Its the insert which is much quieter than the stock one. Its more of a wooshing sound. Its barely used. I put it in my car for a few days. Then put it in my friends car for a few days. Neither of us liked it. So yeah. Some of the purple is coming off, evidently its not put on very well. Its not for decoration anyhow.

New they're $20 ish. I'll let this go for $15. That includes shipping & paypal.

i've nvr heard of how the purple insert sounds on the ssqv. got video?

no sorry. Try blowoffvalves.com maybe theres on there.

im pretty sure presure2 was looking for this.
