Secondary cat delete with oem exhaust mod?

[MTrezzz]

Anybody have a Video of ACM mod with Secondary Cat Delete??? I would love to hear this.
Or ACM mod with a Resonator delete and keep the cats?

Not looking to be to loud, something in-between PRI CAT Delete with ACM MOD.

I don't think the secondary cat delete would make it much louder since it is essentially a high flow cat already. My guess is that it would get more raspy. Hopefully a video you asked for confrim my guesses.

If you have the perforated OEM mod, dont touch the cats unless you want major rasp.

Did you try this Gator or hear it in person?

Hi had the OEM exhaust and then put test pipes, but it was too loud for my taste. I went back and perforated the two pipes and now the sound is awesome. As everyone else mentioned, the secondary cats are already high flow, so no point in touching them.

So basically OEM mod with test pipes = just right sound.

Curiosity got the best of me so I tried it, just never came back to update this thread. It was a noticeable increase in volume which I was happy with. However, it was very raspy. I kept it that way for a few months before I got tired of it and had resonators welded in where the secondary cats initially were. Moral of the story is that the oem mod sounds great on its own and needs to be left that way.

Haha, nice! I love the OEM mod but I'm looking for a new rear section because I would like a little more volume and would love to try a custom primary HFC setup. I know everyone will be like "just get TP's", but that's not the whole story. Getting off topic a bit, I think you can legitimately place two 200cpi cats in place of the stock ones and make some HP, improve sound and avoid the CEL and smell issues.

Side note ...want your rear section back?

secondary cat & resonator delete is a huuuge sound gain.
No CEL as well.
I'm using Kreissieg F1 without secondary cats & resonators

Ha if you were still local I'd consider taking it back!

Which rear section are you considering?

So is oem MOD and secondary delete too much or perfect

It's way too raspy, leave the secondary cats on.

It is the best sounding ive ever heard... Goodluck on the future decision !

I would have to agree. That sounds ridiculous. Been toying with exactly this idea.

I have oem exhaust mod, test pipes and secondary cat delete (oem resonators) and it's a lot louder than test pipes with oem exhaust mod. Perfect setup in my opinion is oem exhaust mod and test pipes. Zero drone and sounds great on WOT
