I have a 15.5 LML that to make a long story short will soon be running a 5" straight pipe. Now I know for a fact I am not going to like the sound level and drone it's going to have. I didnt get the kit with the muffler since I wasn't satisfied with the mufflers that come with the exhaust kits.

I have read a lot on the FTE resonators.

My question comes in with the different combos you can get them in. My end goal is zero or very, very minimal cab drone, but indo still want a moderate sound level outside the truck. Not crazy loud, but also not stock like quiet. A good middle ground basically.

I see I can get the 17" and 30" in both resonator only and the resonator/muffler combo.

I was thinking the 17" resonator/muffler combo. Does anyone have any input on this? Will it be too loud still or too quiet? Should I go just resonator?

I ran a 5" straight pipe on my truck for a while with the stock turbo and was fine with it. It did have some drone, but it was bearable to me (my fiance not so much). I then put a S300 kit on the truck and the drone was unbearable to me. I still wanted to be able to hear the exhaust, but wanted to eliminate the drone. I decided to run the 17" FTE resonator first that way if i decided to make it quieter i could more easily put the 30" on. The 17" satisfied all my needs. it knocked out prolly a good 80% of the drone i was having with the S300. On a stock turbo i am willing to bet it'll eliminate nearly all the drone. The exhaust note is muffled some, but not too much. If you want to eliminate the drone and still have a "louder' exhaust i would get the 17". The 30" IMO is for someone that wants it to sound close to stock as possible. I would not bother getting a muffler with the resonator. Just run the 17" by itself and you'll be fine.

My 2016 lml is pretty quiet with just a Flo Pro twister with 5” pipe.

Just to update the thread. I put my exhaust on today. Went really smooth.

Definitely dont think I need the 30". It really isnt that loud at all. When you get on it, it definitely screams but normal driving isnt bad.

As expected there is a pretty bad drone around 1600 rpm. So I'll be ordering up a 17" resonator.
