ISF Axle Back Exhaust Options

[Arqum]

Hi All, 

So I'm after upgrading my factory axle back exhaust. I want something that won't give me drone. Switchable is an option. Any advice please?

There are very few axle back exhausts on the market for the ISF available in the UK.

There is a group buy for a Hayward & Scott cat back in this thread which is known for having very little drone (and sounding lovely)

Some people have fitting a valve and switch themseleves (via a local exhaust shop) to the exhaust before the back boxes which is very loud when open and like stock when closed.

I have read mixed reviews Re the H&S, some say drone, some say none.

Even the stock exhaust drones slightly.

A louder exhaust is just that, you can't get more of the noise without getting more of the noise 😈

Bang on the money. It's inherent in the stock system.

@Arqum, like you, I hate drone. So, you're either going have to go switchable or just don't bother.
