my mods are in sig.
1) should i switch my ultra-flo's for flowmasters (to possibly add backpressure) since ultra flo's are straight thru?
2) should i change my tailpipes to 2.5 instead of leaving it factory 2.25 from mufflers out?
3) 4.10's or 4.30's?
4) any other N/A mods i can add besides headers (cost)?

i have not been to track yet........but did win races against 3 lightly modded 99+ GT's, modded 5.0 & an 02 lightning with a K&N filtercharger this last weekend. all agreed that i am 13.4-13.60 & i dont have nitto's on yet.

5) with gears, nitto's & SCT dyno tune by jerry & chris how many tenths should i drop?
6) should i have SCT flash or chip?

thanks for help
