If you're gonna run a turbo, one box is fine,

I made a complete system including a straight through back box and it's not significantly louder than standard :D

I'm in the process of having some centre pipes made up to replace my centre box. Atlast i have found a welder who can so I'm in for a new set of ss centre pipes and also some odd bits here and there. Just got to pay for it now :cry:

Lennie, what have you done to your floor pan!! I have to see that fitted :D

Ants exhaust is very :cool: would be ultimate sleeper system apart from the twin 4inch pipes sticking out the back :jester: :jester:

Martins M3 turbo was a single box and that was loud at revs, sweet tho :D

Alex, you aint heard yours at screaming at 7k yet!! (p.s.hurry up and tell us what it does sound like :twisted: )
