I love my Chimaera and it would be great if I could use it everyday. Unfortunately, I work unsociable hours and can leave for work as early as 03.30 and get home any time up to 02.00.

I’d love to use the car as my daily but I fear that I’d annoy a lot of my neighbours if I fired up the TVR at those hours. I see that lots of new cars have exhaust valves that open up to vary the volume, is this an option for our cars?

You could try using some track day cans, the type that insert into the tail pipes as opposed to slip over the tail pipe. These are less obtrusive but certainly quiet it down. I have a pair in my garage if you want to try them.

Thanks, that’s a very generous offer and I think that I should take you up on it.

As far as I’m aware I have a standard exhaust fitted so it’s not massively loud as it stands but taking it down a notch would be welcome for those early starts.

Adding a turbocharger takes about 12 decibels off the noise levels. silly
I got accused of entering the hybrid/electric vehicle class on the last sprint day i did.
My car, fully decatted, is now 90 dB(a). Standard Chimaera with the cats in is around 96dB(a).
It was about 102 dB(a) on a good day before the turbo.

Oh, and it adds about 80-150 bhp too.

That’s an appealing if extreme solution!

Had these made a while back. The external diameter was increased so the internal baffle remains the same as the original tailpipes. Brings it down to 92db perfect for track days and touring holidays.

Great solution. I drove it briefly and it really works a treat.

Hi,

I just recently installed these within my tail pipes.

https://www.denniskirk.com/drag-specialties/baffle...

They were super cheap and slid right in. For now I'm using the fixing screw with a washer at the tail pipe opening to just hold them in place. Once I'm convinced they are the right option, I will drill a hole in the tail pipe and place them deeper.

They are almost too quiet. Just a very subtle rumble.

I'm debating whether or not they may be too restrictive. The engine seems to be running a bit hotter. I may change the "padding" to a looser fitting material and I may also drill some holes to increase flow a bit.

In the meantime I'm enjoying the sophisticated sound vs. the beasty rumble/roar.
