Ok since there is no diffinitive answer on which exhaust makes the most hp or tq, or little paperwork to prove it, i would greatly appreciateany and all information on which exhaust is the litest. I thinking borla because it only has one small can.... I tried doin a search but after a couple of hour reading, im just going to use the forum and ask hopefullly you other members could help me out--- ohh yea, this request is minus the tittanium exhausts because thats just too much money for me to spend. Any help would be appreciated, im trying to buy parts for my car and get them out on before it gets sent to italy

They will all weight about the same. Do a search... there is a listing of JDM exhausts in here.

Actually, this last weekend IGOZMZM, Doccable and I all weighed the stock exhaust and the Borla. The stock exhaust weighed 38 Lbs, and the Borla weighed 33 Lbs. FYI.
