Its strickly an exhaust video

you are free to make your own videos without our watermarks as many have done before. I do appreciate the consideration though! just make sure you post it as as I love listening to all sound clips as good or bad as they might be haha

Also, on another note:

Khoi, I'm sure it's part of what is considered for the midpipe, but maybe you can make a solution that will work for your test pipe users. As you've heard from my video, it can be pretty damn raspy. I don't mind drone all that much (and because it doesn't affect anyone outside the car) but the rasp at 3000 is a bit much for too long.

I just listened in on your other clips now and it sounds pretty intense off throttle and right in between WOT shifts

I'm actually pushing for AAM to make resonated test pipes at the moment becuase it just doesn't seem you can get rid of the rasp/drone no matter how good of a catback you have

over the weekend I met with a few 370z guys, one who had FI LTH's with an ARK Grip catback. as good as it sounded it still has the off throttle hiss and rasp at a certain RPM range. As you know ARK Grip's are well resonated with decent size resonators, big mufflers at the end, as well as resonator tanks on their mufflers and even with LTH's you still get in the inherent hiss/rasp. I'm starting to believe it's just the nature of of the VQ37HR's

It's funny because I had this same conversation with our engineer and he said he has this same issue with his 335i, where there are certain RPM range with drone/rasp even with his car and that adding these resonator tanks, depending on the location and size only mitigates and changes the range which the rasp kicks in. With these resonators they can only capture a certain frequency (given the RPM) but there's no definite 100% solution, especially when upgrading to a bigger diameter, wanting the extra noise, and completely trying to avoid the rasp/drone. Really is a tough challenge
