ATM im just running a K&N panel filter and a 5zigen muffler. My muffler however since the drags is now blowing black fluffy stuff, kind of like insulation, out the tip

guess its wore it out. dont know if the octane boost had anything to do with it??
I think a 1.7sec to 1.8sec 60ft time is possible. If i get that i should be running pretty close to 14 flats
