polished the cans and painted the Y pipe and pre silencers. a little after school project..

cans say Trust on the underside and are stamped jasma. Y pipe is stamped jasma

Do any of you know this system ?

underside










top side

 

its a shame it goes on the car and eventually wont look that good after a few months/years lol

 

I want your exhaust so bad. I wish someone out there knew what the hell it was . I've googled 'trust exhaust' with various combinations of 'RX7, RX-7, FC3S, FC, 86-91,' for houres on end and still nothing .

 

dang for hours? i figure someone on this fourm knows what it is, the exhaust was one of the reasons i bought the car. its actually very quiet and it has a deep tone. but the tial waste gate with its stainless header is another story haha my buddy said it sounds like a cat ripping your face off, and my other friend named my car the badger lol

 

Greddy makes it

 

Good looking exh. man, maybe if you can contact Greddy/Trust & they could tell you something?

 

Greddy/Trust are the same company, amirite?

 

Greddy, Trust & Grex are sister companies from what I understand.

 

Maybe it's some sort of predecessor to the Power Extreme? Bah, what do I care, I don't have the money for a fancy exhaust right now anyway .

Anyway, looks really good. Sorry to knock the thread off-course.

 

from the late 90's. they also had the trust mx which had taller mufflers with slant cut tips. theres a forum member in here with the mx on a black vert with ssr wheels. and everyone also knows the late and great power extreme dual. Trust is the parent company, Greddy is the name they use over seas( usa. europe, south america). Grex is there braking , suspension foot work subcompany and Gracer is their aerodynamic line.

 

^^ cool thanks. does the sp stand for anything?

 

Gracer that was the name I couldn't remember.

 

that is a trust y pipe. u have the same y pipe but different trust cans on my previous fc. pretty rare so keep it for yourself.

 

JASMA = Japan Automotive Sports Muffler Association

Jasma is just the japanese regulations governing exhausts, so means they conform to noise regs etc (i.e they will be restrictive compared to a custom system). They don't make exhaust they just approve..
