How are you guys liking the Mil.Spec 100-cell? How about the available 200-cell units? My OEM main is holding me back quite a bit, but I do not want to make the car any louder if I can avoid it. I passed state emissions flawlessly this month, so that is not a problem. TIA!
//edit// Ideally, I would like to free up some flow without compromising my car's ability to pass the sniffer. The two or three hundred cell looks more appealing, but I particularly like the fact that Mil.Spec's product has metal innards and is made in the U.S.A. I would probably add a shell/shield on one for visual purposes though.

Listen,
I have a 11 GSR with: Ets intake, upper and lower ic pipes, Cobb down pipe, Cobb high flow cat, stock exhaust, Cobb ap & Ivey tune on top of that and the car is stupid fast. I know I'm listing more then your asking, but just so you know for the future.
Reason I don't have cat back exhaust is cause I can't stand it being loud I'm 38 and drive it to work everyday and of course my wife can't stand the car as is forget about having it louder lol.
And ? Hopefully next spring I will like to get a second tune saved on the AP to be used with race fuel only and no cat and no exhaust, open pipe with a custom straight pipe. So when ever I go to the track I just switch to race gas, switch tune and the most pain in the *** part to swap exhaust out, but then the car will be even stupid faster. I don't mind going thru the trouble of swapping out the exhaust for track days cause my friend owns a shop and it's not like I go to the track every week, more like 3 times a year if so. Good luck

[QUOTE=S2K2EVO;9903974] so you were planning to remove the Hi-flow cat as well when taking it in? Don't think the dealer will honor a warranty if you replaced the Cat, so why not get the Ap much less of a headach to reset
