I need advice...... New power is on the way....ie large cam, LT's with off road mids no cats, 3200 stall and a tune (for now) I should be putting down well over 400rwhp. I already have Magnaflow catback with xpipe and LPE CAI and QTP cutouts. I am sure I will get nittos...... but which ones are going to hook on the street (not a track quenn here) 555's, NT05 or NT01's? GO. this will not see heavy track days but will put it on. Not a DD and will not see over 5k a year.
