yeah, still running stock system on mine too. do you know if the restiction stops it from reaching factory boost limit. and did you end up getting your tacho to work?.
dont know about quiet though, sure driving normally no one would be the wiser but when i boot the thing theres that much noise from the pressure built up in the exhaust it sounds like a bloody airplane. horrible noise.
where are you thinking about getting exhaust done.
ive been looking at variflow exhaust. theyll custom make everything for me right down to a 3.5inch cat.
i think there was a wire the was either earthing out or not earthing correctly but i don't care it works now and feels great when you drive slow (lol yeah i know but it felt horrible at low speeds)
well i know that i'm going for a 3" (cat ect.)system cause i have the barrel 3" muffler already, and getting the dual dump pipes as well i think should cost me about a grand
once thats in i'll put in the filter and apexi S-AFC...should feel nice and that's where i plan to stop with it...well.....maybe a little more boost
