Thanks. I'll keep checking ebay etc. Looking at a Piper full exhaust system and whether to go for a 2 or 2.5", silenced or not. Good shout mate.There are other inlet manifolds about which are a copy of the DBilas one but finding them is hard. Keep searching on the various selling pages Ebay etc.
There is also the exhaust side to look at, Piper do the full kit which is of top quality and gives good gains.
Then also look at getting the head flowed and bigger cams fitted if you have not done so already?
