hey guys due to a windfall i'm giong to get a new exhaust next month (after exams)... i'm pretty much set on a 2inch, and yes i've read all those pros and cons in the forums, and asked an old old mechanic about it... unanimous decision was 2 inch... according to the old boy, no matter vtec or other "jibberish" as he puts it... a 1.6 (i have a ek4 b16a2) should never go past 2 inches unless ur talking FI or hgih high output in excess of 250HP... he went on for ages.... about scavenging, etc etc...

ok so with 2 inch... i'm looking at the mugen twin loop thing design, (probably get replica, i dont print money with my an*s) ... but nwo i have the question... my car ALREADY runs 2 inch piping... is it REALLY worth changing the piping? or can i get a hiflow cat + the muffler with the original piping? i can afford either way, but dont wanna waste dosh unneccessarily

cheers peeps... and btw if u want color coding refer to my other thread, try get u guys a group discount if my family friend is up for it
