That Db limit is based at the shack on the track. So basically dependent on the distance the reading is taken, throttle position, temp, etc etc. it is hard to say if it will pass or not. It bolts right up to the factory flanges, so bring both with you, if you get flagged, spend 20mins or so if that and change to factory. The bolt locations are easy to access with out needing to jack up the car.

is it possible to get a little discount if I were to pick them up from you instead of shipping?

Can anyone comment on how these compare sound and drone wise to say a full exhaust like
a fast intentions?

Between 3k-3500 and 4k-4500 there is some resonance but at highway speeds there is no drone. I would only get this if its temporary, like a year or 2 then getting a new full exhaust system.


Yer neighbors might not like you if you have a garage btw, on startup its growls like a tiger and then drones and resonates for a minute, almost like a big block v8 lol. :excited:

Heh, If its WOT, I bet its in the 100db range lol ;)

Thanks Initial Z. I leave at 6 in the morning and always warm up in the driveway so ya it might be an issue! :icon17:

You could pick it up but there would be tax :(. Shipping to VA there is no tax.

WOT from about 4 feet measured 105db max...

they sound awesome - no real drone - but definitely a big growl when you press go.

The neighbors will just have to deal with it. It's not like you have a Harley or something! I am up and out by 0530 and my neighbors don't complain, but they haven't heard my 3" non-res TDX yet, lol!

Yeah sound levels are measured at WOT, though the distance changes based on the feeling/location etc.

How's daily driving? I'm more concerned with so cal cops. A bit louder than stock is fine, nothing too obscene.

Daily driving is fine, shifting economically and crusing its pretty normal with a little brrrrrrrrrr. Its only obscene when its above 4k really lol. :icon14:

At cruising you cant here it, but at WOT it is a beast. And yes it sounds like a built v8 when it fires up in the morning. LOL. I love the sound. Different tips then mine, but sure it sounds fairly close.

Adam, could the shorties bolt up to a Nismo S-Tune CBE?

The S-Tune I believe is 3" diameter all the way back to the muffler. Need confirmation on this...

The shorties from the description on your website is "Built from 304 stainless steel, the S-Line Short Tails feature 2.5 inch pipes from the flanges to the 4 inch diameter polished stainless exhaust tips".

Do we know the value of max power and torque with this exhaust ? What is the order of the loss?
