Is this rasp?

user123

Hello,

I have a 2019 370z Sport MT with Invidia test pipes and invidia full exhaust.

I'm trying to determine if what I'm hearing is rasp. If I'm standing still in N and rev the car all I hear is the hiss when the rpms drop which doesn't bother me.

What bothers me is this horrible metallic sound coming out the exhaust under load. Slight throttle and there's nothing but pure exhaust noise which is incredible but half throttle to full throttle is this annoying metallic sound. It almost sounds like a rattle/tin can sound being forced out the exhaust. It sounds like if you have the car in a high gear going slow and you floor it. Is this rasp due to the test pipes?

I've checked under the car and there's no leaks. I can see why people put the stock cats back on. I just want to make sure this is actually what rasp sounds like. I'm going to sound deaden the trunk so I can't hear it anymore.

I'm also going to upload a video.
