Its a very well designed exhuast, super light and looks really good on civics. I used to love mine on my old b swapped ej9, But with out the silencer bung in it was ridiculously loud specially with and aftermarket mani and de-cat. Its also highly unlikely it will pass and scrutinisation at track days. the sounds of it with the bung in is beautiful best sounding civic i've heard tbh, however its very restrictive. There was a chap in the us who had his b16 mapped and dyno'd with the bung in and out, the difference was 20bhp which is alot. But if your hard buy it.
