Ok what i ment to say was i have a remus exhast.
Theres a magnaflow high flow catylik
i have terrible backpressure.
my fuel is running rich...

jturkel

by terrible backpressure, are you saying you have no backpressure?

so you have a remus muffler, and magnaflow high flow primary catalytic converter....

what size muffler? and what is the cell count on the the cat?

for the record, exhaust mods without a tune can definitely result in you running rich. for example, since i'e been my headers on, my car has run more rich. i need to get it retuned to resolve that. and it is definitely better to run rich than run lean.

have you considered getting a tune to resolve this problem?

also, have you lost power (especially down low) with the lack of backpressure?

sometimes, bigger isn't always better because of the importance of backpressure on exhausts on naturally aspirated cars
