V6 engine. Has anyone pulled the cat and taken their car offroad to test it? Was there much gain at 2k & 3k rpm or just up near 3.5 to redline? Did it help with torque? Although I am not sure it would because the torque, I think, is more internal to the engine. I could easily_be_wrong_on_this_assumption. TIA Vince v431@ultranet.com
