New Exh for VQ35DETT Nissan March

The dyno session where we hit a new high score of 575Kws at the hubs recently indicated there may be to much back pressure form the twin 2.5" exh systems. So I've finally bitten the bullet and upgraded to twin 3" systems - NOT a small task! In theory there should be gains to be had from this, we will find out when we get her back on the dyno at some stage. Sorry the volume dropped at the end, the mic plug got pulled and the mic on the phone isn't great!
