I went for the tri-y pacemakers as you need a bit of low-down power with an auto. Pacemaker recommend the 4into1's for blown or stroked motors which you're not gonna do.
Rest of my system is twin 2.5" cats and then on into a single 3", but a single 2.5" would do unless u want to take the motor further.
Factory setting for the timing is 30degree BTDC +/- 2degrees. Mine was running hardly any timing when i got it so make sure u get it checked!
