Hey guys I am about to remove the CAT from my navara next week.. I am going to unbolt it from turbo back to DPF and get a 3" pipe made up for it as I already have 3" from DPF back... I would like your opinions about doing this.. the real reason for this is to see if I can get a note out of the exaust as you D40 owners know that there quiet asssssss.... im also doing it to improve flow rate and power gains Thanks for taking your time to read this and hopefully answers!
