I'm with you 100% on the BOV. I liked the sound of my GFB 50/50 - but the car would run funny. I LOVED the sound of your SSQV - but if it made the car less fun to drive - to heck with it.
I like the way your Greddy sounts. PRETTY darned quiet, maybe a bit louder than my Prodrive - but looks more "import racer-ish" which is the in thing now.
My VF30 made my exhaust WAY louder too. Weird, huh?
