Napa 6637 question
So looking to add the 6637 filter kit from riffraff. How ever I am wondering if it would be best to replace the stock tubing with aftermarket 4" and then the filter, or just leave stock tubing. will I gain anything from adding the 4"? Also do you gain any sound from going to the 6637 filter? And will a 4" also add sound
About me I am very new to the diesel world. Had a 88 ford about 6 years ago and that was it until now. Which I have a 100% stock 2002 Ford F250 Crew Cab Lariat 7.3. I only got the truck for towing our bass boat and my run around rig. Love it so far but do plan on a few small upgrades ie intake, exhaust and maybe a tuner.
Thanks for any help

So second question is sound. I want to hear the turbo. Will just the filter add do that or will a full aftermarket tube do that?
Thanks for you help

The Donaldson 085046 is the marine grade version of a 6637. It doesn't matter if this one gets wet so I feel that it would be a better choice for an open element filter. Been running one in my truck for a few years and been happy with it so far. Either one would be better than the factory filter.

So the exhaust is actually where you hear the turbo spool from? That makes sense.
Thanks guys

You actually hear the turbo whistle from the intake, the exhaust just improves flow therfore allowing it to whistle more
