whats next for my 12 express?
Ok, i have the mod bug bad and im looking for the next thing to do to make it quicker. Last week i installed a k&n cai and 4.10s.. the combo seems to have really helped but i still want more lol.. What should i do next in order to get the 1/8 mile ets down? converter, longtubes and magnaflow, any other ideas?

wow, i just looked up some longtubes..def not gonna drop 1500 bux for headers so i guess thats out of the question.. what other things would be noticable? catch can maybe, clutch fan delete?

~3,000 rpm stall torque converter(circle D, Edge, etc...), magnaflow or other straight through muffler, free flowing y pipe, maybe fastman TB.

A catch can is a good mod but doesn't really do anything for performance.

I wouldn't remove the mechanical clutch fan because with a 2012 you can't get a tuner to adjust the efan settings. A 180 tstat won't do a whole lot on it's own but will only help keep the engine cooler.

Slicks? Shorty headers?

yeah i didnt even think of not being able to change the setting on the fan.. right now im kinda leaning towards a converter, there def isnt any need for slicks yet, this thing will only spin for about two feet out of the hole and i think thats actually helping a little by getting the rpms up.. ill know for sure friday night if the most recent work helped after i go to the track

does anyone have the part numbers for the correct 18in magnaflow (factory duals) and magnaflow y pipe?

snrusnak 05-23-2012 10:28 PM

yeah a small amount of tire spin is good. But once you get a stall you'll likely have issues lol.

buy an R/T converter or a circle-d/edge if you want higher than 2600 stall

GhostR1der 05-24-2012 09:07 PM

I would do 14 magnaflow and y pipe then 2800-3000 stall. It seems the stall is the mod to have for the money.

i got a wild hair today and went to the muffler shop and had true duals with magnaflows installed..left the resonators on the back but it did do away with the y pipe.. can really tell if it helped much or not, its def a little louder still seriously considering a circle d stall for the next step...on their website they only list a 545rfe, is that the same stall that would be used on a 65rfe in a 2012?

CHVYKLR 05-25-2012 01:09 PM

did you have a h-pipe or x-pipe welded in before the mufflers?
got any sound clips?
