Yeah, those SLP's are pricey but you get what you pay for. I was looking into the Pacesetters, they have good ratings but have some issues with leaks unless a guy gets ZZP's additional package. I'll have to think about it. I've got a K&N 57 series cold air intake if that's what you mean. So that's off the list. From what the two sites I've been going back and forth from say that I can drop down to a 3.6" pulley once I've got the headers/downpipe, intake, then after the smaller pulley is installed, the shorter SC belt. Then that brings me right back to tuning the car, lol. Thanks! It's pretty cool being a dad, tiring as hell though haha!
