i'm currently can-less and it'll be a couple weeks before i get my stainless-gp canister.  i'm running 2-1 collectors and was wondering if it's a bad idea on my '05 S4R.  i still have the stock mids with the udder. 

You should be fine.


The neighbors may not like you.

i don't think they'll be happy afterwards either.  the gp cans are supposed to be stupid loud, albeit a better sounding, deeper loud.

at least you wont have to worry about floating a valve.. thank you desmo!
