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!

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

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

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.

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...

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?

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.

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

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