whatever you do, dont go to

not because of their product quality (in fact, the quality is pretty awesome)--- they are just REAL expensive. I ended up paying a little over $200 for all of my hoses and clamps (5 hoses, 10 clamps). Some of the reducers and 90 deg bend reducers were as expensive as $60 each.
Uhmm if you want some cheaper ones I know 240sxmotoring.com has some that arent too bad. They're kinda all over the place. If you want a real cheap option try cutting up big radiator hose from napa-- Ive seen it done and with nice clean clamps it doesnt even look that bad.
