Exhaust note adjustment

Ant132 · Post by **Ant132** » Thu Nov 27, 2014 11:37 pm

Hi folks,

Just bought myself a little MGF, looking forward to being part of the crew.

The exhaust on mine is a new system but it stupidly loud!! Unbearable.

I'm told that there is a control in the engine bay somewhere that can silence the noise a bit, anyone familiar with such systems?

Alternatively, any other ways I can save my hearing?

Welcome to the forum.
Unfortunately whoever gave you that info was a little misinformed.
On some MG TF's (typically 2002-2004) there was a small vacuum operated valve in one tailpipe that lowered the exhaust volume by a very small amount at low revs.
The valve isn't found on earlier cars such as your F, so I'm afraid the only real option you have it to change the silencer for a quieter model.

Swap it for my old standard box if you want

Thanks chaps.

I would, with pleasure! The system is almost new, you would be welcome to it - be advised though it is seriously loud!

Is yours in good useable condition?

Still on the car at the moment and went through the mot this summer.
I haven't been under the car since but will try to get some photos if you like.

Yes please - i'll try and get you a Db reading for mine. Apparantly it cost £400 so must be decent, i just cant bare the noise - i'm wearing ear plugs for driving at the moment!

There are those who would pay with their right arm for a really loud exhaust. Find what you have fitted, sell it and fit a new original.

My thoughts exactly, as much as I would love to have a loud exhaust I don't want to see another MG owner out of pocket.

Not sure if mine is oem but not too loud so probably what you should shop around for.

Also had a thought, do you have a cat fitted?

I picked up a new Bosal rear box for my 97 MGF for £70 delivered a few months ago from:-

www.ClickCarParts.co.uk.

It's a louder that the original box but not LOUD.................... loud. Sounds a bit more like the old MGB's did when one is driving it. I have seen the same Bosal boxes listed at £100 more...................... just goes to show the mark up some work too!

Im not sure what type it is, here is a pic, i can vaguely see the word POWER on the left tip, but no real other indicators.

How can i tell if theres a cat fitted?

Choices there are probably:-

X-Power or Powerflow.

Hi and welcome to the forum Ant

That script looks like the one used for "X-POWER", the MG tuning brand although I thought supplies of the MGF pipes had dried up.

If I were you I'd buy a cheap replacement and sell this one, possibly on ebay where the market will decide it's value.

If you look under the car between the silencer and the engine there should be another smaller "silencer" which is actually the cat, if there isn't one it will be adding greatly to the volume of the exhaust sound.

When getting a replacement make sure you get one for your model - i.e. mk1 F or mk2 F/MGTF.

Powerflow script is like this

and usually embossed on the silencer.

Thank you!

I'll have a good look underneath - if theres no cat, what is the gap filled with? Or is it just easy to omit.
