pro circuits are a low/mid pipe. i guess youll be going to a different pipe with the dune port? if so, bigger carbs will give more top end.
i also think that 28's would be ideal for your current setup.
bhq has the best builders in the biz as site sponsors. i personally would recommend wildcard racing but i have dealt with FAST and have talked to kevin at hjr before and they are awesome builders and very helpful also. call em all up and talk to them and take your pick!!
agreed with everyone else. dont pay that much for that thing! 2700 alone is waaaaay too much not mentioning the shipping costs. search craigslist for something closer and cheaper.
