Thanks Ry, down in Southampton again now though unfortunately! Thanks bro! The Buddyclub is another level up haha. Should hopefully be going to see Mr Rogers next Sunday Yeah the HKS is a bit too quiet, I was considering it for the angle but have decided against it It's not the MOT I'm worried about but more so track regulations. NA failed it with straight through lol Thanks for all your replies everyone! Think I'll play it safe and fit one small centre box so I can make sure it's quiet enough for track. If I don't think it's loud enough I can always get another straight section fitted Hopefully will have a new system on the week after next
