E55 AMG Exhaust

[Kieron]

Hi all,

The cats have gone on my E55 and I was wondering what options I have with regards to a sports exhaust? Can anyone reccomend a decent system at all? i would like to get the best out of the V8 and have a nice purr at the same time as the standard pipes are very quiet.

Its an S plate BTW.

Thanks

Replace your cats with genuine MB ones, as you will need these for the MOT.
Then, remove the centre box for a deeper growl.
You can even go as far as I did and have the guts removed from the rear box and have a 'V' plate put in in their place.

Worth doing a few searches on this as it's a fairly common topic.

There are plenty of companies that will make up systems for you ... typically this would be from the cats back, but as you need cats you could possibly get free-flow cats included.

Look for Hayward and Scott, Longlife, etc.

Obviously anything other than a standard OEM exhaust must be declared to your insurer, and may affect your premium and/or excess (depending on the company).

Many people find the standard exhausts too quiet. I had the centre box removed from mine (replaced with straight-through pipe), which is about right IMO. Still virtually silent when cruising, but you can hear a bit more when accelerating.

I was at long life exhausts about a month ago getting the centre box removed, and they said they could build a custom exhaust system.
They also do cats as well though not MB ones.

Not sure about the life span of Non MB cats and whether they would pass an MOT test.

I called Mercedes about the cats and they are £1722 + VAT Ea. So thats £4046.70 for two cats, hence this post!

Thanks for the info on the centre boxes being removed.

Anyone got any details on longlife please?

I know they are silly prices!!!

Do a google search for Longlife.
Not sure where you are based but they are all over the UK.
The number on the website can give you the closest branch.

Yup what e55 said. I used the Croydon branch of Longlife, first to fit the AMG back box and then again to remove the centre muffler. Both done in about 90 mins IIRC.

On to them now thanks.

Since when has replacing a failed part with a none-OE one become a material fact for your insurance?

This thread is about fitting a "sports exhaust", which is definitely a material fact as far as insurance goes.

 

[GrahamC230K]

Given the cost of the replacement cats alone from MB, I would get a COMPLETE system made up to allow a bit more flow, noise to suit your taste and some sports cats with a lower CPI.

 

[Kieron]

Long life will do me a full stainless system with cats and centre box removed for £699. Or I can get sports cats added which are £350 ea.

Thanks for all your help guys

When u get the centre box removed (my understanding that is actually the front cat), will it even pass an emissions test on an MOT? or is the idea to put it back just before an MOT, then switch when done?

Also if u got stopped, wouldn't u get your pants pulled down by the cops?

No, the centre box is just a muffler. And the difference in sound without it is pretty subtle, still far quieter than any stock TVR or say an SLK55.

This thread is also about an AMG car - I doubt that fitting a new exhaust from a different supplier than MB is going to improve the performance, or even be the intention. It's likely to be a cheaper part as well (unless it's a Brabus one) and therefore not fall foul of the insurance in time of claim.

The standard exhaust on the E55 is reasonably restrictive, so I would expect a slight performance gain from any sports system. That's immaterial though - anything other than an OEM or pattern exhaust should definitely be declared to your insurers, regardless of how much it costs or your reasons for fitting it.

You do realise that even purely cosmetic changes must be declared?

Define pattern? Surely anything other than OEM by your definition would be a modification.

Anything that is a material fact that non-disclosure would induce the underwriting of a policy must be declared, other than that you'll find things are a little more vague.

Where would you start with many of our MBs? CD changer (not standard on most cars)? Premium Audio? Comand? Folding mirrors? Electrochromic mirror glass? Even adding a rain sensor increases the cost of a replacement screen.

If the argument came up that the aftermarket exhaust, be it made by Bosal or Brabus was undeclared at the time of policy issue the worst that should happen is that the insurer will pay to the price of an original part, unless it can be shown that the part contributed to the cause of the loss, and therefore we have inducement, negligent non-disclosure etc.

Did you read the links I posted above? E.g.

What do Insurance Companies class as a Modification?

99% of insurance companies will class any modification to a car after it has been manufactured as a modification. It is worth nothing that some insurance companies will class factory fitted extras as modifications.

Typically when applying for cover you are asked if the car has any modifications. Failing to declare may mean you are not paying the correct premium for the RISK, hence the insurance company may void the policy.

Please feel free to check with various insurers whether a custom-made s/s exhaust system with sports cats should be declared, and let us know what they say.
