Zaust ! New Garage Whifbitz 3.5″ system

Garage Whifbitz have just received the new batch of their own exhausts, so I thought I’d  kindly try one out for them!

These are now 3.5″ twin box so quieter than the old single box version. They measured the noise on my car and it was 105db at 5000rpm, thats with 3″ downpipe/midpipe. Should just about be quiet enough for most circuits, currently looking at making the system even quieter. Certainly worked ok at the last round of Time Attack giving me the  2nd win of the season 🙂
