Has anyone heard of and can vouch for the quality of the XForce extractors?

I've got a few exhaust systems quoted up, from a full DiFillipo, to a Bitza mix of exhaust parts.

ive got a 4.0L EB, and basically, engine-wise, (in a week), ill have a fully rebuilt engine, race pistons, new cam and balanced

this exhaust im looking at getting consists of Xforce extractors (an American company, coming to Australia, at the moment catering for only Falcons and Commonwhores, they are stainless polished steel) can anyone vouch for these? quality?
anyway, the rest of the system consists of a Magnaflow Cat, 2 straight through mufflers, and a 2 1/2 inch mandrel for the rest. $1100 fitted for the lot ($580 for the XForce extractors)
any comments? suggestions? or tell me what these Xforce's are like! Cheers

$580 forr a set of uncommon extractors, go the Pacey Comps, cheaper and you'lll find dozens of happy customers!

Its a risk yes, but what if they end up being better?

i'm not a gambling man, specially when your talking near $600, and if they were so fantastic why havn't we heard of them before?

mate they are one of best quality systems out there.
i havn't personly seen the I6 extactors.

but all of the others i've seen have be very nice.

because they havn't been around that long and no one has been looking

well ill tell ya what, ill do the gambling for ya engine goes in next week, so a couple weeks after that i should be getting the whole exhaust fitted... without being able to compare it with the Pacey's, ill at least let you know how it all goes... gonna be hard to tell a performance increase in extractors alone since ive got around $4000 worth of engine/exhaust components going in under a month, but ill do my best :p

Cheers

I think the reason they are so expensive is because they are stainless steel. So thats quite reasonable.

mirror pollished s/steel at that. all tig welded. pipe over like the pacies

I've spoken to a few exhaust places about custom extractors (nothing made standard for my car) and they have all told me that SS tends to crack and they'll only make out of mild steel for me.

i've worked on a few cars with engines that would create more exhaust heat than a jag. and the s/s pipes havn't cracked.
