I would concur with everything you've said.

This is a good point that nobody really mentioned before in this particular thread... it definitely is much louder outside of the car. When I rev mine with the door open in the garage it hurts my ears, but on the inside it's very tolerable.

But everyday I am reminded by pedestrians that the car is quite loud. My wife thinks Im speeding down our street everyday, yet I never break 20 mph. If you want the full effect, just put down the back seat. That always reminds me how loud the system is.

Also, no drone whatsoever, and the sound is very very deep and aggressive. I too have wondered if the ATAK would have been the better choice, but honestly I didnt want to flirt with any kind of high pitch or hollow sound. When I purchased the S-Type I was willing to sacrifice 4-5 dB for a deeper and more refined sound. My coworker with a 2016 Mustang 5.0 with Roush axle back even admired the Borla system and claimed it sounded very deep compared to NPP, and he quoted "thats the perfect sound, just the right amount of volume and tone".

Its a "grown-ups" system guys, but it def matches our Gen6 Camaro's new street swag of being a more refined sports car. The quality is second to none and everyone knows of Borla's reputation.

Hope this helps all in question on what system to get!

when i bought my Borla System I was worried I spent too much money. After 2000 miles on the system myself I know that I made the right purchase. The sound is perfect. 11924 + 60609 here.

So there aren't any O2 sensors or anything in the secondary cats? Just pull them, replace with cat delete option plus cat back S Type and your good to go?

This is what I want to do very, very soon.

I'm just trying to research everything thoroughly so I don't run into any CEL problems.

there have been CEL problems with secondary cat deletes from improper welding, so as long as it is thoroughly welded, you should be ok.

Ok, so is there welding involved with the borla system w/cat delete? I thought one side was a slip joint/clamp and the passenger side was studded?

Just trying to learn.

idk about the borla one actually, the CELs that I've seen were from people doing custom secondary cat deletes at their local muffler shops, haven't read of any issues with the clamp-on name brand stuff. but as long as the delete pipe is properly fit and sealed, I think you should be ok with no CEL.
I still have my secondary cats on.

Thanks for the info.

The Borla systems secondary cat delete is easy. One side is a slip fit and one side is a bolt up flange just like the stock system. All you have to do is grind off the stock clamp on the drivers side (super easy) for the slip fit. PAssenger side bolts right up. You need to move the O2 sensor to the new pipe on the passenger side. The driver side is on the stock manifold after the primary CAT so you don't have to move it. No leaks, great fit, no CEL's.

I love my Borla 60609 and 11942 setup. Amazing sound.

That's exactly what I needed to know. Thank you. So that is the part numbers for the 2 systems that I need to order to keep my npp and have the secondary cats deleted?

I need the 60606, since mine is an M6.

There's no welding involved in any of the Borla midpipe or axleback systems. And yes 60606 is the correct mid pipes for the secondary cat delete with no AFM, here's the install instructions and diagrams for all of the mid pipe options:

Thanks, I had looked at that pdf 3 or 4 times and neglected to see that install. It says the 60606 slips on the cut ends and it shows the 60609 slips on the factory end and flang. I was under the impression that the only difference between 60606 and 60609 was the AFM module?

[gdgraph]

You may be mixing up the numbers.

60606 mid-pipes & secondary cat-delete / no AFM
60607 mid-pipes no cat-delete / no AFM
60609 mid-pipes & secondary cat-delete / with AFM
60610 mid-pipes & secondary cat-delete / with AFM

The ones with the secondary cat deletes (60606 & 60609) the left side slides over (lap joint) and the right side flanges up to the primary cat.

The ones with no secondary cat delete slides over on both sides with lap joints and then you throw a clamp over them.

Check out Page 2 & 3 for the diagrams, it'll make more sense. Page 2 are the two non-AFM mid-pipes, Page 3 are the two with AFM mid-pipes.

No problem, which axle back are you going to pair with your mid pipes? Going S-type or Atak?
