Resonated Test Pipe Options
 

Wondering what the best resonated test pipes to go with my ark grip exhaust would be that is relatively cheap. Coming from FI RHFC so would like to keep as similar as possible sound.

I was looking into circuit werks with anti reversion or ISR resonated test pipes.

Fast Intentions make resonated test pipes. You can't get any closer than that.

I've had the Circuit Werks Anti-version model for a long time before switching to ART pipes. The circuit werks definitely helps in removing or keeping the rasp down. I had it with my Top Speed exhaust and also Motordyne exhaust on my G37. I sold it to a guy who has it with muffler deletes and the video he sent me, I didn't hear any rasp.

I also had it for about a year and the welds all still looked good when I removed it. The flex area were fine also.

The one concern I had with these were the flex points, but if yours looked good then perhaps they are strong enough. Do you happen to have a sound clip of these test pipes with the motordyne?

I did a recording but its on my GoPro. I'll have to find some time to pull it and upload it.

This video is the Circuit Werks with Topspeed exhaust on my g37.

It’s your Z the best test pipes I used were the AAM 2.5” resonated test pipes.
