Question about catless to catted fp with OFT
 

Running full exhaust uel,op,catless fp and n1 catback, with stage 2 tune on OFT,I'm swapping just my fp out for a catted one (due to being tired of the smell,plus the wife hates it too,lol). My question is will I need to reflash the tune or do anything on the OFT or will "recalibrate" for any changes it may make? Just wanted to be sure beforehand. Thanks in advance!

nope

anything changes after catless header is ok

Sweet, thanks man!

Which catted FP are you going to use?

I'm curious to see your results with smell and loudness.

Berk,will be installing this weekend so I'll see then. Have the Motiv test pipe now,fwiw

I briefly ran catless with my UEL and test pipe. Didn't mind the sound, but the smell in the garage got to me. I put the stock FP back on and have had it that way ever since. Though I always wondered if a high flow front pipe would have taken care of the smell and not effected the sound...?
