getting ready to redo my exhaust system. headers back and was wondering what the pros and cons are with losing my cats. i got some ceramic coated pacesetters waiting to go on but don’t know about keeping the cats. i plan on getting cut outs before some high flow cats then some areochambers or sdt mufflers with 2.5in all the way back. or should i just do a cat delete

 

Do away with um useless IMO

 

Lose the cats. You will need to have your rear o2 sensors deleted. If your not tuned this is a good time to start thinking about it. The only con IMO to not running cats is smelling like gas all the time

 

Agree^^^^

 

thanks guys i think ill be getting rid of the cats. which muffler though? i like the areochamber and the std so its between the two. (dont like cackle)so need a chambered muffler, im thinking 2.5'' dual all the way out with an h pipe, cut outs and mufflers.. any Opinions?

 

im wanting to keep some back pressure to so I don’t lose all my bottom end

 

Love the sound of no cats.

 

I agree completely. Lose the cats, and as far as mufflers, gotta go with MAC Performance. They have the same traditional Flowmaster 40 Series sound, but with a little more bite. They sound really good if you're cammed, and better if they're dumped!

 

im more of a dog person

What you want is exhaust velocity, not backpressure.
