since i bought my 89 supra the fumes coming out of the exhaust system were unbearable. I bought it with a 3 inch cat-less exhaust pipe from the turbo straight to the dynomax muffler. So last weekend i bought a magnaflow 54959 universal cat 3" in/out spun to 4" in the middle. The supra sounds alot better (low tone) however i feel its alot more sluggish than before. Will a highflow cat bring back my performance(or close).... or is it all in my head.
supra runs alot sluggier with the installation of a cat

im gonna guess most of it is in your head... on my 85 (i know not an mk3) i replaced an old worn cat with a 3 inch straight through glasspack and didnt notice much of a performance difference.
but i guess with a turbo motor it could be different....
ill probably run catless when i finish my 2.8 turbo 5mge

Might try the turbo section for your car...
Anyway, I run catless, and have no problems at all with fumes. I would suggest checking for codes, maybe a tune-up, and some diagnostic work to see why you're running rich.

QFT. Btw Hommer, you're right on the money. Any restriction in the exhaust will reduce power.
