First of all, I want to said hi and thank you to all the experts that going to help me decide on which upgrade. I own a 2014 911TTS with 14K miles on it, warranty will run out April 2018 and I'm looking to do some mild upgrade to an already impressive car. So I do have a couple questions:

The Boost Logic Formula Series Titanium Exhaust for 911TTS I'm about to buy is a cat-less system.

1. I want to know if anyone in this community have run cat-less system and how are they sounds during regular drive? is it bearable, any drone? can you hold a normal conversation during freeway speed with the system driving in normal mode?

2. How are the smell generated by these cat-less system? can you smell it while standing still & idle, while driving in the city, and how do we pass smog etc?

3. I planning to get a tune with it, there is two I'm considering FVD $1600 and COBB for $2200. Is there any difference? What RWHP I'm looking to get out of a cat-less system and a tune? lastly, any vendor can offer me, military vet, a killer deal on either one of these tune?

Personal opinions:
1. I have been running cat-less system for few weeks now. It sounds absolutely amazing! Change the character of the car completely. But there is a bit of drone, you can have a conversation in town/freeway. But around 75-80 mph, drone gets bad = turn up the volume. BTW, don't believe any "This catless system has no drone".
2. My car had strong smell when i put shell 91 v power. Recently i switch to Esso's 93, I barely smell anything. I don't have smog here in Ontario, so GL with that. The check engine light is prevented by a J style O2 spacer(Only works with 93).
3. Don't know much about FVD, but COBB is for sure the top of the line.

Get cat-less downpipes and shoot some flame!

I have been running Tubi catless since the fall of 2015. It sounds wonderful. No drone.

What about exhaust smell? and Smog test, how do we get around that?

Nanook

No noticeable exhaust odor at all..no smog test for us CDNs

Of course catless is going to smell. I can't back into my garage unless I want it full of noxious fumes. That will happen with ANY catless exhaust.

Which begs the question, what is your goal with the car and why catless?

Longboarder,

There a forum member selling the boostlogic titanium catless system for a really good price. That is why I'm considering catless. I would much prefer the 200 cell cat.

people usually go catless because their desire is extract max power with a combo also including tune, intercoolers, intake plenums and maybe meth injection and/or upgraded turbos. Otherwise a catted exhaust is usually the better option due to all the negatives from catless.

Also I would listed to a few exhausts before choosing one. Have you heard the boost logic catless exhaust?

Is the boostlogic system cheaper than a good ole Sharkwerks? That might be a better option for the money.
