4 or 5" rehash

Ok, I've read a few months of threads.... to try to figure an answer...still not sure.

4 or 5" "close" to the same price, may as well get the 5?" or would that cause problems for some reason.

I only have an air raid intake and a totally freakin sweet SCT looney tune. (I can spin 35" tires...thats insane...I digress). The only other mod I would do is not performance related.

I think I want to keep the cat, for sure want a muffler.

Last thing I want is major resonating in the cab as I do several long haul trips/year.

I dunno which to get...06 F350, lifted pretty high. Help!

Probably going with farmboys

i would go 4" if your going to keep the cat... because i dont know of anyone that makes a 5" cat so your DP is gonna go from a 3.5" flared out to 5" then back down to the stock cat size then flare out after the cat.... stay with 4" and you will be happy.... or go straight piped.. thats just my opinion

go 4 and get rid of the cat and muffler!!! it isnt really noisy going down the road unless your rev it high all the time! but it sounds awesome!
