What's the lead time on a set of FI RHFC's?

I think mine took 8 weeks. That was five years ago.

Thanks all. 8 weeks is long time, but I'm sure it's worth it. Rochester, have you had any issues with them?

funny enough when I installed the exhaust my cousin installed the mid-pipes wrong, n was having a real issue getting the flanges to line up, realized what was going on n swap the mid-pipes n it lined up perfectly but the height of the tips were still sitting low so I just added the spacers.

Can anyone help, I purchase the ark n love but 1 day my n the misses went to a look out on the palisades n when we got back to the car I had my wife do a quick pull for me so I can finally hear the exhaust from outside n I F-ing love it. I notice what seems like a slight ring when she gets on the gas, I took a video n you can hear it but I cant upload the video. Can anyone help me upload this so maybe someone could tell me how to get rid of the ring, you cant hear it in the car but once I heard it I wanted to correct it. Thanks in advance.

Hey guys need some advice, I have an ark grip on my sedan n I can hear a slight ring (if you wanna call it that) when I get on it hard but only from outside. I had my wife do a quick pull for me n that's when I heard it. I'm going to upload the link, you can hear it but its clearer with headphones so if you guy can tell me what ya think could be causing the slight ring that would be great. Thanks in advance.

Nice. And I saw your thread about the support bracket - good little write up. May have to see if my exhaust shop can do something similar.

@Redgoyabean That sounds like rasp to me. Do you have aftermarket cats?

Redgoyabean

No only mods are ark n takeda cai system that's it, during install I used the gaskets provided but reused the original cat gasket could that be the reason. I've seen some ppl used some type of paste between the cats n x pipe, I really hate to have rasp.

I don't think it's real common to see an Ark exhaust rasp, especially without cats. I'd start small and make sure everything is lined and tightened up, then maybe get some better cat gaskets if that doesn't fix the problem.

On another note, are the FI RHFC's much quieter than the Berk HFC's?

Put on the Z1 non-res test pipes on my sedan (will probably do a review) which also has the topspeed Y-back exhaust that had its resonators cut off, the sound and overall loudness was great and exactly what I wanted. Except for one thing, there was a window of HARSH rasp from 2500-2800. Not just normal rasp, it literally sounded like a 4 cylinder with a cutoff muffler worse than even any videos I've seen but everything after that range was perfect and felt great. As such I went ahead and slapped vibrant resonators back onto the exhaust and now its basically dead quiet, all that loudness gained and nice pops are virtually gone . So I guess its back to the drawing board for getting this car loud once more.
And for those wondering, even with resonators cutoff the drone was definitely manageable with the Z1 test pipes even at highway speed I wouldn't say its anything that would give you a headache or bother you if you had music on.

My buddy at AAM always swore against non-res test pipes on Z/G cars.
