Has anybody done a muffler delete with their AA equal length mid-pipe?

I have stock downpipes, non res equal length mid-pipe and stock muffler. It's honestly not loud enough for me and I don't really want to do catless downpipes so the only other option I really see available is doing a muffler delete.

Probably would sound like a raspy version of this:

There are plenty of loud mufflers out there. I just put a Meisterschaft muffler on my car and it's like three times louder than the stock muffler.

GT OEC in stainless. It's the one with the muffler in the middle, rather than an x-pipe, and OE valve control.

Not yet. Here is a video of the same setup on another car:

I started with the non-res pipes on it, and could not hear the fking radio, so I put the resonated pipes on it. Sounds great but definitely loud inside the car for my old ass.

Sheeeeeeeeeit

The last group of buyers waited something like four months. Sounds like their supply/production delays have improved dramatically.

@ Justin - I just tried to contact you via PM but the settings will not allow it to go through. I am interested in (1) of your products & would like to purchase it as soon as. What is the best way to connect?

Yeah I love that sound it makes with non res EL lol

[Slo_F80_Mike]

So I have been running the non res version for a while on stock dp and muffler and now I have been wanting to get catless dp. However, I think the resonated setup with catless dp still doesn't sound that good. Any custom ideas to make it sound better with catless dp, or just keep stock dp?

[mapster37]

im currently running stock dp, EL resonated with stock muffler. shortly will be installing resonated dp's. ill let u know how i like it...

I have a non-res AA mid pipe on order, but I'm very torn on whether or not to switch my order to a resonated. My CS is completely stock now, and I just want to refine the sound a bit without being obnoxious, loud, ricey, flat brimmed hat YOLO car... is that what I'm going to get w/ a non-res?

Stock cats + Nonres is a raw, racy sound. A tasteful touch of BMW S engine rasp, but not too much IMO. Sounds very similar to various 1M exhaust setups. Resonated will lower the perceived volume a tad and takes the edge off, absolutely 0 rasp. Both sound great.

The real trouble occurs when you run catless + non resonated. But with stock DPs it sounds nothing like that.

My new setup with Inked Custom resonated EL midpipe

[Soul Coughing]

6+ Month daily driven Update:

I've had the AA EL midpipe - non resonated - on my car now for 6+ months and wanted to give everyone an update.

Positives:

-The Sound past 4.5k rpm is just awesome. Sometimes I'll just rev out the gears without going WOT so that I can hear the I-6 wail! It sounds so nice and makes the car sound so much better than stock! I also have a valve controller, and run the exhaust open sometimes, and as long as the exhaust has warmed up (3-5 minutes of driving), there is no resonance or rasp all the way from 2k to redline.

Negatives:

-Cold start rasp - It doesn't seem to happen every time, but when I cold start the car, I will get some really horrible resonance/rattle/rasp after the engine roar has settled down and the car is in cold start mode (around 1.5k rpms). It sounds like a civic and can be really embarrassing as I can't lower the rpms to make it go away. If I open the valves, it's even louder and worse. I also can't have the valves open when the car is cold (first 3-5 minutes) and EGT temps are below 550-600 degrees or i'll get low rpm resonance that starts from 2k-3k - especially if I'm giving it more than 50% throttle. I've checked the mid pipe and its not actually hitting anything; I think it's just a resonance coming through. I've thought about getting the resonated pipes, but then I'd miss the wail at redline!

Still an awesome piece and something I will not be getting rid of anytime soon!

Thank you for this update.. i have an 18 ZCP thats stock.. and my big question is resonated or non....

Sounds like the non is a tad more aggressive..

Aside from the sounds, is there any other difference between the two? No SMOG issues?
