On my 86 GXL, I have free exhaust all the way from headers, y's and rear pipes, no cats, no muffles, and if i shif after about 7.5 k, it shoot flames, it this bad for my car, what causes it?

Flames are natural for a rotary since they're very fuel inefficient and lots of unburned gases make it to the tailpipes!

FLAME ON !!!

NO MUFLERS!!! it must be incredibly loud.

suuuuuuuuuper loud, but i loveit, its a sound like no other, and since im in florida, screw emissions. When I went to buy the pipes for my straight exhaust, i had it as an open exhaust, and it sounded badder then some tricked out 350. All the big block guys were grinning and smiling, but then i flamed out of the bottom of the car, that was scary, i only had headers on the car. ts a definite head turner. Thanks guys!

mind if i post a question in here?

would an safc used to lean out the fuel amount lower the flamage? i know that NA's dont need to run as rich as they do.

hmm...........good point, and would any gains be seen with an safc.

to much flame could be a sighn of running to rich (fuel) my 87t2 does not even flame at all and i have full exaust system no cats. if i bring it up to 7k rpm and let off it does not even flame WTF?
