Custom exhausts

[cb1965]

Anyone ever had any success with having a custom exhausts made for their AMG or is it like the VTEC Hondas and you are best sticking to the OEM parts.

Not looking for a cheap job, quite the opposite, but sometimes you can get a lot more exhaust for your buck and in full stainless.

Is yours causing a restriction?
Have you actually measured to see?

 

[Alps]

all depends what you are trying to achieve, the AMG exhausts are designed well, apart from noise which is very quiet on the 55`s, removal of secondary cats and middle box can help, or just replace the back boxes

If you want a full custom mandrel bent exhaust you will be looking at anything from 3k upwards. Remember that getting the right diameter tubing and good quality tubing can increase the cost dramitically, you need to be specific in what you are trying to achieve. Have a look at Chris Tullet Exhausts I have heard lots of good things about them.

hi

we do them all the time it all depends on how far you want to go with it, we did our first full custom system for the 55k about 5 years ago. Also there are many different headers that you can go for.

thanks

Thanks for the replies. Mine is OK right now, but when it comes to replacement time I was just podering over what route to go. I would like a little bit more noise, but don't want it to sound like a boy racer car. I guess it;s the quality of (some) custom exhausts that attracts me.

Acid, when you say it depends how far you want to go what do you mean exactly?

I know these probably seem like simple questions, but I come from a Jap car background and Jags so not too familair with Mercedes and AMG as yet.

I don't know as it's OEM right now, but as above just wondering what the options might be when it needs replacing. Are there gains to be had and if so are they significant?

As above if you are simply after a bit more noise then removing the centre muffler ('resonator') and optionally the secondary cats will do the trick. Many here have done those mods.

Remember that any exhaust changes should be declared for insurance, and having a 'modified' car makes it a little more difficult when you're shopping around for renewal quotes (because some insurers will not provide cover).

As Bill says, be aware of insurance implications.

However, the implications will vary from one company to the next.

I had my silencer and rear cats removed and it didn't make any difference to my premium when I declared the work.

 

[cb1965]

Yeah cheers, but I'm well aware of the insurance implications of modifying... having been into the Subaru scene for years I don't think I have ever had a standard policy in the last decade

Oh my insurance again
Be carefull in case of claim insurers will inspect deeply underchasis to se that resonator is removed,will take it up the ramp,etc :-0

If you are involved in a big claim they will send an experienced engineer who will go over the car with a fine toothcomb. My father-in-law ran a large team of motor engineers who were employed to do exactly this for one of the major UK insurance companies. Think again if you reckon they wouldn't spot large components removed from the exhaust system

 

[Borys]

I know
My point was why to bring insurance issue to an interesting thread....again
Thanx for info....again

 

[cb1965]

Borys, I gather there is some history there LOL! However I do think it was a good point to make on a thread such as this as many people don't realise the insurance implications of modifying cars.

 

[artyman]

What if someone buys a car secondhand, has no mechanical knowledge and wouldn't recognize a resonator if it bit him and is completely unaware that the car is "modified" how does that place him with regard to insurance. I suspect there may be hundreds of motorists in that position.

Even more so with chipped cars as there's nothing visible for that at all.

AFAIK you are OK if the mod. is one that a lay person couldn't reasonably be expected to notice. With exhausts it depends how loud it is, I guess But that argument certainly won't work if you are the first owner
