dont want to sound like a noob, but i just inherited a 120y wagon.. 100% stock 4 speed, and i put a 2 inch exhaust and strait through muffler on it.. now it is really quiet.. im not sure if my expectations are too high (with loudness) when we cut it off under the front seat before we took it to the exhaust shop.. because that was literally deafening .. but i loved it, so id the manifold to restricting for the larger exhaust, should i get extractors.. im not looking at modding the engine at all, besides new leads and plugs, and maybe tune the carbie a little.. should i cut the exhaust before it goes over my diff? or just take the muffler off :P.. just annoying because i actually paid for it to be quieter..
