Where can I?
 

Evening all just on the lookout for some uprated injectors either 440 or 550 injectors any ideas where I can get them from and which ones are the best to buy?Also is there a difference in performance between a 2.5 and 3.0 inch straight through exhaust or is it just a myth and you get the same performance from both?

Anyone there!

you get injectors from any of the tuners on here or any performance shop. size depends on yr bhp goals, this applys to the size of the exhaust as well
