGothius]

Just curious, have you heard any Supertrapps that you knew to be street-tuned (fewer discs)? I don't mean to naysay your experience, but with such a variable/tunable item as this, even several experiences in passing can't be taken as a fully representative sample unless you know how many discs they had stacked up in there. It's like saying "Webers make a bunch of intake noise" without knowing what kind of Weber(s), at what size, with what airbox/filter or just naked velocity stack horns, etc.

More discs would stick out the end more and get real hot as they allow more exhaust to completely bypass the perf tube and the sound-deadener surrounding it; fewer discs would be tucked back into the trumpet shell and force most of the exhaust thru the perfs and past the noise-cancelling material inside the shell. I reckon any encountered in a competition environment would naturally have been track-tuned with more discs for the most high-end power (and hence the loudest, harshest noise), and even street encounters may be suspect due to ricer types peacocking with loud exhausts and/or misguidedly going for Moah Powah without realizing that robs them of more streetable, boot-in-the-backside torque.

I'm just sayin', is all. 8)

Well, no, I haven't heard them in all possible permutaions, nor even on a FIAT/Lancia 2L. I think I have heard it on a SOHC because IIRC Mark Seelbinder's X had one, and I've heard them on a bunch of Ricers. Extrapolating from what I have heard leads me to believe you may not care for it, but opinions are certainly subjective. I presume the ones I've run across are ideally tuned optimally, so since I would want mine also tuned optimally, one would expect that they would be similar, if not identical. All of the Supertrapps I heard have a disticnt sound, just as glasspacks have a distinct sound from true mufflers and fart can tips have a distinct sound as a group even though they may vary in configuration and design individually. In the case of the Supertrapp, I would describe the sound as a sharp, high-pitched tinny blatt sound. I personally wouldn't want to trade a tenth of a second on an autocross course for driving around with that buzzing, but you may love it- they sell enough of the things that some people must love them, right?
