alright. i have a 2002 tomos lx. upgraded 67cc airsal kit. i am 15 years old and weigh 190 and only getting heavier. my biturbo just isnt cutting it for me i need some more torque but also dont want to sacrifice all my top end. which pipe from this list would be the best for my situation? the estoril seems to be accepted as the best but i would be grateful for some opinions http://www.stevesmoped.com/component/option,com_virtuemart/page,shop.browse/category_id,3/Itemid,244/vmcchk,1/
