Modifing gte exhaust

[RICKY132]

Curently im running on my gte an ashley back box with the big middle silincer removed.I have bought a 1300 sr 4 branch and mid pipe,which when fitted will do away with the other smaller mid box in my gte as the sr didnt have a mid box on the mid pipe.
Will this system provide me with enough back pressure or does the gte need to run with more than one box 4 back pressure.

Cheers Ricky

the ammount of boxes u have wont make any difference to pressure. the bore of the tube will tho. it must be well loud with an ashley back box an no other boxes as they are renound for being loud anyway.
