1) Do you replace front two and delete the rears without any codes or issues?
2) Is it noticably louder to someone hearing it for the first time after installed that wasn't aware you switched them or is it louder because you want it to be? lol
3) Is it louder inside, outside, or both and at idle?
4) Did you notice any performance change?
Thanks for any questions answered. I just want to know before I dish out the dough.

 

good questions. I want to know the same. lazy sub.

 

1, yes.

2, yes.

3, louder in every way.

4, Theres a very minimal gain because two hi-flow cats is less restrictive than 4 OEM stuffed up cats.

 

Thanks Darren for your help.
