Iím debating deleting my Secondary Cats...
 
But I donít want drone and I want more bark and a bit more volume. Iíve read all the threads and Iím almost ready. Whatís holding me back is not being able to hear any sound clips. Does anyone have any clips they can share or post? Thanks for your help!

AMG 17GT 03-14-2019 01:08 PM

All the threads tell you what specifically? And what do they say about vids?

DriveAMG 03-14-2019 01:39 PM

What is it you want to say?

Iíve made a specific request for a sound clip as I am unable to find any. Cheers

AMG 17GT 03-14-2019 01:50 PM

Ok well I say this because every thread says same thing.....that vids and recordings don’t capture true depth of sound.

This is is the easiest way to get more of the same an octave lower as I’ve said before. There is no drone as every thread has confirmed

DriveAMG 03-14-2019 02:20 PM

Alright then.
 
Thank you!. Lastly anyone done this in the TORONTO area that I can meet up with in person?

Deeper sound. No drone.

Orcbolg 03-14-2019 05:43 PM

Do it! Seriously, 0 drone, much better sound. The best part is, in Comfort, it's still very quiet.


This is the best comparison I can make, granted, I'm positive the gal in the second video is driving around in Race mode.

No video will really capture how good these cars sound. Videos always fail to capture that really deep grumble and makes all exhausts sound the same imo, you have to hear it in person

Iím in the same boat that Iíd like to hear what I might be getting. That said Iíve removed them on all my previous cars and liked the results so as the soon as the snows off the road Iím getting them removed! In the extremely unlikely event I donít like the sound, Itíd be a simple fix to have them welded back in.

Just realize you could fail your emission testing, depending on which state you live in.

Not perfectly, of course, as input and output of the audio makes a big difference, but the videos I posted are VERY accurate from my personal experience having done the mod in the last 2 weeks.

the second video with the camo wrap. Sounded great but was that dp as well as no secondaries?

If it is, it sounds identical to my car with nothing done to it but secondary cat delete. That said, most of the videos of DP only cars I've seen, sound more metallic and allow more of the turbo spool sound through, but I'm not an expert.

Regardless, I can guarantee, based on my experience, that there is 0 drone from this mod, and it just increases the volume to a better level, and lowers the note an octave.


If you hate it, you can always have to re-weld the cats back.

For those that have had the delete done, was it simply a case of cutting the cats out insitu or was it necessary for the exhaust to be removed? Iíve just got back from my local Ďcustomí exhaust shop and theyíre saying the down pipes have to come off to do this?

What I thought should be a fairly simple job is now being quoted as a days work...

AMG 17GT 04-02-2019 12:32 PM

Cut out. Find another shop.

They probably don't realize there are 2 sets of cats, and are quoting you for the removal of the primary cats, which are part of the DPs, which I advise against. If they drop the panel in the rear, they will have access to the secondary cats (AKA resonators).

go to JPG exhaust in Oakville. He has done the deletes for a bunch of my friends benz's. I don't think he ever paid more than $150

Panel in the rear? Am I mistaking the primaries for secondaries? From what I saw, the cats I saw were on the end of the downpipes (didnít look up towards the turbos). Should I be looking closer to the rear axle?

Huh! Weíre generally charged that for entering the shop here! If only it wasnít for the 3500 kms... :shakehead

You're right, I may have been thinking about the underside backwards. Now I'm going to have to lift the car to double check. Either way, as far as the shop is concerned, it should be a simple cut and weld.

How many cats are on the stock downpipes? 4?

I see some aftermarket downpipes with what looks like 2 cats and others that have none.

AMG 17GT 04-03-2019 07:47 AM

Yes as in picture above 4. A lot of DP’s have 200 cell cats attached.

emericr 04-03-2019 11:11 AM

Cheapest mod on the car. Exactly what you want, no negatives. Should cost you $200 or so and fully reversible.

let me know if you get it done and we can meet up so I can hear your car!

Iím debating it as well and the place I called here in Oakville was very reasonably priced but they also told me that odds are I wouldnít even be able to notice any difference at all!

Not sure what to make of it considering so many here have suggested it makes a considerable difference in sound?
