CLS400 Exhaust Pop/Crackle Tune
Are there any reputable providers like Eurocharged/Renntech that offer just a standalone pop/crackle tune? Assuming it would be noticeably less expensive than a tune that would include performance enhancements.

Not sure if they only provide that tune by itself...but I'd suggest not to get the burble tune with the stock cats on. The extra unburnt fuel can possibly damage the cat cells. I have EC Stage 1 tune + burbles...I believe the burble tune burnt my O2 sensor already. I talked to a few people, one of them a genuine Benz/Porche mechanic, also said that the burble tune is more likely to damage your O2 sensor and the cats.
I'm planning to go cat-less downpipes and Stage 2 tune pretty soon..hopefully this summer.
That's just my experience and what I kind of learned...but not everybody gets the same issues. And you do what you love
And Renntech is just too pricey lol EC, Weistec, OE tuning are all good. I've heard just one or two people running AMR tune.

Your welcome.
I mean I know another person running burble tune with stock cats and his ride is running completely fine. So not everyone will run through this issue. But somehow I had to deal with it. It gave me such a headache bc I couldn't locate the problem, until I finally got the CEL and replaced the O2 sensor. There was a lot of misfire happening.
Don't want to scare you guys off, by all means go for it. But if something happens or misfire with burble tune + stock cats...check the O2 sensor first before spending on other parts.
This was just my experience
you might not get into this issue at all, who knows

I have my car tuned stage 1 w/pops with OETuning, and have the secondary cats & resonators removed. The primary cats are still in place and I haven't had any issue thus far, and it's been about a year. They have been great so far in terms of support and providing guidance and information when needed.

I know 2 other ppl running the burble tune with stock cats and is running fine. So not all apples are bad.
Have fun
