With catless dp right?

I ran a catless dp on a previous car but since then I decided I won't do it again due to the terrible smell and for emissions reasons. I'm really liking that an S58 doesn't really "need" a dp to come to life. In the future I'll definitely consider a flash tune or piggyback with a couple of bolt-ons.
Yes catless;No it doesn't need it at all. I've heard the smell is only during start up in the morning. Some of the guys said it's not bad at all.. but it's really preference. Jb4 on a good map 4 gallons of E85 and a midpipe you can hit 10.5's all day.
I used to run my N54 on E30 with stock cats. I never had any problem. I know people who have ran their N55's on stock cats with ethanol as well.
