Hi
I decided to fit a Remus CAT back exhaust system to my 340 V6 F-Type. When I was looking into different systems I found it difficult to find any detailed information regarding noise levels / loudness etc. The best information I got was from other like minded forum members, so thanks to you all.
So with this in mind I decided to carry out a totally unscientific experiment for my own curiosity and maybe too inform others.
Please keep in mind that I am not a sound expert but just someone with a decibel meter purchased from amazon.
This is just a bit of fun.
I have attached the following readings that I have taken before and after.
Method
Purchased a cheap sound meter from amazon “Sound Level Meter, Tacklife MLM02 Sound Level Meter, Measuring Range 30-130 dBA,”
I took three readings for each test and what is shown is the average of these.
Used the same conditions and location for before and after readings
Start up readings (warm engine) taken behind the car 1.5m from exhaust tips
Stationary rev test to approx. 5k revs, basically blipping the accelerator to full
The above rev test overwhelmed the meter at anything less than 8m distance so this was used as a control point.
In cabin readings taken between seats at head level under normal cruising conditions
0-60 cabin reading was maximum acceleration using same method
Car windows up and audio off.
Active exhaust means Dynamic mod with active exhaust engaged
Normal “D” not sport “S”
Conclusion
I am only a few days in to this but my initial conclusion is “ Glad I had it done”
If I had to describe the result I would say, “the Remus on normal mode is similar or maybe a little less than the OEM exhaust in dynamic. However, with the active exhaust on with the Remus exhaust it’s a whole new ball game”.
Other observations
The tic over burble whilst not significantly louder has a much deeper tone.
The build quality is very good
Took just under two hours to install (authorised Remus supplier and fitter)
Kit is complete with all clips mounts and extensions to vacuum pipes
Tail pipes I chose were chrome option but are easily interchangeable
There is a supplier YouTube clip of the exhaust system in action, but doesn’t really do it justice.

Note
It should be noted that the decibel scale is not linear, for example 100db is about 8 times as loud as 70 dB.

I notified my insurer of the modification and it attracted no additional premium
Hope you find this of interest and useful. Again, I must point out that my readings may contain errors and are only my tool shed experiment and do not reflect any actual Remus or Jaguar factory information
