Oh yes, its the stock OEM exhaust pipe, just got an exhaust shop to cut out the 2nd cats and welded a stainless steel pipe.

Awesome, thank you for clarifying! So that should be basically the exact same thing as the Supersprint front-pipes. Cool.

I get the thread's purpose, but c'mon.. this is an internet forum - you can't expect there to be no discussion at the same time. I'd say the best we can hope for is to at least stay semi-on-topic, which I believe we are doing quiet well at here!

I promise I'll post up a sound clip eventually!

There are literally multiple threads on this discussion you've already had, right on the first page. Some of us actually come here for useful information and discussion, not regurgitating the same thing in multiple threads in the same place. Your "venting" thread is a prime example of this redundancy.

What the fuck ever. There are at least 20 working YouTube clips in that thread. I know, I've watched them. Of the active members here, I must have done one of the most recent exhaust installs. I've been all over this topic in what might when be considered an unhealthy amount. Nothing in this thread is more than a single phrase Google search away. If you want to bitch about redundancy, be logically consistent with it. Otherwise just STFU. You're one of the more knowledge people here. There's no reason to behave like a dickhead.

Currently running muffler delete and secondary cat delete.

This is a comparison vid to see if secondary cats made a difference so you can listen to both setups.

OH and btw im Looking for cheap ebay headers if anyone knows some for sale

For those of you who have axle back "exhausts" (basically mufflers) such as the AA Signature Gen 2, Rogue Ikon, BMW PE, etc. Does removing the resonator create droning?

I currently have the Rogue Ikon exhaust, it sounds great, no droning, but I'm looking for something a little more raspy or louder. I'm just concerned that by removing the resonator it will drone?

I know the BMW PE does not have resonators and it doesn't drone so...shouldn't this set up also not drone?

You can't assume all mufflers are created equal and this will behave the same with the rest of the exhaust system. The only way to find out is to do it and see how it goes, it's not that expensive to cut out the resonator and replace it with straight metal tubing. Or hope that someone else here has this exact setup and chimes in.

I am currently running the AA gen 2 axel back with a smaller resonator and secondary cat delete. Sound is great with very very little drone, with a bit of rasp.

This will soon change as I have AA catless ceramic coated headers to install. Should make a big difference in sound and a bit more power.

For those exhaust experts out there, should I reinstall the secondaries to off set the primary cats being gone??? I figured it may help with smell and keeping the sound from getting to loud. Thoughts????

What do you mean a "smaller" resonator? Your shop made a custom resonator for you?

What's inside a resonator anyway?

Well, he showed me a bunch of other resonators that were a lot smaller with less insulation and packing inside. He suggested I keep some kind of resonator so the drone would not get out of control. Not sure the brand but I could find out. It was a lot smaller then th OEM resonator. Im very happy with how it sounds, it actually got better over time.

6ixSpd · 04-04-2018, 04:22 PM

I would definitely re-install the secondaries. The smell would be pretty bad for a daily driven car, and downright unhealthy to be breathing those noxious fumes in all the time.

Ok thanks. I might just do a resonator delete and replace them with a Y pipe. I feel like your AA exhaust is louder than my RE Ikon and if yours doesn't drone then mine should definitely be ok. Also not to mention you also have a secondary cat delete.

I’m kind of leaning that way, that’s why I saved them. I knew I would eventually get the headers just not this soon.

My car isn’t a daily driver tho....so maybe no cats???? Hmmmmm

6ixSpd · 04-04-2018, 05:12 PM

I had a catless setup on a car in the past, never again. The fumes are absolutely not worth it when you can toss in a set of high flow cats (ie. your secondaries) and filter out the vast majority of it with no appreciable loss in power. In fact, several friends of mine ran catless exhausts on their cars for a while only to put high flow cats in afterwards. The trade off isn't worth it all.

Thank you for the input. I most likely will reinstall the secondaries. My exhaust shop said it’s no big deal to put them back in. He actually recommended it also if I did catless headers. I will post an update after the new set up is done.

atmosphericM · 04-05-2018, 10:18 AM

I've had a few cars with no cats at all and the smell has never bothered me. I never even notice it. That said, I'd probably run secondaries if no primaries to reduce the sound levels depending on your setup.

BimmerNugget, my suggestion to you is delete the secondary cats. This should give you more sound, more rasp, and more power.
