What I'm wanting to no will it be ok to reduce again to the standard system size near the back box area? Or will it be to restrictive and best to stay 2.5 all way back?
3 inch down pipe is abit extreme I bet the elbow off the blower isn't much bigger than 65mm! Don't forget if you drop back to std near the backbox not only will you need a train of reducers it will flow no better than a std system it's only as restrictive as the smallest parts!
