Exhaust
#27
If it is secondary cat, would the car still meet all the ARB requirements (specifically in California)? Also, do you smell more fuel while running without these?
I am very interested in getting this done since you guys (contrary to the shop I went to) have mentioned its an octave lower.

Thank you, as I suspected previous members falsely claimed they were resonators and not cats but I had a sneaking suspicion they were cars (hence sebring).
so you should pick up more power and sound from the second cats removal. Seems like a cost effective was of getting more flow & sound without getting downpipes. Keeping primary cats actually makes the car sound better IMO. Full cat less downpipes don't actually sound that good and cost a fortune and are a pain to install. This seems like a much better route with the X-pipe in addition
Now do X-pipe in place of the two H-pipes and it will be perfect![Smilie](https://mbworld.org/forums/images/smilies/smile.gif)

To me it’s perfect now.
Plus, I’ve said this before, When I removed mine originally they were on the garage floor for 45 minutes and I went to pick them up and put them in a box so I could leave and I burned my hands. I couldn’t believe the amount of heat that was still in those cans almost an hour later

Catalytic converters run extremely hot! lol
I would be interested to know if an owner in a state like CA has had any issues passing emissions testing with the secondary cats removed, along with whether it creates a ‘black flag’ condition at certain road courses that are OCD re: noise levels.
