I really need to try to retrofit my current exhaust with anti-drone chambers...

 

Not true, I have a 3" catless protomotive system on my car and there is not one single hint of Drone anywhere. I dreamt about such a thing and I found it. I busted Tod ***** and several other exhaust makers too about giving me a money back guarantee on my satisfaction and he was the only one that would put his money where his product was. The sound of my Protomotive exhaust is dreamy, 99% of other turbo exhaust I have heard sound less pleasing yet drone.


Now Todds exhaust does not look anywhere near as nice as Chris's. Chris was not making his system when I bought mine.


I myself would not do Inconel. The nice thing about the heavier / thicker stainless is it keeps more of the sound the exhaust makes inside the pipes and directed out the back for a quieter in car experience.


My 3" system throws a lot of noise out the back, when I park in my wifes apartments underground stall and start the car in the morning the place just booms with echos, people walking inside usually plug their ears and scowl at me!

 

The want is strong! I love my UW exhaust! To have it out of Inconel would be nutty.

I had my exhaust shipped to my Porsche dealer when I was out of the country for a few months before I did my install and when I came back they literally did have it hanging on the wall in the showroom. Chris is the man!

 

Pwdrhound, does you SS UW exhaust have "anti-dronez" (as they call them) AKA 1/4 wave resonators? And could you comment about how loud they are in regular driving

UW SS with "anti dronez" were first choice by a long shot but decided to go the Kline route for less noise (keep the lady and baby happy) and more refined sound. Well that, and Sambo@ByDesign worked out a phenomenal deal for me.

 

Yes, all of the UW exhaust have the 1/4 wave resonators. This is my SS below with HJS 5" 100cell race cats and small straight flow through mufflers prior to the tips. The wavy pipes are the resonators. The exhaust is very pleasant and quiet inside, actually easier on the ears than my RUF exhaust which was basically an OEM exhaust with 100 cell race cats. The UW exhaust certainly has less drone than the RUF, actually none. Even a stock exhaust has a very slight hint of drone in my opinion. On the outside the UW is relatively loud from what I understand but not in the car.

Inside is quiet, outside..... not so much No mufflers, mine does have cats however. You can listen to the stereo inside pretty easily IMO.

 

Just received the exhaust and as usual the craftsmanship is phenomenal. Due to several other higher priority high $$ projects, I've decided to stick with my SS Unobtainium for now and as such I'm offering the Inconel/Ti for sale. It is brand new and still packed up in the box. Here is a chance for someone to grab one of these at a substantial discount and without the 6+ month wait to get one constructed.

keep it and sell the s/s unit!!!!

 

When you run catless on these cars, best to use a spacer or something to avoid an error code?
