i've been building exhaust systems on eb's with 2.5" and its been working great. just finished a long tube header w/ BC exhaust, mine is all 2.5 tru dual w/cross over and 40 flows...dumps over 9". i just bought a nice mandrel bent DIY kit from speedway motors...4 90*,4 U's,4 45*,4 straight 5' sections...all for $139 plus shipping. hard to beat that. i'll be using this to build a BC style on tommys rig and maybe a BC style on mine.
of coarse with that being said...2" mandrel is probably just as good and a lot easier to fit in tight places...makes running tail pipes easier too. if you not using a modified motor...just go 2 and save some money
