so 2nd cat delete? stock resonator delete?
i'm sure i don't want to touch the DP at the moment.....
like above statement, if 2nd delete will affect any emission issue?

which one gives me less drone while cruising but better sound than stock?

I will see if I can get some highway sound clips either today or tomorrow of my resonator delete (interior)... I will say that I like the sound I have when driving around the city, but I haven't driven on the highway since i did the delete, but to each their own...

thanks.... is that much louder than stock or just slightly noticeable? currently i have stock with golf tee only.. it does sound good, but i want it to be a little deeper and a little meaner... that's all i want...

Delete the resonator. E92's come stock without a resonator, so if you want to know how your car will sound without one, go listen to a coupe.

i'm running stock midpipes and mufflers with AR catless downpipes and i think it sounds great. i love hearing the turbos spool up faster plus the added hp is a big plus.

It's def louder than stock, louder than the gold tee mod... I'm tempted to do the GT mod to see if it has any additional change on the sound with my current res delete. To me it sounds meaner, more like a car with turbos should sound. I will try to get some sound clips... Im wondering when I put my **** back in if the exhaust sound will be more pronounced or not... but have to wait till after dealing with the stealership for my free maint...

He wants a deeper tone, and getting rid of the secondary cats will achieve that, plus he will still pass emmision testing because he has the primary still in place....There will be no smell either.

thanks for all suggestion guys....
ended up i went with an x-pipe.......... and i undo my "golf tee" so normal cruising it sounds so quiet which i like.... and when i get on the gas, it definitely louder than having golf tee....
that is a good setup since when wife is in the car, she doesn't want to be annoyed by the noise when cruising on freeway especially long trip, and when i'm driving by myself, i can relax and listen to the music when cruising, and get on the gas, it gives a beefier tone than stock system with "golf tee" only....
x-pipe with golf tee is just a bit too annoying while traveling ~70mph on freeway even with very light throttle....
so i undo the golf tee, tested it out, that works perfect to me
