I used to have the Perrin/unresonated and thought it sounded pretty good with stock manifold but as soon as I went uel that all went out the window

beautifully made too.
As for STI - it's early days but it's more than I was expecting, superbly made, beautiful looking exhaust with gorgeous large angled tips

bigger is better

they look so much better in person & then you start the car and suddenly realise it's louder than I was anticipating @ low revs & tappers off to a light growl after 3Krpm & beyond unlike the Perrin which actually got louder & raspier. I was hoping for a more subtle note @ lower revs but it does sound deep & ballsy just like a Rex - BR86 now sounds as good as it looks.
I'm thinking of making a slight mod to the midpipe only, looking to make a new one & see what that sounds like otherwise I may just leave it. My neighbor reckons it's too quiet

then again he got a really loud Skyline.
Stay tuned
