4" catback exhaust

ok i tried a search but yielded nothing..

i have access to a good amount of 4 inch tubing(4 inch sch. 5 pipe.) and i looks to be enought to make a full exhaust, but i wonder if a 4 inch is to big???

i would just make it DP back their is no room to do a DP.

i have the V-band flanges and everything to do it also so im really just waiting for some info on a $ inch exhaust. do they make mufflers for it??

thanks guys

there was a thread from buschur where they compared a 3.5 inch exhaust to a 3 inch... if i remember correctly there was a power loss with the larger exhaust. dont have the link, im sure someone will post it...
