yeah, another question about cats

[LT1 > LS1]

so, I am thinkin of either ditchin, hollowing, or changing my cat.


if I change it to like a high flow magnaflow, will volume increase?

if I hollow it, will it throw codes?

if I put in a straight pipe, what do I need to not throw any codes?

[Mr. Luos]

If you change the cats at all...it will throw codes.

The rear O2 codes will need to be turned off via HPTuners, LS1Edit, etc...

[LT1 > LS1]

I have an LT1 car......


so how do I go about clearing, or modifying the codes? if I dont fix the codes, will it make my car run different. like will it richen it up or somthin?

[Mr. Luos]

If it is like the LS1 cars, it won't change anything.
