The premium  high-quality  T-304 Austenitic stainless steel system is easy to bolt on  is a direct replacement for the much heavier (by some 20lbs.!) stock system. A 3\" diameter front pipe is mounted just after the catalytic converter leading to a Y-pipe  which splits into two 2-1\/2\" pipes exiting on each side of the rear. The muffler and tip assemblies use a 10\"x 5\" diameter round muffler on each side of the vehicle  with polished T-304 stainless steel rectangular  rolled edge  angle cut tailpipe tip at each split rear exit. Tests have shown an exciting 41% increase in flow for dramatic improvement in power or fuel economy. That now famous  aggressive Borla(r) growl and sexy look proclaim this block may be small  but it means all business we guarantee it for a Million-Miles! With race-bred technology that has been transferred from the many successful Borla(r) race programs  it was no accident that this Borla(r) system has won several major Corvette exhaust shootouts. Included in this great and storied past are such famous efforts as the C5-R Race Team that has dominated LeMans along with the Bondurant Corvette program at the Bob Bondurant School of High Performance Driving. Only what you would expect from Borla(r)  the most winning exhaust in racing.\u003c\/p\u003e","brand":"Borla","offers":[{"title":"Default Title","offer_id":49285442404656,"sku":"140082","price":1199.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0417\/5508\/2918\/files\/140082.jpg?v=1777325510","url":"https:\/\/trucksrus.shop\/products\/borla-140082","provider":"Trucks R Us","version":"1.0","type":"link"}
