Hey everyone. Sorry if there are already a million posts about this.
So my CEL came on 1 day after buying my car. It gave a P0420, saying something about banks are too lean and the cat should be replaced.
So I was just going to get a cattless downpipe with an 02 spacer for no CEL.
I was wondering if anyone have experience with this?
The main question would be if it will sound nice with a stock catback exhaust.
I am planning on getting a catback at sometime, but right now im just replacing the downpipe.
My last car was a 1998 mustang gt with a cattless midpipe and flowmaster exhaust, i do not want something this loud again
Any advice? Thanks
