Adjustable Exhaust Silencer Baffle

Regular price £31.99

Tax included. Shipping calculated at checkout.

As reviewed in Max power and Fast Car magazines! This baffle simply fits into your large bore exhaust tailpipe and allows you to quickly and easily adjust the volume of exhaust by up to 50-75%.  These db killers were originally designed for low powered cars fitted with large bore exhausts and as a result we cannot recommend them for high performance cars.

Perfect for:

  • MOT exhaust volume checks
  • Motorway driving (no more drone!)
  • Track days
  • Reduction in antisocial noise (perfect for residential areas)

To be heard, seen or to get the most out of your big bore exhaust simply adjust the silencer back to being fully open!

These silencers REALLY work! See all our positive feedback on eBay!

Comes with full fitting instructions and free fitting tool.

Adjustable baffle

Does it work? I have recently fitted a stainless 3 inch sports exhaust to my wife’s mini, resulting in a noisy car and noisier complaining wife! I saw this adjustable baffle and thought I might as well give it a go. Well, when it arrived I thought I had bought an expensive 3 inch washer. But being an optimist I gave it a go. It needed a bit of work with the grinder to ensure it would fit, I then copper greased all of the locking pins, tapped it into position and tightened it up.
It was then time to fire it up! I was expecting the usual roar out of the exhaust, but to my surprise it is now more like a pussy cat. Moving on to the test drive, no more drone at motorway speed, it is just slightly noisier than the stock exhaust.
The result of this is an acceptable noise from the car and the wife!
