well i read a couple of threads were guys have taken off the bottom cat and had no problems but i was wondering if anyone has taken off fronts and left the back ones on. any thoughts on this?

 

i just took all of mine off and idk if im better off or now lol i may be getting worse gas milage

 

i just took off the bottem cats and it was super easy and i like the sound now with my flowmaster muffler and just the first cats. it sounds good and i dont think it would be worth the trouble to take off the front ones. and i havent really noticed any difference in gas mileage

 

In theory you should get better gas milage(being more free flowing) I just can't keep my foot out of it.

I took all mine out and it sounds nasty at WOT!

You'll also lose Torque from it not haveing much back pressure, but you don't want back pressure

 

thats what i thought and how much tq do u loose?
