converters

[redrocker]

i just picked up a 90 gt , its a 56k mile car and all stock . it has 4 converters on it . can i take them off without any trouble ? will it mess up my gas mileage or my computer ? what the difference between a h and x pipe ? which is better ?

Ive got a '94 GT with a Mac H, stock headers and flowmaster's with dumps, and its got a more picky computer than your '90 and it loves the fact that it has no cats/resonators... and i think i actually picked up a few miles to the gallon since the exhaust is more free-flowing but thats only when i can keep my foot out of it:D

h-pipe supposedly gives you better low end tourque and a deeper tone

x-pipe supposedly gives you higher horsepower and a higher pitch tone

as to which is better i do not know, i havent had both, im sure someone will chime in on that one...

It'll run fine w/o the convertors.

Just reset the PCM (by disconnecting the battery) and you'll be fine.

what the difference between a h and x pipe ? which is better ?(6) of one... 1/2 dozen of the other unless your splitting hairs. Change in exhaust tone is the biggest difference.
