If it’s anything like the A35 then the only resonator after the GPF is the back box itself, and back box deletes are very popular, nice increase in sound without the expensive outlay of a full system. Might be worth checking out PCW exhaust mods, they modify standard exhausts, plenty of videos on YouTube etc. I was quoted £280 for a modified back box on my A35.

 

I think 45 has a front resonator, looks a pretty easy delete

 

I am thinking of doing just a back box delete for now but unsure if this would affect the warranty in any way. I imagine it will only affect the warranty on the exhaust but not on the engine.

Does anyone have any pictures of the underneath of the car? How many resonators the car has or what the piping looks like?

Why don't you take the car to an exhaust shop?
Deleting resonator would definitely make a huge difference. A mate did it on his new CLA45S and it sounds a tad louder, insanely louder pops and bangs in S/S+/R modes. We get AMG exhaust without OPF so that makes difference too, our cars are slightly louder but more refined and subdued compared to outgoing models. Resonator and rear muffler pictures attached.

Technically the A45s without OPF should also be more free breathing and as a result a tad quicker. After the new EU regulations, many manufacturers had to fit in OPF filters in their cars which saw a reduction of max hp.

Maybe good to try a few timed performance runs on yours and see how it stacks up with the owners from the UK?

 

Currently exploring options to make the exhaust louder. On the lookout for any exhausts being released or custom mods people are thinking of.

iPE have released an exhaust which will be ready in 4 weeks. They have quoted £2950 for the exhaust and £500 for shipping and fitting.

They don’t want much for the exhaust that’s big bucks

 

i would sleeve the front resonator and leave in place, dealer would never know unless they cut it open

 

Would it be better to do a muffler delete rather than a resonator delete?

“The main distinction is that a muffler is designed to muffle the overall volume across all RPMs, whereas a resonator is designed to eliminate unwanted resonance or noise at a particular RPM, also known as exhaust drone.”

 

My Ecu is going to Dms start of the week to get there map in it supposed to be 480-490 bhp
and getting Dms to turn off the opf filter etc was thinking off cutting out the opf and cat and resonator am I mad? How does this work with warranty ? could I bust out the opf without them knowing ? whats your views

 

Ok wait so there's four components that affect the exhaust sound? The cat, OPF, muffler and resonator?

Lol I reckon they will know if the OPF has come out. Warranty is a grey area ... is the OPF after the engine? If so physically removing it can't really affect the warranty of the engine (which is the important part). Any exhaust mods I've heard only affect the warranty of the exhaust but not the car or engine. But if they find out you messed with the ECU then that'll void the warranty on the engine I reckon.

 

Regarding the warranty i think there are at least 4 reasons in your list that they might take issue with 😂😂

 

Removing the GPF/OPF will void the warranty on the engine, as the ECU will have to be tuned to suit. Carwow did a comparison of an RS3 with and without the GPF and it made zero difference to the performance. If you value your warranty it’s not worth the risk in my opinion.

 

Lol we all terrible in a good way................, All of us have serious quick cars and yet looking for more................................Legally of course

 

😂😂😂😂

 

Sorry to hear that forester how much u paying for the new tyre ? Pm me and might be able to help u get it cheaper

 

Lol I have a feeling someone with an a45s is going to wake up with 3 tyres on their car 😂

 

Ok so I picked up my car yesterday. It sounds amazing ... its definitely louder. The sound is similar but louder and slightly deeper which is what I was looking for. I’ll add some pics and videos of the exhaust and sound later.

One issue. The garage were a bit baffled - it was the first time they had seen it. There was a pressure sensor at the rear of the exhaust. They have no idea what its for but they added it to the new exhaust anyway. And in idle, when you start the car and switch the exhaust on, the valve opens but when you press your foot against the accelerator, it shuts the valve straight away. They messed around with it and tested different things and concluded its coded into the car. Maybe this has something to do with the pressure sensor?

Weird thing is, in the iPE video for the a45s exhaust, they manage to keep the valve open when revving in idle ...

Also if you look carefully, it looks like they have a decat downpipe in the vid. I thought they had only released a catback exhaust??

Anyway ... thoughts?

@veeeight

 

Nope they do a down pipe & front pipe OPF catless but it’s big money
Have you your car mapped yet ?
Any more pops and bangs

 

How do i add videos lol

 

Insert media. It appears in a drop down after the emoji by clicking the dotted lines.

 

Videos of new exhaust:



Video of old exhaust:




Thanks @Forrester

 

Any chance you can tell me the brand and model of the muffler they used in your new exhaust?

 

Not got the car mapped and wasn’t planning to anytime soon. And yes deffo more pops and bangs especially on the downshifts. Is there anyway i can code out that annoying valve thing when revving on idle?

 

Dms could sort but means the going into your ecu

 

Some vids of sound

 

Is that a cat-back system? Our standard AMG Exhaust is louder than this!

 

Spoke to DMS who advised that the sensor was an air pressure sensor to make sure the OPF is working. They think the valve closing when revving at idle is a fault ...

Can someone check on their oem exhaust whether this is the case. I’ve got a better video of the valve closing when revving at idle. You can hear the valve open again after i let go of the accelerator.

 

The valves close when revving on idle due to the EU regs on noise. They stay open when driving.

 

Could dms not sort this and keep it open when mapping did they say ?
Sounding good nice to hear a few bangs when revving when idle

 

They said they can look into it and should be able to do something in the map. But I’m not sure on doing a remap so soon. After driving around i’ve realised the oem exhaust was so **** lol ... it shouldn’t come so quiet from factory.

 

Nobody still hasn’t frontdown pipe available in the Uk ready yet for sale
has anybody any feedback ?

 

I swear irish boy is going to be welding his own down pipe soon at this rate 😂

 

Looking through many threads is there an option at all to keep warranty and improve exhaust sound? Do amg have a modifier that’s approved?

 

What I did to my exhaust does not affect my warranty. It would only void the warranty on my exhaust, not the engine which is the important part of the warranty. You don’t really need a warranty on exhaust it’s just a piece of pipe.

 

You would have been a great fella if you would have got a downpipe made and a couple spare when your car was in
Milltek are mid August end to get there new OPF delete and super sprint are by order only which is 5-6weeks when placing order
Ipe can send straight away buts is costing $1300 plus import duty etc

anybody been in touch with company in Poland TG motorsport who-make the three own exhaust ?

No but have you tried our friend on the gen one A45 part of the forum.
