Badger 5 mk2 80mm TIP is a little more expensive. He does get some really good readings from it though and can add anything upto 20bhp.
SFS 3" TIP are a little cheaper and a lot of the guys here with LCR's have bought them. AmD Essex have just done a group buy on them for a bargain price but it's recently finished.
Preference really mate. If your flush with cash go for the B5 - if you can't justify the difference, go with SFS. I know SFS are only making a couple a day and there is a bit of a backlog but I can imagine Awesone have the B5 ones on the shelf ready to go.
