Is that last picture, is that where the end of the ARH setup meets the stock exhaust? Right at the resonator there? That area is all straight pipe for me now, so I'm trying to judge how the exhaust shop is going to fab something up to work there.

Well, got them all installed and although it sounds really good, it's REALLY loud, like racecar loud - and this is coming from having no resonators, second cat delete with an h pipe before (not even close to as loud). My car is catless and no resonators, so just the factory mufflers. I wanted a loud car but it's a bit much and it also crackles and pops excessively anytime I let off the throttle, even to coast. I'm waiting to hear back from EC to see if I got a burble tune by accident but I'm also thinking about trying to order the elbow pieces with the 200 cell cats from ARH in the meantime. I just don't know what to expect from them. I really only want a slight bit of the rasp/loudness taken away and a lot of that snap and crackle when I let off the throttle (if it's not tune related). I read a few posts on here saying that the setup is still rather loud with the cats so I'm thinking those catted elbow pieces might be a good purchase for me?

Those crackles are not because of burble tune, it happens because you have no stock resonator to cancel out exhaust frequency downstream. I have tried all combinations. PM me your number if you want to hear how each setup sounds. Only cheap and easy way to completely get rid of crackles and raspy sound is install the stock resonator back period.
Are you not the same guy that asked why I'd want to put in a resonator just 10 posts previous to this one? \/
Why do you want to put a resonator. Crossing exhaust stream twice that’s too in a short length difference can cause turbulence in the flow which would develop eddy’s. Such eddy’s can not only affect your scavanging action but would also increase unnecessary back pressure. Further more it can affect the exhaust tuning wave timing.
I hope it helps.
I had a full IPE system that didn't crackle and pop like this. I mean, I love when I get a few as I'm slowing down or coming to a stop but if I'm not pressing the gas it's sounding like a drive by. I don't have the stock resonator and with how that area is all custom now, putting it back in isn't really an option anyways. I could try some random companies resonators but i think that would just change the car and make it sound weird. I'm just wondering if getting the AR elbow sections WITH the 200 cell cats would help take just a tad of the rasp/bark off it (not a must) but more importantly get rid of the mexican cartel gun fire whenever i'm coasting. They'd slip right in place of the catless ones with ease. Seems like the easiest route but I don't know if it'll work? Generally cats seem to get rid of that stuff though.

If you get a few mins you should upload each one to youtube and post them here, curious to see how they each sound and differ.
edit: woke up to a new tune from jerry and ALL of my over run pops, bangs and burbles are gone. I actually don't even have any as I come to a stop like I did when I was stock but at this point I'm probably just getting picky.

So you were accidentally sent a burble tune by mistake & that was the culprit?

I'm starting to wonder if and how it would be possible to data log and send back what I've found and really have the tune dialed in. Living in western Canada our air and fuel is rather different to you guys in the states, if probably benefit from some data logging.
More back on topic, so with the long tubes, catless x and no resonator the car sounds absolutely amazing if you get on it anywhere between half and full throttle but sometimes driving around slow I get a little bit of trumpety/raspyness to it and overall the car is a bit loud, even for me. I'm thinking about ordering the elbow pieces from ARH that have the high flow cats in them, I'm curious how that might change exhaust note?

Okay so I'm pretty sure I'm going to weld back in the stock resonator to my ARH/catless X/no reso setup. I think it'll get rid of a bit of rasp and sound overall pretty good, I'm just worried it'll quiet it down too much at low rpm. Anyone think it'll make MUCH of a difference in the overall loudness?

I'm looking to get rid of that part throttle rasp around 2k rpm, at WOT it sounds perfect now. I don't want to lose TOO much loudness though. A bit is fine.

Did your tune turn off any o2 sensors in the exhaust?
