looking to get exhaust. witch do u guys think is the best dpf safe exhaust?

 

With all of the aftermarket systems, you risk turning the check engine lamp on for DPF efficiency.

Ford says don't modify the exhaust at all.

If you're gonna lose the DPF and CAT, then any good 4-5" catback will do. I plan on using something similar to the 5" Magnaflow cat back on my truck when I get things sorted out financially
