NHP Catless Race Headers sound
I couldn't find any info on these products when I was choosing exhausts, so I decided to make a couple of short clips of my 2.9L Boxster with the NHP Race Headers, Baffle delete, NHP Y-tube, Schnell Power Flow Air Inhaler and Softronics ECU Flash. I also have a custom 8" extended single straight tip. They each contribute in some way to the sound. It's kind of metallic, mechanical sounding at idle. And at redline it's kinda like a swarm of bees busy. From 3500-6500 though it's raspy, angry, good mechanical, kinda vintage sounding. And it's pretty loud! And yet there's no drone and at sub-3500 rpm it's quiet and unnoticeable (maybe slightly more bass).
